Assumptions and safety

For near-Earth gravity in an approximately uniform field, U_g=mgh relative to a selected floor reference; g=9.8 m/s². The modeled body begins at rest at H and descends only to h between zero and H, before any collision. Released potential energy becomes kinetic energy and a user-prescribed fraction transferred to other forms. The fraction is an instructional assumption, not a measured drag, friction, or damping coefficient.

2. Visual energy conservation ledger

All three bars sum to initial stored potential energy. The labels and numerical readout give exact values independent of the colors.
