1. The problem statement, all variables and given/known data To me it makes more sence to use force*time instead of force*distance. Because when you are aplying force to an object that isn't moving you're still wasting energy. Or when you push a weight over the same distance with little force or big force, the amount of energy wasted should be the same, but it isn't because the power is different... 3. The attempt at a solution Maybe I don't understand the definition of work, but why is it measured in joules then?
