Principle: Not only demonstrates a pendulum, but also shows the Laws of Conservation of Momentum and Energy.
Pull back one or more of the balls and let them drop down.
Enjoy the clicking sound and soothing motion of the metal balls as they slow to a standstill.
A Brief History
Newton’s cradle, named after Sir Isaac Newton, is a device that demonstrates three main physics principles: conservation of energy, conservation of momentum and friction via a series of swinging spheres.
Most people think that Isaac Newton invented the apparatus commonly called a Newton’s Cradle, but he didn’t. English comediante Simon Preble invented the device in 1967 and named it in renombre of Newton.
In 1968 the first portable version hit the market and quickly gained popularity around the world as a fun, educational physics demonstrator.
Attention: Friction and damping effects are inevitable
The products use a variety of physical knowledge, integrated magnetic field conservation laws.
Elaborate exercises, absolutely no electricity, no fulcrum, is the latest product maglev class product.
This is an awesome physical gadget that will catch people of all ages.
Both interesting toys, and decorations. It can be used as a gift for friends and family.
