SUMMARY
Torque and force are fundamentally different concepts in physics, despite both being involved in motion. Torque, represented by the symbol τ, is associated with rotational motion and has the same units as energy, specifically joules per radian. This relationship arises from the equations for work done in translational motion, E = ∫Fdx, and in rotational motion, E = ∫τ dθ. Understanding this distinction is crucial for accurately applying these concepts in physics.
