In introductory mechanics, the momentum of a particle is its mass times its velocity. In electrodynamics, the momentum of a field is proportional to the cross-product of the electric field with the magnetic field. In special relativity, momentum is generalized to four-momentum.

Validity of Conservation of Momentum
to time gives momentum to be a constant value. … If instead, there IS net force on a system, then rate of change of momentum is constant (non-zero) and momentum is not constant but a linear function of time instead. …

Why water coming out from narrow pipe hurt more than same amount of water coming out from br...
Once we conclude that velocity from narrow is greater than velocity from broader, a simple use of Bernoulli's equation and the relation that p=mv and that force is the time rate of change of momentum, …
