okay so input force is the amount of force that is put in right?
so you can find that by using the formula force = mass x acceleration...
but then what is input work?

work is the result of force... but then wouldn't that be output work? i don't understand the concept of input work... what is it? how do you find it?

Umm, I'm unfamiliar with your terminology but I think what you're getting at is this:

Input work would be the work done on a body or system, that is, forces that are applied to the body or system. This is in contrast to output work which is a force that is applied by the body or system to something else.
 
There are two ways you can apply force to an object:
1) Force times time dt is called an impulse and adds to the momentum of the object.

2) Force times distance dx is called work and adds energy to the object.
