WORK ENERGY THEOREM
... WORK ENERGY THEOREM According to the work-energy theorem, the net work on an object causes a change in the kinetic energy of the object. The formula for net work is net work = change in kinetic energy = final kinetic energy - initial kinetic energy. The work W done by the net force on a particle equ ...
