Calculate the work done if a 25N force acting in a direction of vector (2,3,-1) moves an object from P(2,-3,1) to Q(5,0,2).

2. Relevant equations

Work = Force (dot) Displacement

3. The attempt at a solution

Well force is 25N. But as for displacement, do I just find the displacement of the points P and Q, but then whats the direction vector (2,3,-1) for? I'm just a bit confused on this.
