IN general change is defined as the difference of initial from the final.
So change = Final - Initial.
Hence change in momentum = Final momentum - initial momentum
Impulse momentum theory: when force is applied to a rigid body it changes the momentum of the body. it is calculated with respect to time and also the velocity is calculated.

its velocity.
Conservation of momentum means that momentum is a constant and the change of momentum or force is zero.
Momentum is mass times velocity. Without knowing the speed of the rocket, momentum cannot be calculated.
Use this formula:Final momentum = (initial momentum) + (change in momentum)
change in momentum
An impulse is a change in momentum.
Momentum of a particle is the measure of quantity of motion in its and is given by product of its mass and velocity. That is p = mv ,if m and v are known ,momentum can be calculated.
It is called the momentum-impulse theorem and states that an impulse will change the momentum of an object. For example, if you drop an object when it hits the ground an impulse occurs. The momentum of the object also changes. Jnet = deltap, where deltap is the change in momentum.
