The work-energy theorem relates the net work done on a system to a change in which quantity?

1. The work-energy theorem states that the net work on a system equals the change in the quantity one half m v squared. 2. That quantity, one half m v squared, is defined as the translational kinetic energy of the system. 3. Momentum and angular velocity are different physical quantities, each with their own separate relationships to force and torque, not to net work directly. 4. Gravitational potential energy is a separate quantity tied to height, not to the net work-kinetic energy relationship stated by this theorem. _Source: OpenStax College Physics (CC BY 4.0), Ch 7 "Work, Energy, and Energy Resources", section 7.2 Kinetic Energy and the Work-Energy Theorem_
