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 ...

Brian Greene: When we talk about vibration in physics, we have an interesting set of equations, mathematical equations that govern how a system vibrates.So if we have a string on a violin, we have ...

In this case, you can see the whole motion (again, this is slow motion 240 frames per second). I'm not going to get an exact measurement (that can be one of your homework questions), but it seems ...

The propagation of light is explained by Maxwell’s equations. Although he worked them out in the 19th century, they are consistent with both relativity and quantum mechanics. This question ...

Unfortunately, thanks to the fundamental physics of our universe, perpetual motion machines are impossible. Now, I know that there are probably a lot of people who are saying, ...

Perpetual motion—it's fun to say that. For some people, perpetual motion machines hold the secret to everlasting free energy that will save the world. To them, it's a machine that is just beyond ...
