Momentum is a vector quantity that is the product of the mass and the velocity of an object or particle. The standard unit of momentum magnitude is the kilogram-meter per second (kg · m/s or kg · m · s -1 ).
The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the totalmomentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.

Momentum is a vector because velocity is a vector and mass a scalar. Momentum is defined as the product of mass and velocity. For a particle of mass m and velocity v, the momentum p is mv.
Where momentum is denoted as “p”, mass is denoted with “m” and velocity is denoted with “v”.
Momentum = mass × velocity
p = m × v
S.I Unit of momentum = kgms-1
The law of conservation of momentum states that:
"when some bodies constituting an isolated system act upon
one another, the total momentum of the system remains constant."
