Conservation of momentum is always applicable in a:
Correct answer: C. Isolated system
- A. Open system
- B. Closed system
- C. Isolated system
- D. Any system
Explanation
An isolated system is a collection of particles that can interact with each other but whose interactions with the environment outside the collection have a negligible effect on their motions. So; For an isolated system there is no net force acting. In absence of external force the final momentum of a system must be equal to initial momentum according to newton's second law of motion in terms of momentum. This way the total momentum of the system cannot change.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
