Description

This is an exclusive! You won’t find this unique Newton’s cradle with Z-rail suspension and alloy metal silver base anywhere else.

Newton’s Cradle is a device that demonstrates conservation of momentum and energy. Pull back 1 or more of the balls and let them drop down. The same number of balls will swing up on the opposite side and the clicking will go back and forth until it stops.

  • Comes with a Teacher’s Guide
  • Custom made packaging ensures the product arrives tangle-free
  • Packaged in a colorful retail box
  • Approx. 0.75″ (19 mm) solid steel balls

Observe the affect of momentum with this familiar desk toy. Five balls touch sides while hanging suspended from two wires, each of the same length. When one ball is pulled back and dropped, it impacts the ball next to it and magically forces the ball on the other end to bounce away from the others with the same height and speed as the first was dropped. In objects too stable to be moved, waves of the impact travel through them, allowing momentum to continue until friction reduces it, or the source of energy is lost. The middle balls seem to be still, (though they are transferring momentum through shock waves.) The opposite end ball mimics the first, as the momentum traveled through to it and now it can rise and fall with seemingly the same momentum and height. (A slight difference will exist, though may not be noticeable yet, due to friction.)

To comprehend how this works, consider Newton’s Laws, friction, and shock waves.

Newton’s three laws:

  • Items tend to keep doing what they are doing. If they are stopped, they stay stopped, and if they are moving, they will continue to move. (Also called the Law of Inertia.)
  • Force is Mass multiplied by acceleration. (The heavier and faster the object that hits you, the more you’ll feel it.)
  • For every action, there is an equal and opposite reaction. (If you throw a stone in a pond, the stone goes in and causes ripples to go out.)
