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 difference between tension and pressure in physics?
There is a huge difference between tension and pressure in physics. Tension refers to a pulling force and pressure refers to a pushing force.
That is the difference between force and pressure?
Pressure deals with the impact on a particular surface while force is the total impact on a particular surface
What is the upward force due to a pressure difference between the top and bottom of a wing?
The upward force is called lift.
What is the difference between a buoyant force on an object and the pressure on an object surrounded by a fluid?

What are relationships between pressure and force and between pressure and area?
pressure is force divided by area
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.
Force produced by a pressure difference?
The pressure gradient force is not actually a force but the acceleration of air due to pressure difference (a force per unit mass).
What is relationship between pressure and force?
Pressure = Force/Area
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 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.
What is the mathematical relationship between force pressure and are?
Pressure = Force/Area.
