###### Answer: p initial = p final
Which formula can be used to express the law of conservation of momentum where p = momentum?

Conservation equations. The Boltzmann equation can be used to derive the fluid dynamic conservation laws for mass charge momentum and energy.: p 163 For a fluid consisting of only one kind of particle the number density n is given by = ∫. The average value of any function A is

Linear momentum translational momentum or simply momentum is the product of a body’s mass and its velocity: p = m v {\displaystyle \mathbf {p} =m\mathbf {v} } where p is the momentum m is the mass and v is the velocity.

The equation expressing conservation of momentum is: + = (+). If one body is motionless to begin with (e.g. =) the equation for conservation of momentum is

Conservation of four-momentum gives p C μ = p A μ + p B μ while the mass M of the heavier particle is given by −P C ⋅ P C = M 2 c 2.

The law of conservation of momentum states that the total momentum of a closed system of objects (which has no interactions with external agents) is constant. …
