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 ...

If the angular velocity of a link in a mechanism is zero, does this imply that the angular acceleration of that link is also zero? The short answer to that question is NO. If ω(t) represents the ...

Introduction You might have seen figure skaters spinning around quickly and then tucking their arms to spin faster—or opening them to spin more slowly. This happens, thanks to a physics concept known ...

For instance, once a skater leaps into the air, they’re stuck with however much angular momentum they’ve created. But a ...

Diving has gotten a lot of strange attention this year, thanks to a lack of filtration chemicals that caused the water to turn from a pristine blue to a worrisome green, which Olympic officials are ...
