Product Description
Named after Sir Isaac Newton, this is a device that demonstrates conservation of momentum and energy via a series of swinging spheres. When the ball on one end is pulled aside and allowed to swing as a pendulum, it hits the next ball, knocking the end ball away from the others with the same speed as the first ball had initially hit it and leaving the remaining balls nearly at rest.
This is a great executive gift or for the child who is interested in physics.
