Work is equivalent to energy spent by us to displace a body.
If we do some work on a body its Kinetic energy increases, it means our work is in that body in the form of Kinetic energy. So it is scalar quantity.
Torque is the rotational analogue of force. In torque we want to know that to give the rotational effect how much force is needed and where and how that force must be applied.
Torque= force displacement sin?
