Which is always true in a closed system?(1 point) Responses Momentum is conserved. Momentum is conserved. Acceleration is not constant. Acceleration is not constant. Velocity is constant. Velocity is constant. Mass is not conserved.

Answer 1

In a closed system, momentum is conserved. This means that the total momentum of the system remains constant if no external forces are acting on it. Therefore, the correct statement from your options is:

Momentum is conserved.
