In elastic collision,

STATEMENT-l : In an elastic collision between two bodies, the relative speed of the bodies after collision is equal to the relative speed before the collision. STATEMENT-2 : In an elastic collision, the linear momentum of the system is conserved.

Statement I: In an elastic collision between two bodies, the relative speed of the bodies after collision is equal to the relative speed before the collision. Statement II: In an elastic collision, the linear momentum of the system is conserved.

Assertion: In inelastic collision, linear momentum of system does not remain constant during collision. But before collision and after collision, it is constant. Reason: In elastic collision, momentum remains constant during collision also.
