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 formula for vaccum force?
The formula for vacuum force can be calculated as: Vacuum force = Pressure difference x Area Where the pressure difference is the difference in pressure between the vacuum and the surrounding atmosphere, and the area is the surface area over which the force is acting.
What is the upward force due to a pressure difference between the top and bottom of a wing?
The upward force due to a pressure difference is called lift. It is generated when the air pressure below the wing is higher than the pressure above the wing, creating a pressure difference that causes the wing to be pushed upward.
What is the driving force of different unit operations?
The driving force of different unit operations can vary depending on the specific process involved. For example, in distillation, the driving force is the difference in vapor pressure between the components being separated. In filtration, the driving force is the pressure difference across the filter medium. In heat exchangers, the driving force is the temperature difference between the two fluids exchanging heat.
When the pressure of the bottom of a submerged object is less than the pressure at the top of the submerged object a buoyant force is produced?
greater than
What is the origin of upthrust in fluid?
Upthrust in fluid, also known as buoyant force, is caused by the pressure difference between the top and bottom of an object submerged in a fluid. This pressure difference creates a net force pushing the object upwards. It is a result of Archimedes' principle, which states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.
What is the difference between thrust and pressure-?

What is the formula for vaccum force?
The formula for vacuum force can be calculated as: Vacuum force = Pressure difference x Area Where the pressure difference is the difference in pressure between the vacuum and the surrounding atmosphere, and the area is the surface area over which the force is acting.

Force produced by a pressure difference?
The force produced by a pressure difference can be calculated using the formula F = A * P, where F is the force, A is the area over which the pressure is acting, and P is the pressure difference. The SI unit for pressure is Pascal (Pa) and the unit for force is Newton (N).
Why CO2 gas comes out in force when bottles of soda is opened?
The cause is the pressure difference between the gas pressure in the bottle and the atmospheric pressure.
What are relationships between pressure and force and between pressure and area?
pressure is force divided by area

Why does the buoyancy force on an object act upward?
The buoyancy force is the upward force exerted on an object immersed in a fluid due to the pressure difference between the top and bottom of the object. This pressure difference results in a net upward force that is greater than the downward force of gravity, causing the object to float.
This force describes how water exerts an upward force on submerged objects?
This is called a "bouyant" force. It is due to the difference in water pressure between the top of the object and the bottom of the object. Water pressure increases with depth.
What is a pressure gradient and how is it related to air movement?
Pressure gradient is the rate of pressure change as you change position, not just the difference between the lowest pressure and the highest pressure, but how great (or small) the physical distance between them. Since it the pressure difference that make air flow (wind) the greater the pressure gradient, the greater the wind.
