The work-energy theorem states that the work done by all forces acting on a particle equals the change in the particle’s kinetic energy.

Work is said to be done when an acting force displaces a particle. If there is no displacement, there is no work done. You might get tired if you keep standing for a long time, but according to Physics, you have done zero work.
Thus, work is a result of force and the resulting displacement. Now, we already know that all moving objects have kinetic energy. So, there must be a relation between Work and kinetic energy. This relation between the kinetic energy of an object and work done is called “Work-Energy Theorem” .
