Our atmospheric pressure is the pressure at any given point in the Earth's atmosphere. In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point.
Formula: Pressure p = force F / area A
Pressure p in pascals (Pa)
Force F in newtons / square meters (m²)
Area A in sqare meters (m)
The standard atmosphere, symbol: atm, is a unit of pressure and is defined as being precisely equal to 101325 pascals.

What is the relationship between area and pressure of a constant force?
The area over which a force acts, is proportional to the pressure. When the area is large then, the pressure acted on it is also large, so the force is greater.
How does pressure differential move fluid from one storage tank to another?
This is comparable to two people pushing an object in opposite directions; if one pushes with more force than the other, the object will move in that direction (the direction in which more force is applied).Note that pressure is force per unit area.
What is presure?
Pressure is an effect which occurs when a force is applied on a surface.Mathematically pressure is: p = F / Awhere: * p is the pressure,F is the normal force,A is the area.
How is force multiplied by a hydraulic system?
input pressure X area = output pressure X area
What is the formula used to calculate pressure?
Force over Area= Pressure
When the force applied on an object is doubled how does the pressure applied on an object change?
It will be double, if the area is unchanged. pressure=Force/area
When Force divided by the area over which the force is exerts pressure?
yes, force divided by area is pressure; its units are pounds per square inch, or newtons per square meter, for example. I you pull on an object with force over an area it is called stress
When the force applied an object is doubled how does the pressure exerted on the object changes?
When the force is doubled the pressure is doubled as well. Read Newton's law.
One force affecting an object is air pressure which is?
One force that affects and object is air pressure which is the force pushing on an area or surface.
The force exerted on a surface divided by the area over which the force is exerted?
Pressure is the force exerted on an object divided by the area where the pressure was applied.
What is the formula relating pressure and force to area?
pressure = force/area force = pressure x area area = force/pressure
What is the equation for pressure when the force is perpendicular to the surface area?
Pressure of solid on a solidWhen you apply a force to a solid object, the pressure is defined as the force applied divided by the area of application. The equation for pressure is: P = F/AwhereP is the pressureF is the applied forceA is the surface area where the force is appliedF/A is F divided by AFor example, if you push on an object with your hand with a force of 20 pounds, and the area of your hand is 10 square inches, then the pressure you are exerting is 20 / 10 = 2 pounds per square inch.
What is the difference between force and pressure?
A force is a push or a pull which changes how fast an object moves. Pressure is the force on an object divided by the area over which the force is spread. A force will change the velocity of an object. This means it will start it moving if it is still, stop it moving, speed it up, slow it down or change its direction! Pressure takes into account the area over which the force is acting. A force spread over a big area will give a low pressure. The same force spread over a small area will give a high pressure. For an excellent account of force and pressure see the links below. You might think of force as a 'vector' and pressure as a 'scalar'. A vector must include direction as a parameter as well as magnitude; and a scalar has magnitude without dependence on direction. Force on an object when the force is not balanced by other forces will compel an object to move. An object sitting motionless at one atmosphere of pressure will not be compelled to move simply because of the presence of the pressure alone. Pressure is the force over an area applied to an object in a direction perpendicular to the surface. Force is a push or pull that can cause an object with mass to accelerate. Force has both magnitude and direction. p = F / A, where:p is the pressure,F is the normal force,A is the area.
What is the relation between force and area?
Pressure is the force over an area applied to an object in a direction perpendicular to the surface. p = F / A where:p is the pressure,F is the normal force,A is the area.
What is the amount of force exerted on a given area?
That is pressure. It is the force over an area applied to an object in a direction perpendicular to the surface.p = F / A where:p is the pressure,F is the normal force,A is the area.
What is the difference between pressure ane force?
Pressure is the force over an area applied to an object in a direction perpendicular to the surface. Force is a push or pull that can cause an object with mass to accelerate. Force has both magnitude and direction. p = F / A, where:p is the pressure,F is the normal force,A is the area.
Is it true that pressure is defined as the force one object exerts on another object?
Pressure is defined as a force per unit area directed normal to the surface.Pressure is not defined in terms of the force one object exerts on another object, but such a circumstance that certainly is an example of a pressure.Caveat: Admittedly, one could argue as to how any force could be exerted on an object if it were not in contact with another, but such is too limited an idea for a definition. One would have difficulty characterizing pressure in the depths of the ocean if one had to identify what objects were in contact. One must further note that pressure is not a vector whereas force is a vector.
