WebIf the total momentum of a system is changing: A) particles of the system must be exerting forces on each other B) the system must be under the influence of gravity C) … Web1 jun. 2024 · It states that the amount of momentum in a system remains the same no matter which object is moved. Momentum is also the quantity that cannot be created, but can be changed by external forces. As a result, dealing with momentum is more complicated than dealing with energy or mass.
