Explanation:
The work done by an object is given by :
[tex]W=Fd\cos \theta[/tex]
Here,
F is force
d is displacement
[tex]\theta[/tex] is the angel between F and d.
If the angle between force and displacement is 0, then the work done is equal to, [tex]W=Fd[/tex].
So, a force does work on an object if a component of the force is parallel to the displacement of the object.
