Linear momentum is a fundamental concept in physics, representing the momentum of translation for an object. It is defined as the product of an object's mass and its velocity. This means momentum has both magnitude and direction, classifying it as a vector quantity.12

A key principle related to linear momentum is its conservation. The law of conservation of linear momentum states that in an isolated system, the total momentum remains constant. This means that if no external forces act on a collection of objects, their total momentum will not change, regardless of interactions within the system. For example, in a collision between two particles, the total momentum before the collision is equal to the total momentum after the collision; any momentum lost by one particle is gained by the other. This principle is crucial in understanding various physical phenomena, from rocket launches to particle collisions.34
