Yes.

a WARM front occurs when a fast moving warm air mass overtakes a slower moving cold air mass.
A cold front is generally in the vicinity when a fast moving air mass overtakes a slower moving warm air mass. Violent or unstable weather is generally associated with this type of weather pattern.
Cold, dry air
How fast the air particles are moving
it happens when it is not exposed to moving air currents
Moving air is air that is constantly circulating in an area. Non-moving air is air that is not moving around.
Instead of saying "moving air," you could say air displation, or wind, if the air is in the act of moving.
Moving air probably has less molecules than still air because the particles are spread apart in moving air, and there is less of them, while in nonmoving air, it is packed.
An upward moving current of air is called an updraft.

a WARM front occurs when a fast moving warm air mass overtakes a slower moving cold air mass.
When warm air moving above mixes in with cool air moving below.
Moving air carries it.
the cool air will rise
a cold air mass
the cool air will rise
Fluid friction acting on an object moving through the air is called air.
