Conservation of momentum is a fundamental principle in physics that states that the total momentum of a closed system remains constant. This means that in a system where no external forces are acting, the total momentum before an event must equal the total momentum after the event.
Conservation of momentum is important because it helps us understand and predict the motion of objects in a closed system. It is a fundamental principle of nature and is used in many areas of physics, including mechanics, astrophysics, and fluid dynamics.
Conservation of momentum is applied in real life situations such as collisions between objects, rocket propulsion, and the movement of planets in our solar system. It is also used in sports, such as billiards and ice skating, to predict the trajectory of objects.
The conservation of momentum is affected by the mass and velocity of objects in a closed system. In elastic collisions, the momentum is conserved even after the collision, while in inelastic collisions, some momentum is lost due to the deformation of objects upon impact.
No, the conservation of momentum is a fundamental law of physics and cannot be violated in a closed system. However, in some cases, it may seem like momentum is not conserved due to external forces that are not accounted for in the system, such as friction or air resistance.
