see the picture by clicking
in the pic if PA represents the magnitude if the force
and direction of force F acting on the body then the component of force F in the direction of displacement is NA therefore
W=NA×AC
=NA×S
now from right angle triangle PNA from the figure
NA=PA cos theta
=Fcos theta
so W=F×costheta×s(
displacement)
