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.
