Law of Conservation of Momentum Formulas

pi=pf

pi+pf=pi+pf

(miVi)+(mfVf)=(miVi)+(mfVf)

Symbol English Metric
pi = Initial System's Momentum lbmft/sec kgm/s
pf = Final System's Momentum lbmft/sec kgm/s
mi = Initial Mass lbm kg
Vi = Initial Volume ft3 m3
mf = Final Mass lbm kg
Vf = Final Volume ft3 m3

Law of conservation of momentum is a fundamental principle in physics that states that the total momentum of an isolated system remains constant if no external forces act upon it.  In other words, the total momentum before an event or interaction is equal to the total momentum after the event or interaction.  Momentum is a vector quantity that depends on an object's mass and velocity.

According to the law of conservation of momentum, if no external forces (such as friction or collisions with other objects) are acting on a system, the total momentum of that system will be conserved.  This law finds broad applications in various areas of physics, such as mechanics, collisions, fluid dynamics, and particle physics.  It helps in analyzing and predicting the motion and interactions of objects and particles in different physical scenarios.
