The measure of the force due to air pressing on a surface is called the force.
If you divide that by the area of the surface, then you have the pressure.
This force is called atmospheric pressure, the force is measured per unit area because the bigger the area the more molecules hit. It is 14.7 pounds per square inch ("psi")
Force - Meter
I'm not sure if you are talking about friction or not. Does this force produce heat? Friction, I think
The force of adhesion between water and glass molecules is greater than the force of cohesion between two water molecules.This causes the surface of the water to be curved. This curved surface is called a meniscus.
Both, the water molecules are cohesive to each other, and the outer water molecules are adhesive to the table surface.
it is AIR PRESSURE
The measure of the force with which air molecules push on a surface is air pressure. An instrument that is used to measure air pressure is a barometer.

What is normally used here is not a force, but a force per unit area; this is called pressure. The SI unit for pressure is the pascal.
The measure of the force with which air molecules push on a surface is air pressure. An instrument that is used to measure air pressure is a barometer.

Air Pressure means the measure of the force with which air molecules pushed on a surface.
Air pressure is the measure of the force with which air molecules push on a surface.
The force of attraction between molecules below the surface of a liquid is called cohesive force. This force creates an inward pull, causing the liquid molecules to stick together and form a well-defined surface.
This force is called atmospheric pressure, the force is measured per unit area because the bigger the area the more molecules hit. It is 14.7 pounds per square inch ("psi")
The measure of force with which air molecules are pushing on earths surface is called air pressure. At sea level, at what we call standard atmospheric pressure, the pressure is about 14.696 PSI, or about 29.92 inHg, or about 760 mmHg. This is 101.324
