## Homework Statement

An object of mass 100kg is acted on by a constant force as it moves through a displacement at a constant speed of 7.2m/s. What is the net work done on the object?

## Homework Equations

Wnet = ΔK

Fnet = 0

## The Attempt at a Solution

I know that the answer is zero because the equation, expanded, is: ½mv

_{f}

^{2}-½mv

_{i}

^{2}. Since final and initial velocity is the same, the net work will be zero... but I'm having difficulty trying to conceptualize the idea. So is kinetic work only present if the object is accelerating, either speeding up or slowing down? How does

__net__work differ from work?
