COR=1 for elastic collision not elastic bodies.

What is mean by elastic collision?

Sagar said:   1 decade ago
When 2 bodies hit without losing momentum its elastic collision.

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

Harish said:   1 decade ago
The coefficient of restitution (COR) of two colliding objects is a fractional value representing the ratio of speeds after and before an impact, taken along the line of the impact.

What is coefficient of restitution?

Can anyone explain clearly regarding the difference of elastic bodies and elastic collision. I think then it will be clear to differentiate between the coefficients.

The difference between elastic & perfectly elastic body is if the body is perfectly elastic then the value of e is 1.

Nikhil said:   1 decade ago
Coefficient of restitution is a thing which will be experienced only when the bodies collide with each other and for a perfect elastic collision we need elastic bodies. Therefore this answer is wrong and e=1 for elastic bodies.
