See below.

Explanation:

The work W done by the force F along a displacement s along a straight line is given by:

W=Fs

As energy is tightly related to work, where E_k is the kinetic energy of a body, we say:

W=DeltaE_k

On the other hand, where E_p is the potential energy of a body, we say:

W=-DeltaE_p

If work is done on an incline, where theta is the angle of inclination, we say:

W=Fscostheta
