Named after Sir Isaac Newton and his Third Law of Motion, Newton’s Cradle is an instant classic that’s sure to provide a valuable glimpse into the world of physics in a way that’s sure to grab the attention.
When a ball on one end of the cradle is pulled away from the others and then released, it strikes the next ball in the cradle, which remains motionless. But the ball on the opposite end of the row is thrown into the air, then swings back to strike the other balls, starting the chain reaction again in reverse.
