Universal Specialties Classic Newton's Cradle Extra Large 7 1/4 Inch Dark Brown Wooden Base Balance Balls
Newton's Cradle, also called Balance Balls, is a great desk and classroom science toy. This educational tool demonstrates the conservation of momentum and energy. Newton's first law of inertia - an object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted on by an external force. Newton's second law - Force = mass X acceleration. Newton's third law - For every action there is an opposite and equal reaction.
This desktop physics executive toy demonstrates conservation of momentum and energy. This device consists of 5 metal balls of equal mass. When 1 ball is lifted and released, the force travels through the remaining balls and causes a single ball on the other end to rise. Lift 2 balls and release and 2 balls on the other end will rise.
Whether you are a child, adult, student or teacher you will love this classic invention. Buy it for yourself or gift it to a friend.
