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 ...

Centripetal force is the real inward pull that keeps objects moving in circles, while centrifugal force is the apparent outward push we only feel in rotation.

New Scientist Book Club has been reading Alex Foster’s debut novel, Circular Motion, in which he charts what would happen if Earth’s rotation sped up by not just a millisecond, but a minute, or an ...
