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.
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.
