➮The part of the universe chosen for analysis is called a system.

➮Everything outside the system is called an environment.

➮For example, a car moving with constant velocity can be considered a system. All the forces within the car are internal forces and all forces acting on the car from the environment are external forces like friction.

One of the most powerful laws in physics is the law of momentum conservation. For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
