500 1R40.10 bouncing balls 1R40.10 Drop balls of different material on a tool steel plate. Balls of various materials are bounced off plates of various materials. 1R40.10 bouncing ball 9-1.5 Loss of mechanical energy in the coefficient of restitution.
Drop balls on a glass plate.
1R40.10 coefficient of restitution Disc 05-04 Drop glass, steel, rubber, brass, and lead balls onto a steel plate. An eight inch or larger reflecting telescope mirror blank provides a concave surface for bouncing balls. 1R40.11 coefficient of restitution 9-5.5 Drop a small ball bearing on a concave lens. 1R40.12 coefficient of restitution M-19j.1 Rubber balls of differing elasticity and silly putty are dropped in a tube onto a steel surface. 200 Drop bounce and no-bounce balls.
