Second Law

| View Cart ⇗ | Info

An illustration of what it would look like if ball e that is placed in a cup attached to lever o were to be pushed out by using a swinging arm activated by spring d. Spring d is arranged in a manner that when it is drawn back and released, it will strive lever o and ball b at the same time. In the experiment, ball b follows the curved line and ball e is dropped vertically. Both will meet the floor at the same time. This experiment is meant to show how Newton’s second law works. The acceleration of a body is parallel and directly proportional to the net force and inversely proportional to the mass. F = ma
