Question

law of conservation of Momentum

​

Answer 1

Answer:

$m1 \times v1 = - m2 \times v2$

Explanation:

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. That is, the momentum lost by object 1 is equal to the momentum gained by object 2.
