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.

∙ 8y agoPressure is force / area. If the force remains the same, then, if the area changes, so will the pressure.

How does pressure vary with force?
pressure is force divided by area
Why does pressure of fluid vary with depth?
For a very basic explanation, pressure is the amount of force in any given area. Hydrostatic pressure, or fluid pressure, is the amount of force exuded at equilibrium due to gravity. So at any given point in a fluid, the pressure is equal to the weight of the fluid above it as well as the depth below it.
How does barometric pressure vary with altitude?
pressure is a physical unit that measures what we may call the density of force i.e. trhe amount of force exerted on a certain area , the atmosphiric pressure is the force exerted by the air mass on a certain area , clearly more air means more mass , thus , when we go down the air above us increases , and when we go down the amount of air decreases.
Is it true that when a constant force is applied to a body it moves a uniform acceleration?
Yes, that is true - assuming you are referring to the net force, i.e., the sum of all forces on an object. Please note that in practice, opposing forces such as air resistance may vary depending on speed.
What is the pressure of a tornado?
No one really know pressure can vary for the type or category of a tornado.

What is the surface pressure on the sun?
The surface pressure of the earth is nominally 1013.25 hectoPascals (hP), which is also referred to as 1 The surface pressure of the earth will vary slightly according to weather conditions.
How does the walls reaction force vary as you vary the force you push it with?
This is to do with Newtons 3rd law of motion. To evey action there is an equal and opposite reaction. The wall's reaction force is a way of expressing the total force that is being applied on the wall. In order to calculate the reaction force you need to be able to apply calculations to correctly estimate the total force. FT= FR+ FA if FT = FA then the FR= FA Where R is reaction, A is applied, and T is toal force.
Is friction independent of the area of contact?
Generally no. The friction force is typically assumed independent of surface area, and proportional to the force between the two objects. By changing the contact area, you are changing how that force is concentrated. i.e. a small surface area means that your force is distributed across a small region, creating a high pressure (force/area) at the contact. By increasing the surface area, you distrubte that force and lower the pressure. This is, however, an idealization and can break down in some instances.

How do you lighten the skin tone of the genital area?
A high level of bleach should be applied directly to ball sack, or vaginal area. Results vary.
What is the pressure in feet per second created by a car running ai 50 miles per hour Cubic feet second created by the car with the air?
First of all, feet per second is a unit of speed, not of pressure. Pressure is measured in Newton per square meter, or some other unit of force, divided by a unit of area.The pressure situation is quite complicated; it would vary, depending on the exact shape of the car.First of all, feet per second is a unit of speed, not of pressure.

How does atmosphere pressure vary with altitude?
How does liquid pressure vary with depth
Does pressure vary with dept due to the force of gravity?
Yes, pressure increases with depth as a result of the weight of water above a given depth. Weight is caused/determined by gravity.
How does the size of an electrolyte capacitor vary with its capacitance value?
A: Capacitance vary directly with the area applied the bigger the area the bigger the capacitor. There is another element that will increase the size that is the rating of the capacitor voltage since more material will have to be used to insulate the plates
How do sexual sensations vary?
I do not know the subject extensively, but I do know: sexual sensations during intercourse depend on speed of movement, depth of penetration, and pressure applied. What else would matter?
