The work-energy theorem states that the change in

kinetic energy of a particle is equal to the work done on it by the net force
kinetic energy of a particle is equal to the work done by one of the forces acting on it
potential energy of a particle is equal to the work done on it by the net force
potential energy of a particle is equal to the work done by one of the forces acting on it
total energy of a particle is equal to the work done on it by the net force

Solution:

According to work-energy theorem, change in kinetic energy of a particle is equal to the work done on it by the net force., i.e.

W = F \cdot S = \; \frac{1}{2} m v^{2}
