🏀 Bounce Lab: Restitution from Bounce Heights, Energy Loss & Spin

Drop or launch five different balls onto five floors and measure the coefficient of restitution from successive apex heights, with Coulomb friction and spin at impact, air drag and Magnus lift, and a check of the simulated stopping time against the geometric-series formula.
