Hi
Here is the equation for the momentum
p = m x v
here m indicates mass and v indicates velocity.
Using words it can also be written as:
Momentum = mass x velocity
Momentum of a body is basically the product of its mass and velocity.The standard unit of momentum is the kg x m/s, because the unit of mass is kilograms or kg and unit of veocity is metre per second or m/s, Therefore the product of both is the unit of momentum.
Hope it help!
