In which, elastic or inelastic collision, the momentum is conserved ? What about K.E.?

Define elastic and inelastic collision.

An elastic collision conserves

In an elastic collision which quantities are conserved ?

In non-elastic collision, both momentum and kinetic energy are conserved.

In a gas -filled container, a molecule of speed 200 m//s collides at an angle of 30^@ with the horizontal face of this container, and rebounds with the same speed. Is the collision elastic or inelastic? In this momentum conserved in this collision?

Which of the following statements is false for collisions- (1)Momentum is conserved in elastic collisions but not in inelastic collisions. (2)Total-kinetic energy is conserved in elastic collisions but momentum is not conserved. (3)Total kinetic energy and momentum both are conserved in all types of collisions (4)Total kinetic energy is not conserved in inelastic collisions but momentum is conserved

Assertion: There is not loss in energy in elastic collision. Reason: Linear momentum is conserved in elastic collision.
