Answer: The force is as a function of Distance
Explanation:
The force and distance must be parallel to each other. Only the component of the force in the same direction as the distance traveled does any work. Hence, if a force applied is perpendicular to the distance traveled, no work is done. The equation becomes force times distance times the cosine of the angle between them.
where both the force F and acceleration are vectors. This makes sense since both force and acceleration have a direction.
On the other hand, the kinetic energy
K=12mv2
looks completely different. It doesn't seem to depend on the direction.
