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.
