Coefficient of Restitution.

Plastic Collision = 0.

Elastic Collision = Between 0-1.

Perfectly Elastic Collision = 1.

There is difference in word perfectly elastic and elastic, e=1 perfectly elastic collision not for elastic collision.

Friends, how to find out the co-efficient of restitution. By using velocity and height of the object after impact.

Jitendra said:   1 decade ago
For perfectly elastic cor : 1.

For perfectly inelastic cor : 0.

For partially elastic cor: 0 <e<1.

Hello @Venu, elastic means "two bodies are tends to elastic collision its coefficient of restitution e=1.

What is coefficient of restitution? Can you give examples of elastic collision b/w elastic bodies?

Afridi Ansari said:   4 years ago
COR of Elastic bodies is 0-1 and for perfectly elastic is 1. So, the given answer is correct.

COR for perfectly elastic bodies will 1 only, hence answer of this question will be A not B.

COR is the ratio of relative velocity after impact to the relative velocity before impact.

Guys how can an elastic collision occur unless and until the bodies are elastic.?
