Jan 15, 2019 at 22:46 comment added FGSUZ You can push a wall for hours. Your boss tells you to move the wall. What work have you done? None, so you'll be fired. That's a joke, but check that making a force can be useless if you don't move the object. You're using your force to fight another force... but that's not changing the energy.

May 9, 2018 at 19:46 comment added safesphere Perhaps you should look at power (work per unit of time) to better understand work. For example, if you engine runs at a constant power to accelerate your car or spaceship (ignoring friction), then the work would be linearly increasing in time for as long as the engine is running. It also is always better to say "with no limit" instead of "infinitely", because the infinite is not a scientific concept (despite a widespread confusion).
