The measure of the force exerted by air molecules on a surface per unit area is air pressure.
it is AIR PRESSURE
usa
Air pressure is the force (weight of Earth's atmosphere) exerted on you by the weight of tiny particles of air, the air molecules above and around you. This is also referred to as "barometric pressure" (measured with a barometer) and will change with altitude or elevation. The standard pressure is 1 ATM (atmosphere), equal to 101325 pascals or 1013.25 mbar.
The upthrust exerted by surrounding air on the balloon.
The force exerted by air in all directions is called air pressure. It is caused by the collisions of air molecules with surfaces. Air pressure is exerted equally in all directions and decreases as altitude increases.

Air Pressure
drag force (frictional force exerted by air) or air reststance

The air pressure is exerted in the direction of the air flow. But this is subjected to the Boyle's law. So Boyle's law is correct. You have add the force exerted by the speed of the air to it.
When water molecules are moving closer together in the air it is called
