Question:

If you have an electric motor on a bench and hook it to the power the shaft turns. If you put the shaft in a vise the casing of the motor will turn.
Now:...put this motor in free space no gravity and attach a battery for power..when the power is turned on will the motor shaft turn? will the casing turn? What happens??? thanks
