How Do We Calculate Elasticity in Collisions?

[Aidman]

Hi,

I am interested in knowing how to calculate the elasticity between two objects when colliding. Let’s say I have object A and B with different “elasticises” constants. Do I then simply combine their values by adding them together and divide by two?

EDIT: Assuming that the objects’ elasticises depend on one another. Which I would also like to know if its correct. Thanks in advance :)

There are different kinds of elasticity. Typically, elasticity refers to colisions. The elasticity of a colision is:
\frac{KE_{final}}{KE_{initial}}
