Description
Pull one of the metal balls to the side, release it, and be mesmerized by the back and forth play of the balls. .
The ball's positional energy is transferred to kinetic energy which strikes through the chain of balls and gives the ball on impact energy through the chain of balls and gives the ball at the other end kinetic energy to bounce out accordingly. This is how Newton's cradle swings back and forth.
