question archive Which is NOT true about rotational motion? a) If rotating object is isolated from external forces and moment of inertia of object increases, the angular velocity will decrease b) a mass moving with constant tangential velocity in a circle with radius r has smaller centripetal acceleration than the same mass moving at same tangential velocity in circle with radius 2r c) there can be force acting on object but no torque d) angular momentum of object changes in time if torque is applied to it e) if tangential force is applied to the rim of bike wheel, then there will be torque on the wheel f) all true
