Which formula can be used to express the law of conservation of momentum, where p=momentum

Explanation :

The momentum of an object is defined as the product of its mass and the velocity with which it is moving.

The law of conservation of momentum states that the total momentum of a system remains conserved when the external force acting on it is equal to zero.

Mathematically, it can be written as :

where,

and   are the initial and the final momentum.

Hence, it is the required solution.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
