It was an ingenious experiment, but Michelson and Morley did not get the result they were expecting, over and over and over again.

Physics, particularly forces and motion, can be challenging. By observing everyday motion, conducting simple experiments, and understanding Newton's laws in plain language, the concepts become ...

Find out how forces and motion make our world move in the Science Trek: The Web Show.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

But what about experimental physics? Doing simulated experiments on a screen holed up in our bedrooms can surely never be an adequate substitute for the real thing? However, we think there are some ...

Preliminary results from two experiments suggest something could be wrong with the basic way physicists think the universe works, a prospect that has the field of particle physics both baffled and … ...

Cats twist and snakes slide, exploiting and negotiating physical laws. Scientists are figuring out how.

The UChicago experiment did just that with a combination of high- and low-tech instruments, including force sensors, laser sheets, X-rays, high-speed cameras taking images at 10,000 frames a second, ...

Why do things fall? It’s about force and motion. Find out more in this Science Trek short. A force is basically a push or a pull. Forces like gravity, inertia, and momentum affect everything. On ...
