Let's review a bit of physics in preparation for Part 2 of our technology transfer series on page 28. All elements in a rotating body have a measure of kinetic energy. Simply stated, this is "energy ...

If you’ve ever played with tops, you know that some spin easily while others wobble. Ever wonder why? The answer has to do with rotational inertia, a property shared by all rotating systems. Sometimes ...

Diving is among the most popular spectator events in the Olympics, a graceful sport that combines elements of gymnastics and dancing. It’s also an excellent example of physics in action. Let’s look at ...

Every dazzling jump on the ice—like Yuzuru Hanyu's quadruple Lutz at the 2017 Grand Prix of Figure Skating in Moscow, Russia—requires a mastery of balance, rotational speed and angular momentum. Aflo ...

The case of a pulsating-load testing machine shows how to ballpark qualities that are important for deploying electric motors. Crankshafts in running internal-combustion engines pulsate as well as ...
