Change in momentum of a body is defined as the change in the product of mass and velocity of the body.
It is given as:
Change in momemtum, Δp=Δ(mv)
The change in the product can be due to either the change in mass or due to change in velocity or both.
 
The rate in change of momentum of a body is equal to the product of mass of an object and acceleartion produced in it due to the force acting on the body provided that the mass of the object remains constant.
It is given as:
Rate of change of momentum = mass × acceleration 
Or, begin mathsize 12px style Δp over Δt equals space ma end style
