State the law of conservation of liner momentum and describe its consequences

Answer 1

The law of conservation of linear momentum states that the total linear momentum of a system remains constant unless an external force acts on the system. This means that the momentum of a system can be changed, but only if an external force is applied. The consequences of this law are that the momentum of a system can be transferred from one object to another, but the total momentum of the system remains the same. For example, when two objects collide, the momentum of each object is transferred to the other, resulting in a change in the momentum of each object, but the total momentum of the system remains the same.
