Re: Torque?
I teach my conceptual physics students that torque is a twisting force, one that may cause rotation.
Pushing with a force inward on the end of a door produces no rotation, but the same force exerted on the face of the door may make the door move.
In AP Physics we discuss the mass distribution of the object being rotated, how the moment of inertia will affect the angular acceleration, etc. Little more tricky, but way more fun.
