When we studied the concept of work, we learned that work = force x distance. Now we learn that torque = force x distance. What's different about these two definitions?A) For work, distance and force are in the same direction; for torque they are perpendicular to each other.B) For work, the force must be against gravity, while for torque, not so.C) The units of distance are different for work and torque.D) Actually the two definitions are the same. Only the applications of them differ.E) Work is measured in joules, and torque is measured in pseudo-joules.
