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#
