This crazy parkour move, where a guy bounds up between two walls by jumping from one to the other, is based on the momentum principle and friction.

The spring inside a clicky pen is a perfect way to learn about projectile motion.

There’s no fooling gravity—but this trick makes it look like you can.

Frame-by-frame video analysis shows an illegal forward pass—but in the reference frame of the QB, it's backward.

In normal water, a human just barely floats. But the *Stranger Things* kids know a workaround.

You can use angular momentum to describe everything from fidget spinners to back flips to interstellar asteroids. Let's see how it works.

We're not saying this interstellar object is a spaceship. But it sure would make for some cool physics.

Really, Thanksgiving is all about thermal transfer.

Elon Musk already has a whole company devoted to solar energy—why not just combine and conquer?

You could climb out of a hole with a ladder or a rope—or you could call on your formidable physics knowledge.
