Why centrifugal force is called pseudo-force?
Why centrifugal force is called pseudo-force? The centrifugal force is a pseudo-force because if the centripetal force ceased for an object in circular motion, the centrifugal force the body is “feeling” would instantly disappear, and the object would travel tangentially to its line of motion. Can centrifugal force overcome gravity? The centrifugal force is real […]
