NEWTON'S LAWS OF MOTION Name and draw a picture of a ride that uses each.

 

1. First Law of Motion:

A body remains at rest unless a force makes it move. A force is required to change the speed or direction of a moving body.

2. Second Law of Motion:

Acceleration of a body increases as the amount of force producing the acceleration increases. The larger the mass of the body, the larger the force needed to produce acceleration. (Force = Mass x Acceleration)

3. Third Law of Motion:

For every force, there is an equal and opposite force.

(The two forces that always act together are called action force and reaction force.)

Centripetal force is a force that keeps a body in a curved path. It acts toward the center of the curve.
