    Potential Energy Transfer from a large mass to accelerate a smaller mass upward

    Your question rejuvenates me:)

    Potential Energy Transfer from a large mass to accelerate a smaller mass upward

    Thanks everyone. I actually had some errors in the spreadsheet that underestimated the potential energy transfer. Fixed it for now. Merry Christmas and Happy New Year.

    Potential Energy Transfer from a large mass to accelerate a smaller mass upward

    A pulley with an inclined plane? Thanks, but that doesn't work. It's one of many possible examples where the large mass conserves much of its energy at the end of its path (kinetic), without transferring it to the mass that is going up.

    Potential Energy Transfer from a large mass to accelerate a smaller mass upward

    With the potential energy of a large mass (for example 50 kg at 10 meters high) I want to accelerate a smaller mass (5-25 kg) upwards. I see that simple mechanisms like pulleys, levers, and simple gears leave a lot of kinetic energy in the large mass when it reaches the ground. Is there some...
