If you attatch a falling mass to a load (electric motor, lightbulb, ect.), the mass accelerates more slowly than 9.8 m/s. I know the power of the falling mass is mgh. My question is how to get the mass to fall as slowly as possible, assuming a fixed mass (changing the power that the load is taking). It seems to me as if the larger the load is, the more power it requires, the smaller the acceleration of the mass is. But if the mass never accelerated (taking it to an extreme), it wouldnt power the load would it? Where is the balance, the perfect load to make the mass move as slowly as possible?
