Answer the following question given this paragraph: 

How the Work-Energy Theorem Applies Now let us consider what form the work-energy theorem takes when both conservative and nonconservative forces act. We will see that the work done by nonconservative forces equals the change in the mechanical energy of a system. As noted in Kinetic Energy and the Work-Energy Theorem, the work-energy theorem states that the net work on a system equals the change in its kinetic energy, or W net = ΔKE . The net work is the sum of the work by nonconservative forces plus the work by conservative forces. That is,.


Q: The work-energy theorem states that the net work on a system equals the change in what type of energy?

 Choices:

- binary energy

- new energy

- residual energy

- kinetic energy

A:
kinetic energy
