Bounce Height

First bounce: e compares the speeds: after over before
Pick the floor: e from two heights: e = √(h₁ / h)
Energy lost: KE after a bounce is e² times KE before
Bounce till it stops: Add the falls and the bounces: a geometric series
Off the roof: On smooth ground, only the up-down part bounces
Slide, fly, bounce: Chain the steps: ramp, flight, bounce

Drop a ball and watch it bounce lower each time. Find e from the bounce height.
