What this tool does
Lifting something stores energy equal to its weight times the height gained. Let it fall and that same energy reappears as motion, which is the third result: the speed the object reaches at the bottom.
Formula
E = m × g × h

Limitations
- The formula assumes ideal conditions: no friction losses, no air resistance and no efficiency losses unless you enter them.
