MEYALL Newton’s Cradle Balance Balls, Art in Motion Toys for Kids Adults, Science Physic Psychology Educational Kits (Medium Size)

History of Newton’s Cradle:
Newton’s cradle (also known as Newton’s balls or Executive Ball Clicker), named after English 17th century scientist Isaac Newton, is a device that demonstrates conservation of momentum and energy using a series of swinging spheres.
When one sphere at the end is lifted and released, it strikes the stationary spheres; a force is transmitted through the stationary spheres and pushes the last sphere upward.

Newton’s Laws of Motion: “For every action there is an equal and opposite re-action.”
Fine argument of Newton’s law of motion and the starting point of physics. Inspired us to better understand the concept of conservation of momentum. Demonstrates Conservation of mechanical energy.

Newton Cradle will never be outdated. It’s great for physical teachers, students, office workers, kids, men and women at all ages.
