THe joy of physics
Its the motion from any change in momentum of the rotating mass. Think of the tail rotor on a helicopter. Unless there are twin counter-rotating blades the turning torque of the motor would spin the bird w/o the tail rotor. Trammel bars are used on 60 mucsle cars to overcome this force being transfered to the tires.
