Torks in Kinetics

A tork can be thought of as s the turning effect of a force so you can't have a tork unless you have a force. If an object's rotation motion changes, then a tork must have been the cause. How i end up doing an inverse dynamics analysis on the golf club is as follows: You track the motion of the club and use that to figure out what the golfer must be doing. So that's how that's help inversin amitors.
