No. Imagine you're floating is space, if you twist something you can't help twisting yourself in the opposite direction so that the total AM of you and thing you twisted is the same as it was before you twisted it. You both then have have kinetic energy where you didn't before, but your total AM hasn't changed. If you are in friction with the thing you twisted then eventually you and the object will no longer be spinning relative to each other, all the kinetic energy will be disapated as heat. The total AM will not have changed throughout. If you think it would have changed, which direction do you think it would have changed in? Regards, Mike.
