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.
