I do not think responses like this really add anything to the discussion at hand. If you wouldn't phrase it that way when talking to your grandmother, it probably isn't the way you want to say it on CD.
As others have said, it is certainly a physics concept and being able to explain the difference between centripetal and centrifugal force is a key indicator that you understand what a reference frame is, and how they work. In college, particularly in Orbital Mechanics or Mechanism design this intuitive understanding becomes very important as the vector math gets real crazy, real quick. Any good physics textbook should have a reasonably in depth explanation, an old
xkcd comic does a decent job in a blurb, and of course
Wikipedia goes into much more depth.
