work on constant-velocity objects
I'm learning about Work for the first time.
Work = (force) x (distance moved in the direction of the force)
I understand what work is when it comes to lifting objects.
but if you had an object moving at constant velocity with no opposing forces, and apply some force to it in the direction of motion (say 1N), what would be the "work done" given that the object will continue to move after the force is applied.
It will move an indefinite distance so what is the distance in this case?

The distance we use is that which the object traverses while the force is being applied.
