State the Law of conselvation of moment um ols the total linear mumentum of an isuled system remains contant so it is consoried. 2.a) In the context of momentum what is an isolated system? b) Why is it necessary to choase an isolated system When solung a momentum problem?

The Law of Conservation of Momentum tells us that in a closed or isolated system, the total linear momentum remains constant as long as no external forces act on it. This means that the momentum before an interaction, like a collision, will equal the momentum after, making it a super reliable principle for analyzing motion in physics! An isolated system is essentially a scenario where no external forces are influencing the objects at play. Choosing this type of system for momentum problems is crucial because it simplifies the equations: you can assume momentum isn't being added or subtracted from outside forces, making your calculations focused solely on the interactions within the system. This leads to clearer and more accurate results!
