i agree with gain................
but it depends on what the context is..............
in elastic collision the COR is 1 ....
otherwise the objects would just stick to each other which is not the case...........
but then that's a sort of approx becoz actually
ALL COLLISIONS BTW REAL OBJECTS ARE SEMI-ELASTIC.......
WHERE
e- = coeff of restitution = relative velocity of recession / approach......
v2 - v1 / u1 - u2.............
thus ...........both the statements may not necessarily be true..
ke is definitely conserved.........but COR is not always 1......
but in the broader picture yes..........sort of approx u know
