Without a centripetal force, an object in motion continues along a straight-line path. With a centripetal force, an object in motion will be accelerated and change its direction.

Relationships Between Angular and Linear Quantities Tangential Speed - the instantaneous linear speed of an object directed along the tangent to the object’s circular path.
