4.The work done by a
centripetal force acting on an object moving at a constant linear speed is:
I. zero because the centripetal force is perpendicular to the displacement of the object. II. not zero because a force acts on the object and the object moves III. not zero because energy is required to turn an object IV. zero because the object is moving with constant speed
Definition Definition Force on a body along the radial direction. Centripetal force is responsible for the circular motion of a body. The magnitude of centripetal force is given by F C = m v 2 r m = mass of the body in the circular motion v = tangential velocity of the body r = radius of the circular path
