Does a collision that happens in water have a stronger impact than a collision on land?
Conservation of momentum is a fundamental law of physics that states that the total momentum of a closed system remains constant over time, regardless of any internal or external forces acting on the system. This means that the total momentum before an event or interaction is equal to the total momentum after the event.
Conservation of momentum is important because it allows us to understand and predict the motion of objects in a system. It is applicable in a wide range of situations, from simple collisions to the movements of celestial bodies in space.
The total momentum of a system can be calculated by multiplying the mass of an object by its velocity. For a closed system, the total momentum before an event is equal to the total momentum after the event. This means that the sum of all momentum vectors in the system before the event is equal to the sum of all momentum vectors after the event.
No, according to the law of conservation of momentum, the total momentum of a closed system must remain constant. This means that momentum cannot be lost or gained within the system, but it can be transferred between objects within the system.
Some real-life examples of conservation of momentum include a game of pool, where the momentum of the cue ball is transferred to the other balls upon impact, and a rocket launching into space, where the momentum of the gas being expelled is equal and opposite to the momentum of the rocket propelling forward.
