Answer:
When the direction of the force is parallel to the displacement of the object
Explanation:
The work done by a force when moving an object is given by:
[tex]W=Fd cos \theta[/tex]
where
F is the magnitude of the force
d is the displacement of the object
[tex]\theta[/tex] is the angle between the force's direction and the displacement
From the formula, we see that the work done is maximum when
[tex]cos \theta=1[/tex]
which occurs when
[tex]\theta=0^{\circ}[/tex]
so, when the force is parallel to the displacement.
