The Law of Conservation of Momentum states:

• The total momentum before a collision is equal to the total momentum after a collision.

• The total momentum before a collision is greater than the total momentum after a collision.

• The total momentum before a collision is less than the total momentum after a collision.

• The total momentum before a collision is not related to the total momentum after a collision.

Momentum is always conserved in collisions, what do we call a collision in which kinetic energy is not conserved?

• inelastic collision

• elastic collision

• conservation of energy

• stable collision
