it is AIR PRESSURE
That measure of force per unit area is called the pressure exerted on the surface.
Air Pressure
You're looking for "air pressure", but you haven't described it correctly.The pressure is not the force pushing on the surface.It's the (force pushing on the surface) divided by the (area of the surface).
a spring balance is used to measure a pushing or pulling force.
air
Surface tension. Translated that means that the attraction between the water molecules (to each other) is greater than the force (gravity) pushing the needle down.

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.
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")
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.

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

Air Pressure means the measure of the force with which air molecules pushed on a surface.
