    Q:

    		 If a nonzero net torque is applied from an external source onto a frictionless rotating device, which of the following statements is false?
    		 

    A

    		 The rotational velocity at some time t can be equal to zero after the torque begins.

    B

    		 The final total rotational energy of the system can be greater than the total work done by the net torque.

    C

    		 The total momentum of the device is constant before and after the torque is applied.

    D

    		 Any gravitational potential energy gained by the device during rotation is lost upon completion of a full revolution.
