# How does torque differ from work?

Jun 7, 2015

Torque is the counterpart of force in rotational mechanics.
Both are sort of "forces" in common language but, the basic difference is that torque is the ability of a force to produce a twist around an axis.

Now, let us come to work.
It is defined as,

$W = F \cdot d C o s \theta$
where $F$ is the magnitude of force, $d$ is the displacement and $\theta$ is the angle between the two vectors.

Similarly, work is done by a torque too where we have to consider the angular displacement in place of displacement.
