NEWTONS FIRST LAW OF MOTION describes why objects continue moving or staying still unless an unbalanced force is acted upon it. An example of his first law is a hand stopping a ball after going down a ramp.
A ball that is rolling down a ramp is moving, but an unbalanced force which is the hand stops the ball which is an example of Newton's first law because an object is moving but an unbalanced force is acted upon it making it stop.
