Both "the work done by a force" and "the torque produced by a force" are the product of force and the position vector. how can one make the difference between the two? explain.

 Answer: Work done = Force x Distance and Torque = Force x perpendicular distance i.e. both work done and torque both are defined as the product of force and position vector or distance. however work done is dot product and torque is vector product i.e. work done is scalar quantity and torque is vector quantity. This is the main difference between work done and torque.
