In this video, we solve a classic AP Physics 1 ramp to projectile motion problem step by step, showing how energy, kinematics, and motion concepts connect. Ideal for exam prep and for students looking ...

Perhaps the most persistent nonsense in physics: the perpetual motion machine. Bad ideas come and go in physics. But there’s one bit of nonsense that is perhaps more persistent than all others: the ...

Isaac Newton would never have discovered the laws of motion had he studied only cats. Suppose you hold a cat, stomach up, and drop it from a second-story window. If a cat is simply a mechanical system ...

How do skateboarders seemingly defy gravity? How do gymnasts flip in the air? They have skill — and, as a Times interactive explored, an understanding of the laws of motion, physics and energy. By ...

The constant, energy-driven motion inside living cells may generate electricity in a way no one fully recognized before.

This article was originally featured on Knowable Magazine. Isaac Newton would never have discovered the laws of motion had he studied only cats. Suppose you hold a cat, stomach up, and drop it from a ...
