I want to ask something with the fear of sound silly to most of you. A)Let's say we have two identical rockets and the air resistance is excluded. The first rocket travels upwards with 100mph while the second travels upwards with 50mph.It's obvious that after an hour the faster rocket will have produced double work.Does this mean that it will have used double fuels? As far as I understand it since both the rockets move with constant speed they exert the same and equal with their weight force for an hour.Isn't logical to conclude that since both the rockets use the same force for the same duration they use the same fuels too?
