The First Law
The first law says that an object at rest tends to stay at rest, and an object in motion tends to stay in motion, with the same direction and speed. Motion (or lack of motion) cannot change without an unbalanced force acting.

Newton's cradle demonstrates the third law of motion. When one of the balls is lifted and released, it strikes the remaining stationary balls and sends force through all of them to push the ball on the other end away. |
