SUMMARY

Torque and work are fundamentally different despite having the same units. Torque (T) is defined as the vector product of the position vector (r) and force (F), expressed as T = r X F. In contrast, work (W) is a scalar quantity calculated as W = T * θ, where θ represents the angular distance in radians. This distinction highlights that while torque can produce rotation, work quantifies the energy transferred during that rotation.

I know that torque is a vector quantity, whereas work is scalar.

But, in terms of the distances, what makes torque and work different?

Thanks!

Torque (T) is a vector equal to r X F, where F is the force and r is the position vector (in length units) from a chosen point. When torque produces a rotation , theta, the work (W) done by that Torque is derived as W = T*(theta) (for constant torque and circular motion), where the angle theta, in radians, represents the angular 'distance' travelled. Work has no direction, but can be positive or negative. The units of work and torque are the same, but torque and work are not the same.
 
Thanks so much for the quick response -- that makes much more sense now.
