Rotational Motion Quiz

Euler's rotation theorem states that simultaneous rotation along a number of stationary axes at the same time is impossible; if two rotations are forced at the same time, a new axis of rotation will result.

Rotation around a fixed axis excludes the possibility of the instantaneous axis of rotation changing its orientation and cannot describe phenomena such as wobbling or precession.

The assumption is that the rotation is stable, such that no torque is required to keep it going.
