Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

That's because its direction is constantly changing to point to the center of the circular path — a condition that's defined as centripetal acceleration, as expressed in the equation here.

Centripetal force is the force needed to make something move in a circle. Well, maybe it would be better to say that centripetal force is the force needed to make something change direction.

Centripetal force: The force that keeps an object fixed in its circular path is the centripetal force. Moreover, this topic deals with the definition, example and formula of it.
