====== JOINT POWER SCALAR ======

||

Joint Power is a scalar term computed at:

Power = [Mx,My,Mz] . [wx ,wy,wz]\\
Power = Mx.wx + My.wy + Mz.wz

\\
but it has become common in the biomechanics community to resolve Power into a [[Visual3D:Documentation:Pipeline:Model_Based_Data_Commands:JOINT_POWER|segment coordinate system]].

**Joint Power requires a "Joint" to be created because Joint Angular Velocity is the relative angular velocity between the two segments intersected by the Joint.**
