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 ...

Learn where the centripetal acceleration formula comes from with a clear, step-by-step derivation. This video explains circular motion, velocity direction changes, and the physics behind the equation, ...

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 ...

Segment 3G: Circular Motion We explore the concept of circular motion. Segment 3G: Circular Motion We travel to an amusement park to explore circular motion. We work through an example problem and ...
