If I have a 2 box with the same weight and I am to bring it up two inclines with different heights but different level of steepness. Will the work done to bring the object up be the same? Because if the incline have the same surface then it has the same amount of friction. Logical it would seem that the less steep incline will have the greater work done to bring in up as the amounts if work done against friction will be greater. But then again, it would also seem that to push something up from ground to the higher level from a steep incline then work done is required. But I'm not sure about this. Thanks for the help!
