NEWTON'S THREE LAWS OF MOTION

Newton's First Law

• An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force

This picture represents Newton's First Law by showing that it can be acted on by an unbalanced force. The unbalanced force that would act on this object would be wind. The object will catch the wind, causing itself to rotate its segments. This shows motion. The object will allow itself to be controlled by an unbalanced force.

This picture represents Newton's First Law by also showing that it can be acted on by an unbalanced force. The unbalanced force here would be picking up the fork. When the fork is set, it is balanced. Therefore, moving the fork to another place would be an unbalanced force. Also, unbalanced forces acting the fork could be the fork stopping.

Newton's Second Law

• The acceleration of an object depends on the mass of the object and the amount of force applied

This picture of the train represents Newton's Second Law by showing that more force can accelerate it. If the train had less force added, it would decelerate. If it had more force, it would accelerate. This train would be hard to accelerate because it has a large amount of mass. To conquer this issue, you would have to add more force.

This picture portrays Newton's Second law by showing that force can be used to throw a football. The amount of force depends on how fast the ball will go. Depending on the strength of the receiver, the ball will either push him back or he will catch it moving forward. This outcome will also depend on the force of the thrower. The ball will, once again, either push back the receiver or drop in front of the receiver.

Newton's Third Law

• Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.

This picture represents Newton's Third Law by showing the objects in it will have an action and reaction. The action is hitting one of the dominos toward the others. This will cause all of the other dominos to fall. This would be the reaction. Also, the harder you hit the first domino, the faster the others will fall.

This picture portrays Newton's Third Law by showing the object can have an action and reaction. The action in the picture would be pulling the arrow back. The reaction is the arrow hitting a target at a high speed. The farther the arrow is pulled back, the farther the arrow will go. This is true because there is more force to be exerted the farther the arrow is pulled back.
