Question

what is difference between work nd torque?

Answer 1

Units of work Joule or Newton-metre

But the unit of torque is Newton-metre

We never express Joule as the unit of Torque.This is the first striking difference we notice.

If we go deeper Work is the amount of energy spent to move an object to a particular distance in the same direction of force applied,

i.e is the dot product of Force applied and distance covered.It dont have particular direction.Hence it is the scalar quantity.

Torque is the vector quantity. It is the cross product of Force and distance.

Here the distance figure doesn't tell you anything about how much work the torque does, because that distance figure is perpendicular to the motion, not in the same direction as the motion, and the dot product of that distance and that motion is 0.

There will be an torque angle always between force and distance which at 90 degrees gives maximum torque.
