The sum of momentum of the two objects before collision is equal to the sum of momentum after the collision provided there is no external balanced force acting on them this is known as law of conservation of momentum
In a closed system: total momentum before an event = total momentum after the event. A 'closed system' is something that is not affected by external forces. This is called the principle of conservation of momentum .
