Did you know that, at a certain point on a moving wheel... there's no motion? Did you know that, at a certain point on a moving wheel... there's no motion? I mean, kinda... it's all relative, right?

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 ...

Learn the key differences between centripetal and centrifugal forces, their real-world applications in physics, and how they shape our understanding of circular motion. When you purchase through links ...

The force exerted on a charge is always perpendicular to the velocity of the charge. The force exerted changes the velocity so the direction of the applied force changes as a result. Overall this ...
