You’ve probably seen Newton’s Cradle at an office. It could be at your doctor’s clinic while you're waiting for the lab test results. It could be at a law firm when you had to wait a long, long, long time before you talked to someone. Or it was on your dad’s desk in the ’90s.
Newton’s cradle (a.k.a. Newton’s pendulum) is five metal balls lined up perfectly and suspended by strings. All of these are connected to a metallic frame. When you pull the ball at the end and release it, it falls back and collides with the others. This action creates a continuous motion among the five balls.
However, once the end ball hits the others, it doesn’t show that they are all in motion. Only the ball on the opposite end jumps forward leaving the others perfectly still. The motion continues until the energy is used up. Slowly, the motion comes to a stop.
So, why is it a popular decoration in the offices? Well, watching the balls are kind of relaxing. Plus, it’s a cool way to kill some time, but it’s even a cooler way of demonstrating the three main physics principles at work: conservation of energy, conservation of momentum and friction.
Need more info? Here’s a quick video of Bill Nye explaining Newton’s pendulum. You can also watch Mythbusters tackle the science behind the massive Newton’s cradle they’ve created. And for some ASMR, here’s a demonstration of a large Newton’s cradle. Enjoy!
