Our momentum equation can be simplified even more by substituting the words for symbols: p = mv, where p is momentum, m is mass (in kg) and v is velocity (in m/s). Assuming that we are working within a closed system, this means that the total linear momentum will never change. Conservation of momentum examples in real life. v = 20m/s. An object travels at a constant 10 m/s. Answer: We replaced the wavelength and the Plank's constant in the photon momentum equation. Momentum is always conserved in collisions if no external forces are acting on the system. It is a vector quantity, possessing a magnitude and a direction. Examples For Relation of Kinetic Energy with Linear Momentum If m is an object's mass and v is its velocity (also a vector quantity), then the object's momentum is: $${\displaystyle \mathbf {p} =m\mathbf {v} .
