work Definition
we can says work is the product of magnitude of displacement and component of force in the direction of displacement.
Explanation
Let us consider an object which is being pulled by content force F at angle theta to the direction of motion.The force F moves the object from position A to B through displacement D as shown in figure.
Now by definition work is given by.
where,
F Cos 0 is component of force in the direction of displacement.

W = (F cos 0) (d)
= Fd cos 0where,
F Cos 0 is component of force in the direction of displacement.
