Copyright © Restrictions by Ron Kurtus (revised 6 August 2013) Newton's Cradle is a clever device that uses a series of equal pendulums in a row to demonstrate the Laws of Conservation of Momentum and Conservation of Energy. By pulling one ball away from the others and releasing it, the ball will swing and strike the second ball, which in turns sends the momentum through the series of balls causing the last ball to move away from the group. This device is often used for demonstrations in the classroom, as well as a toy to amuse people. Questions you may have include: What is a description of Newton's Cradle?
