The principle of conservation of linear momentum states that in the absence of external forces, the total momentum of a system remains unchanged. This means that if an object has a certain momentum before an interaction occurs, the total momentum of the objects after the interaction will be the same as the total momentum before the interaction. This principle holds true for both elastic and inelastic collisions.
The principle of conservation of linear momentum states that the total linear momentum of an isolated system remains constant if no net external force is acting on it. In simpler terms, it means that in the absence of external forces, the total amount of momentum before an event will be the same as the total amount of momentum after the event.
