1R40.10

[:MEEquipmentList:Bouncing Ball]

Drop balls of different material on to a tool steel plate. Loss of mechanical energy in the coefficient of restitution. Drop balls on a glass plate. Balls of various materials are bounced off plates of various materials.

1R40.10

Coefficient of Restitution

Drop glass, steel, rubber, brass, and lead balls onto a steel plate.

1R40.11

Coefficient of Restitution

Drop a small ball bearing on a concave lens.

1R40.12

Coefficient of Restitution

Rubber balls of differing elasticity and silly putty are dropped in a tube onto a steel surface.

1R40.13

Coeffficient of restitution in Baseballs

Analysis leading to a prediction of up to 15 foot difference in long fly balls due to variation in coefficient of restitution.

1R40.30

[:HappySad:Happy and Sad Balls]

One bounce and the other doesn't.
