elastic collision.....

None

in an elastic collision why does not the K.E remains constant ???

In an elastic collision, K.E. always remains same since the co-efficient of restitution i.e. e=1. It indicates that there is no loss of energy & energy remains constant.Recheck ur ques.

rate if convinced or nudge

in an elastic cllision;

there is no conversion of KE into PE in the form of any permanent deformation.

Moreover, there is no dessipiative energy loss in the form of heat or light.

thus conserving tot energy, KE remains constant.

Rate if convinced.......

Are you sure that KE DOES NOT remain constant.???????

Because for perfectly elastic collsion the Kinetic Energy of the SYSTEM remains constant. However the KE of individual particles may change if the bodies have different momenta before collision. However for two bodies colliding elastically, there is mutual exchange of KE after collision.....

in elastic collision ke remains cont. or is transferred 2 some other particle as purav said for eg.

collision betwn subatomic particles

collision btwn gaseous molecules r elastic collisions
