  1. Newtons first law is that an object in motion stays in motion and an object in rest stays in rest. Two examples of this could be if you are in a car going 40 mph and the car stops, if you are not wearing a seatbelt then you will go flying out the windshield at 40 mph. Another example is if you have a tablecloth with a plate over it and you pull the tablecloth off the table, the plate will not fall of the table and will instead fall on the table.

  2. Newton's first law is that an unmoving object stays still, it doesn't move. An object that is moving moves in the same direction, but a force can change its motion. One example of Newton's first law is playing a game of catch. Another example would be writing with a pen.

  3. Isaac Newton is saying that an object at rest usually stays at rest and an object in motion stays in motion until acted upon by an unbalanced force. The first example is when you pick up a pencil to write you are changing the position of the pen. You are the unbalanced force acting on it. The final example is when you catch a ball after somebody threw it to you. When you catch the ball you are putting an unbalanced force on it, therefore it stops.

  4. Newton’s law states that anything at rest will remain at rest and something in motion will continue to be in motion unless acted upon by an unbalanced force. Two examples are if a soccer ball is at rest and an unbalanced force such as your foot hits the ball the ball will be in motion. Another example is if you through a stick and the dog stops it by catching it in its mouth.

  5. If an object is in rest, it will stay in rest. If an object is in motion, it will remain in motion, but an unbalanced force can stop its motion. An example is when you are riding a bike and there is a flower pot in the way you are going. You do not see the flower pot and you bump into it.That is an unbalanced force. Another example is when you are in a roller coaster. The roller coaster breaks down while you are going super fast and has a sudden stop. If you have your seat belt on you will stay in the roller coaster, But if you do not have your seat belt on you could flip out of the roller coaster and be injured.

  6. Newton’s first law of motion states that, if there is no outside, or unbalanced, force, objects that are still, or at rest, remain still. Also, an object that is in motion keeps moving. For example, if you pull a tablecloth off of a table very fast, a cup, which was on the tablecloth, stays put. This is because the cup was at rest. It did not want to move. Or, imagine you are parked at a red light. Then the red light turns green and you hit the gas. The car speeds forward and you slam against the back of your seat. This is because you were at rest.

  7. Newtons first law, to me states that anything moving will continue to move, and anything not moving will remain not moving unless an unbalanced force is acted on upon it. An example of this would be hitting a baseball. This would change the direction of the ball. Another example would be picking up a piece of paper. This is because you are putting the piece of paper in motion, by being the outside force.

  8. To me Newtons first law means things that are at rest or are not moving tend to stay like that and things that are in motion or moving tend to stay that way until force is applied to stop it and it will slowly slow down and then stop. An example is when you are about to kick a soccer ball. Your foot is moving and the ball is at rest until you kick it. One other example is when you are about to hit a golf ball. The ball is still while you are swing the club at it. When it is hit it will no long be at rest.

  9. Objects in motion tend to stay in motion and objects in rest tend to stay in rest unless an unbalanced force acts upon it. An example of inertia would be if you were standing on a bus. When the bus suddenly moved, you fell backwards onto the ground. When the bus was at rest, you were too. When the bus was in motion, you also were in motion with it. Another example would be painting. Your hand was at rest along with the paintbrush. As soon as you started painting, both things were in motion.

  10. Newtown's frist law of motion is saying that when a object is at rest it stays at rest or that a unbalence force comes upon it.One example of this is when a bicycle is on a sidewalk and then a person is about to ride it so an object at rest stayed at rest until the person rode the bike.Another example is when a pen is in a pencil case then I pick it up to use it so again this is a object stays at rest or util an unbalence force is opon the object

  11. Newtons first law states that something at rest seems to stay at rest and something that is moving seems to stay moving in a flat line up to when an outside force acts on it. One example is if a car is driving on the turnpike and the driver steps on the break stopping the car. Another example is if a stuffed animal is sitting on a table, it will not move unless someone or something moves it.

  12. Newton's first law explains that if an object is not moving that it will stay that way and if an object is in motion it will stay that way unless an unbalanced force changes its motion. One example would be during a soccor game. The ball is at rest, until one of the players kicks it. When the ball is kicked an unbalanced force is moving the ball towards the net. Another example could be throwing a football. The ball would be at rest in your hands, but when you throw it to a friend, an unbalanced force, which would be your arm, throws the ball to your friend. When the friend catches it, the football is at rest again.

  13. What Sir Isaac Newton’s first law is that an object at rest tends to stay at rest, while an object in motion continues motion in the same direction as motion. An example is when you positively accelerate in a car, you are forced into your seat and when you turn in a car, your body wants to go in the direction the car was going. Another example is when you flick a penny at a stack of pennies, the penny hit by the flicked penny moves while the pennies at rest stay at rest.

  14. Newton's first law of motion basically tells you that an object that is at rest will stay at rest until an unbalanced force moves that object. An example of this is when a soccer ball is sitting on the ground until somebody's foot comes along and kicks it. Newton's law also says that an object in motion will stay in motion until an unbalanced force comes along and either stops it or it is pushed away. An example is that a soccer ball is flying in the air until the goalie or somebody either kicks it away or pushes it away.

  15. Every body stays in a state of rest unless it is acted upon by an external unbalanced force. This means that in the absence of a non-zero net force, the center of mass of a body either remains at rest, or moves at a constant speed in a straight line.

  16. Sir Isaac Newton's Fisrt Law is called Inertia. Newton's first law states that an object that is still stays still, and an object in motion stays in motion unless an unbalanced force acts on it.For example, if you put a playing card on top of a cup and then put a penny on top of that playing card, and then you pull the playing card out from underneath the penny, the penny will drop to the bottom of the cup because of Newton’s First Law. Another example is when you ride your bike and you come to a sudden stop. When you reach that stop, your body will move forward. This is the same reason why you need to where a seat belt in a car.

  17. Sir Issac's Newton first law of motion is that an object at rest stays at rest and an object in motion stays in motion with the same speed and the same direction unless acted upon by a unbalanced force. An example of his first law is if you are in a car without your seatbelt, and say your going 85 miles per hour and you hits a wall, your body will fly out the seat hitting the windshield and IF the windshield breaks the person will fly out. Another example is if the head of a hammer can be tightened onto the wooden handle by banging the bottom of the handle against a hard surface.

  18. What I think Newton’s first law of motion means is that if an object is not moving, it will not start moving by itself. If an object is moving, it will not stop or change direction unless something pushes it. Two examples of Newton’s theory would be picking up an object, such as a piece of furniture, and moving it to another part of a room, or trying to stop something, like a car, from rolling down a hill by putting on the brakes or the car hitting something that would cause it to stop.

  19. Issac newtons first law was a body remains at rest or in motion with a constant velocity unless acted upon by an external force. 2 examples of this is when your are wearing a seatbelt and the car is stopped but your are stiil in motion but the seatbelt stops you. Another example is when your are running with a schoolbag on your back and you stop but the schoolbag can fly up over your shoulder.

  20. Sir Isaac Newton’s first law was the law of motion. This law is sometimes called the Law of Inertia. This law states that an object at rest tend to stay at rest, and an object at motion remains in motion with the same velocity, unless acted upon by an unbalanced force. One example is if a soccer ball is moving and another player kicks the ball, the velocity and direction changes. Another example is if the soccer ball is on the field and nobody kicks it, the soccer ball stays at rest.

  21. Newton's first law states that objects that are at rest, or objects that are still, tend to stay still, and an object in motion tends to stay in motion until acted upon by an unbalanced force. One example of Newton's first law would be you driving in a car at 60 miles per hour, when the car in front of you suddenly stops at a red light. You will continue to move at the same speed the car was moving until acted upon by an unbalanced force such as your seatbelt. This is the reason that you have to wear your seatbelt while in your car driving. Another example would be a glass on the table. The cup wouldn't move until someone or something moved it.

  22. In the mid-1600's an English scientist Sir Issac Newton studied the effects of forces on objects. He formulated three laws of motion that are still used today. Newton restated Galileo's conclusion as his first law of motion. Newton's First Law of Motion states that an object at rest stays at rest and an object in motion tends to stay in motion in a straight line until an outside force acts on it. This means unmoving objects stay still. A moving object moves in the same direction unless a force changes its motion. Newton's First Law is also called the Law of Inertia. For example, a person going in a car without a seatbelt, and the driver driving very fast, and then came to a sudden stop. Whoever is in the passenger side will hit the windshield, and the people in the back seat will hit the seat in front of them. Another example would be a football in the field, with nobody coming near to kick it. Since no force is taken upon the ball, it stays at rest, which Newton's First Law states.

  23. Newton's first law states that an object in motion stay in motion and an objects at rest stay at rest. An example of objects in motion could be a car going 15 mph. When at one point the car suddenly stops and if you don't have your seatbelt on you are going to fly out at 15 mph. An example for objects at rest could be a basketball on a rack. The basketball will not move unless acted upon an unbalanced force.

  24. Newton's first law states that objects can’t move by themselves. They have to be acted upon by an outside/unbalanced force to move or stop moving. An object that is stopped doesn’t move. An object that is moving doesn’t stop. An example of this is if Bob, Norm, Lenny, and Joe are playing baseball. Bob picks up the baseball (an object at rest) pitches his fastball to Norm,(an object in motion) who hits it to Lenny,(change in direction) who catches it and then throws it to the cutoff (Joe). There are many changes of direction in this example.

  25. Newton’s first law states that objects in motion stay in motion and objects at rest stay at rest. This law is sometimes called the law of inertia. One example is when a ball is sitting on the floor of a car, and the car suddenly turns left. The ball moves in the opposite direction because it wanted to keep going in the same direction as it was before. Another example is if a soccer ball is just sitting in the field, but no one has kicked it, the ball will remain at rest.

  26. Newton's First Law is that an object in motion tends to say in motion and an object at rest tends stay at rest unless acted upon by an ouside, unbalanced force. One example is when people are sitting in a car. If you don't have your seatbelt on in a car and the car makes a sudden stop, then you will go forward. This is because your body is still in motion even though the car made a stop. Objects like to keep doing what they're doing and in this case your body wants to keep going forward. This is because of Inertia. Sir Isaac Newton's first law of motion is sometimes called the Law of Inertia. A second example could be of a pencil. If a pencil is lying at rest on a desk, then it would stay there unless moved by an unbalanced force. In this case, it would be a hand picking up the pencil to use it.

  27. Isaac Newton’s first law is the law of motion which is sometimes called the law of inertia. This law states that an object in motion tends to stay in motion and an object at rest tends to stay at rest unless acted upon by an unbalanced force. One example is if you were driving a car without a seatbelt at 60 miles per hour and you suddenly stopped you would fly out the window at 60 miles per hour. Another example of Newton’s law is if you had a soccer ball it would be at rest until your foot (the unbalanced force) kicked the ball and would become an object in motion.

  28. Newton's first law of motion says that if an object is moving then it stays moving and if an object is still, then it stays still. The first example of this is if a soccer ball is still on the soccer field then it will stay still until someone applies an unbalanced force to it. The second example would be if someone was dribbling a soccer ball down field, and they stop dribbling to wind up to shoot it, the ball keeps moving until you shoot it.

  29. Newton’s first law of motion is that an object at rest stays at rest, and an object in motion stays in motion with the same direction and same speed unless something pushes it. An example of Newton’s first law is if you are playing a game of catch. Another example is if you are riding a bike and you come to a sudden stop, our body jerks forward.

  30. Isaac Newton's first law,the law of motion, was that an object at rest tends to stay at rest, and a object at motion tends to stay in motion. An example of this law is; A baseball is thrown by the pitcher, to the batter and the batter hits the ball. Another example of this law is; A book is left on a girl's desk at school overnight.

  31. Isaac Newton's first law of motion stated that an object at rest will stay at rest and an object in motion will stay in motion unless and outside force acts on it. For example, if a soccer ball is laying on the ground and someone picks it up. The ball would move because and outside force has acted on it. Another example would be if a pitcher threw the ball at the hitter and the hitter hit the ball into the air. The ball was in a straight path until the hitter hit the ball in another directio.

  32. Newton's First Law is that an object in motion tends to say in motion and an object at rest tends stay at rest unless acted upon by an ouside, unbalanced force. An example is if a car is going at about 70 mph and a car comes racing through you have to make a sudden stop, when you do this if you do not have your seatbelt on you will go flying out the windshield at that same speed.

  33. Newton's first law states that an object in motion will stay in motion and an object at rest will stay at rest unless exposed to an outside force. For example, a ball that is sitting on the ground will remain at rest unless an outside force causes it to move. Another example of Newton's first law is the earth which is constantly moving and will not stop unless an outside force acts upon it.

  34. Newton's first law says that an object in motion stays in motion and an object at rest stays at rest. Examples are when the car suddenly stops you move forward. Another example is when you have a volleyball in your hand its at rest but when your other hand hits it off its in motion.

  35. Newton says that an object that is still will remain still unless acted upon by an outside "unbalanced" force. A toy car will not move until you push it. A ball will not fall off a table unless gravity pulls it down.

  36. Sir Isaac Newton's first law was (Inertia) any object in motion stays in the state of motion and any object at rest stays in the state of rest. Also 2 examples of Newton's law could be example #1.) If you push the pedal of the car your accelerating and changing the motion of the car and if you go at a high speed and out of no where it the breaks your body is still moving and will go the same direction the car was going in, and you will fly out of the car, and that's why it's always important to wear your seat belt. Example #2.) If I were going to pick up a basketball I'd be changing the motion of an object, but then if I just drop it gravity will bring it back down to the ground and those where two examples of Sir Isaac Newton's first law Inertia.

  37. Newtons first law is objects still tend to stay still and objects that are moving tend to stay moving unless an unbalanced force is acted upon it. One example is kicking a soccer ball friction eventually stops the ball. The second example is riding a bike if you stop pedaling the bike will again stop overtime.

  38. Newton's First Law of Motion states an object at rest tends to stay at rest and an object in motion tends to stay in motion in a straight line, until an outside force acts upon it. One example of this would be a soccer ball sitting at rest on a field. Then a player comes along and kicks it. The player is the outside force causing the ball to move. Another example would be a player stopping a moving soccer ball. The ball is in motion until a player stops it with his foot. The player is the outside force acting on the ball causing it to stop.

  39. Newton's first law states an object at rest tends to stay at rest and an object in motion tends to stay in motion in a straight line until an outside force acts on it. For example, if a hockey puck was on the ice staying still and someone hit it with a hockey stick. The puck would move because because an outside force has acted on it. Another example is if a pictcher threw a ball at you and you hit it with a bat into the air. The ball was in a straight path until the I hit the ball in another direction.

  40. Newton's first law is an object in motion stays in motion and an object at rest stays at rest unless an unbalanced force is occured. Two examples would be a soccer ball on a field,the soccer ball will stay at rest unless an unbalanced force is applied on it which means if a person were to kick the ball it would not be an object at rest it would be an object in motion. Another example would be a person in a car if the car were to stop suddenly and the person wasn't wearing their seat belt they would keep going an object in motion stays in motion.

  41. Newton's 1st law declared that if a force is acted upon,it will slow down.(Like a contact force with the wheels & the ground)The Greeks thought that you needed a force to move an obect and not putting force on it will result in it stopping.

    In my words the law of motion means when an object is in motion it stays in motion until a force stops it. If a soccerball is in motion the force of someone else will eventually stop it. If a biker is going down the street and hits a large stone the biker will fall off the bike and he will stop when he hits the floor of the ground.

  43. Newton's First Law of Motion states that an object in motion stays in motion and an object at rest stays at rest unless an unbalanced force is put on the object. An example can be when a soccer ball is at rest until an unbalanced force is acted upon it by a person's foot. The soccer ball moves because an outside force is being put on it.

  44. Isaac Newton's first law was an object at rest stays at rest and a object in motion stays in motion. For example if soccer ball sitting on a field, this ball willbstay there until someone runs up and kicks it. The same thing occurs with an object in motion. If a puck is sliding o n ice itvwill keeps sliding until it is stopped by a force like wall.

  45. Sir Isaac Newton’s first law of motion or the law of inertia states that an object at rest tends to stay at rest and an object at motion tends to stay at motion until an unbalanced force applies force to it. One example of this is if a baseball is hit it will keep going until the centerfielder hops onto the wall and catches it with his glove or an unbalanced force. A second example of Newton’s first law is when a hockey puck is hit a hockey stick and it skims on the ice all the way to the net when the goalie hits it with his stick or the unbalanced force.

  46. Newtons First Law states that an object that is at rest stays at rest but if it is in motion it will stay in motion. For example say if a ball is still it will stay stil unless someone moves it. And if a runner is running it will keep onm going until he/she gets to the finish line.

  47. Newton's first law says that objects at rest tend to stay at rest and objects in motion tend to stay in motion unless acted upon by an unbalanced force. If a book is laying on a desk with no motion, it wil stay on the desk and will not move. A soccer ball will stay in the air unless a force acts upon it and changes its motion.

  48. Newton's first law of motion says that an object at rest remains at rest. An object in motion stays in motion unless an outisde force acts upon it. One example is that if you a hockey puck is resting on the ice it will not move until it comes in contact with a hockey stick. Another example would be a baseball is in motion until it is hit by a bat or caught by a glove.

Another example is if a hockey puck is resting on the ice it won't move unless a hockey stick moves it.

    Newton's law says that an object in motion stays in motion. When an object is at rest stays in rest. An example is if you have a basketball on a cart with no sides it is luckily to fall off when you turn the cart. Another example is if you are in a car and you make a turn your body will keep moving straight, but the will continue to turn. This is what I think of Newton's law and what it maens to me.

  51. I believe that Sir Isaac Newton's first law of motion says that objects at rest tend to stay at rest because objects have a tendency to keep doing what they are doing. On the other hand, objects in motion stay in motion with the same velocity unless acted upon by an unbalanced force. An example of the first law of motion would be a ball lying on the floor of a car would roll to the right if the car was turning left. Another example would be a person who was not wearing a seat belt would fly through the windshield if the fast moving car they were in stopped suddenly.

  52. To me Newton's first law is saying that when an object is at rest, it stays at rest until a force is acted upon it. An example are if you were a goal tender in soccer, you would stop the ball with your hands so it is at rest. Another example would be if you caught a baseball it would be at rest and it would stay at rest.

  53. Newton states that an object at rest usually stays at rest and an object in motion stays in motion until acted upon by an unbalanced force. The first example is, when you pick up a marker to use it, you are changing the position of the marker, so you are putting an unbalanced force on it. The next example is like when you kick a soccer ball, it flys up in the air, so you are putting an unbalanced force on it.

  54. Newton's first law states that an object in motion stays in motion and an object at rest stays at rest unless acted upon by an unbalanced force. This basically means that an object will continue doing what it is doing unless changed by an outside force. Newton says this is the resistance of an object to change motion. This resistance is called inertia. The first law is also called the Law of Inertia. Here are two examples. One is when you are driving a car and suddenly make a turn. You feel your body going straight, even though you are turning. Another example is kicking a still soccer ball, changing the motion

  55. Newton's first law says that "an object in motion tends to stay in motion and an object at rest tends to stay in rest" what this means is that when a object is moving it will keep moving and when an object is not moving it will stay still examples of this are a kicker kicking a football for a fieldgoal or a defender blocking a pass from the quarterback
