Answer:

To have a positive job, the two vectors must have the same direction

Step-by-step explanation:

Work is a scalar defined as the scalar product of two vectors, the froce and the displacement. To have a positive job, the two vectors must have

collinear and that their arrows point in the same direction.

You can also appreciate this from the work equation

W = F. r

bold indicate vector

W = F r cos θ

With θ the angle between force and displacement
