Final answer:
Conservation of momentum explains how the total momentum in a system remains constant unless external forces act upon it, with examples such as collisions and rocket propulsion showcasing this principle.
Explanation:
Conservation of momentum states that the total momentum of an isolated system remains constant unless acted upon by an external force. This principle is a fundamental concept in physics that explains various phenomena, such as the motion of objects before and after collisions.
An example demonstrating conservation of momentum is a collision with a parked car. In this scenario, the total momentum of the cars involved remains the same before and after the collision, showcasing the conservation of momentum principle.
Another illustrative example is a rocket, where mass is not constant due to fuel being ejected to provide thrust, yet the overall momentum of the system is conserved.
