Rotational Kinetic Energy
... The quantity torque is that which causes a rigid body to have a rotational acceleration about some axis. In order to give a rigid body a rotational acceleration, it is clear that one has to exert a force. However, where the force is applied makes a difference. If applies a force whose line of action ...
