WONDER CHAMBER / MATERIAL STUDY 01
Where impact goes.
Same ball. Same height. Three ways to give the energy back.
The absorber returns almost nothing. It keeps the impact as heat.
100 g balls · Kelvin–Voigt spring + damper · chosen effective specimens.Orange is amplified thermal false color (full scale +0.03 K), not visible incandescence. Heat stays in the discs until you start a fresh trial. Contact is instantaneous here; the model permits a tensile tail. Drag to inspect.
