You're sitting in physics class, working on a traditional problem involving forces and acceleration, when you start to wonder where these terms even came from. Were they just dreamed up to bring ...

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 more ...

Find out how forces and motion make our world move in the Science Trek: The Web Show. The world is full of motion and motion happens because of force. On this episode of Science Trek: The Web Show, ...

The weak nuclear force doesn't play by the normal rules — and, in fact, it breaks one of the biggest rules of all.

Tugging a small toy with your dog can be a lot of fun—but it’s also a great way to experiment with forces acting on an object. Forces are what scientists call the pushing and pulling on objects. In ...

Second Life is an online world in which people use avatars to explore and interact with each other and to build more or less anything based on simple geometric shapes. These objects are governed by a ...

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 ...

Some of the most difficult (and most important) experiments in the history of physics had to do with making connections between different concepts. What about the connection between objects moving ...

On July 5, underneath the suburbs of Geneva, Switzerland, the world’s largest particle collider will fire up and start collecting data again. And what they might find has the potential to blow ...

Physics, especially the part about forces and motion, often feels like a maze of confusing concepts and formulas. If you’ve ever stared at a problem about an object moving or a force acting and ...
