Momentum and impulse both has same unit Kg ms-1.
Momentum is the quantity of motion and is compounded by the quantity of the matter moved and the velocity with which it moves. Momentum is present when you walk, run, etc. If a bicycle and a car travel down the street at an equal velocity, the car will have the most momentum.
Momentum = Mass (m) x Velocity(v)
mpulse is often stated to be the product of the average net force that acts on an object for a certain duration. The equation for impulse is given as;
J = F⋅Δt
