Work done = force x distance in the direction of the force

= ( ) : unit

But if the force F is applied at an angle,  the horizon line, the figure below,

the force F shall be decomposed into two components:

horizontal component : F kos 
vertical comoponent : F sin 

F sin 

F N
F cos 



S m

Hence;
=  ( ) : unit
