In a closed system, the statement that is always true is:
**Momentum is conserved.**
This is in accordance with the principle of conservation of momentum, which states that the total momentum of a closed system remains constant if no external forces are acting on it.

The phrase that best defines momentum is:
**the motion of an object.**
Momentum is a vector quantity that describes the motion of an object and is defined as the product of an object's mass and its velocity. While not a precise definition, it captures the essence of momentum as related to motion.
