    Concept:

    Momentum: The product of mass and velocity is called momentum or linear momentum.

    It is denoted by P and unit is kg⋅ m/s

    Momentum (P) = Mass (m) × velocity (V)

    Conservation of linear momentum: When there is no net external force on a system, then the total linear momentum of the system remains constant. This is called the conservation of linear momentum.

    Explanation:

    In the case of a rocket, we will take the rocket and its fuel as a system. There is no net force on this system, so the total momentum will be conserved.

    Thus the rockets work on the law of conservation of linear momentum is correct.

    The increased forward momentum of the rocket is equal but opposite in sign to the momentum of the ejected exhaust gases.
