Pressure is defined as force per area or P = F/A. So, if I push my hand against a wall with the force of 10 newtons, I am dispersing that 10 newtons over the area of my hand. If my hand is say 7in * 4 inches, that would give a total area of 28in^2. The pressure I am exerting on the wall would be P = F/A = 10 Newtons/(28in^2) = .36 N/in^2.
If instead of pushing the wall with my hand, I push a nail against the wall, I am now applying the same 10 newtons of force, but my area is a fraction of the size. Since A goes down, pressure will go up. So now, my area may be A = 0.1in^2. P = F/A= 10Newtons/(.1in^2) = 100 N/in^2.

How does pressure vary with respect to area and force?
Pressure is directly proportional to force and inversely proportional to area. This means that an increase in force applied to a given area will result in an increase in pressure, while spreading the force over a larger area will decrease the pressure. Mathematically, pressure = force / area.
How does pressure vary with force?
Pressure is directly proportional to force, according to the formula pressure = force/area. This means that as force increases, pressure also increases as long as the area remains constant. So, a greater force applied over the same area results in higher pressure.
What is the quantity of pressure?
Pressure is a measure of force applied over a specific area. It is usually measured in units such as pounds per square inch (psi) or pascals (Pa). The quantity of pressure can vary depending on the force applied and the area over which it is distributed.
What is the difference between pressure and stress?
Pressure is the force applied over a specific area, while stress is the internal force created within a material in response to an applied load. Pressure is usually external and uniform, while stress is internal and can vary depending on the material's properties.
Will anyone answer you what is the force that air exerts on a given area?
The force that air exerts on a given area is called air pressure. Air pressure is the result of the weight of the air above the given area pressing down on it. This pressure can vary depending on altitude, weather conditions, and temperature.
