Why study physics, you ask? Scroll down, friend. This video of a guy rolling through a 360-degree vertical loop at a skatepark—cool as ice, with no helmet—is answer enough. Clearly, his understanding ...

We solve for centripetal acceleration, centripetal force, and tangential velocity. In this Closer Look segment on circular motion, we investigate circular motion and solve for centripetal acceleration ...

Physicists have created a new type of time crystal that may help confirm some fundamental theories about quantum interactions. A standard time crystal is a new phase of matter that features perpetual ...
