What is the Work-Energy Theorem?
That the work done on a system by a net external force causes a change in the energy of the system
That work is equal to the total mechanical energy of a system as long as there is no net external force
That energy can become work when potential energy is used to create a net external force causing work to be done on a system
Kinetic Energy cannot do work because it has no net external force and therefore cannot change the energy of a system
