Its not law of conversation of energy. It is a part off statement from newton's law.

Newtons 2 law and law of conservation of energy combined. So it is false statement.

True, when no change in momentum takes place either we say statically condition.

The force applied should be an external 'unbalanced' force in that direction.

Free molecule have different masses & momentum so without acting force.

Law of conservation of energy system neither be created nor be destroyed.

Momentum is a vector quantity so change in direction change the momentum.

Momentum changes with gravity, and gravity changes from place to place.
