Question

the law of conservation of momentum starts that
1. mass after collision is equal to mass before collision.
2. velocity after collision is equal to velocity before
3. momentum after collision is equal to momentum before collision
4. total momentum after collision is equal to total momentum before collision.
which one is correct​

Answer 1

Answer:

Option 4 is right

Explanation:

Hope it helps you

Answer 2

The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
