The 44lbs first needs to be lifted into place and that requires work against gravity. It is like attaching a thread to a weight, then lifting the weight by the thread and lastly cutting the thread with scissors. Nothing free here.
On the other hand, what if we are talking about a system in rotation (like my spinning skater) where a centrifugal force is what matters instead of gravity?
