A body remains at rest or in motion with a constant velocity unless acted upon by an external force Newton's first law of motion • Or a body in motion stays in motion and a body at rest stays at rest unless acted upon by another force.
Centripetal force • Moving or directed toward a center or axis
Centrifugal force • Moving or directed away from a center or axis
Centrifical force • Not a word
