Work Energy Theorem

Concept Card: Work-Energy Theorem for Constant & Variable Forces 1. Statement & Universal Scope of the Work-Energy Theorem (WET): The net work done by all external and internal forces acting on a body (or system of bodies) equals the total change in its kinetic energy: $$\mathbf{W_{\text{net}} = \Delta K = K_f – K_i = \frac{1}{2}m … Read more
