Centripetal and centrifugal forces are central to circular motion, but they're not the same. Discover the differences between ...

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, ...

I saw it again. This time it was an introduction to an interesting online look at introductory physics. I was excited---but then, I wasn't so excited. Right there in the first video they talked about ...

This week Shini sits down with us to discuss centripetal force, centrifugal force, and a few other bits of physics to help us understand Uniform Circular motion. Crash Course Physics is available to ...

A recent astronomical discovery has left scientists puzzled as they track an object accelerating in a manner that defies the current understanding of physics. This enigmatic object, potentially ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the ...
