Which of the following most accurately describes conservation of momentum?
Momentum is always conserved, even when external forces are present.
Momentum can only be conserved in systems where objects are stationary.
The total momentum of a system remains constant if no external forces act on it.
Momentum conservation means all objects in a system move at the same speed.
