What is the relation between the thrust and pressure?
Thrust is the force exerted in a specific direction, while pressure is the force distributed over a certain area. In general, to increase thrust, the pressure of the fluid or gas being expelled must increase. This relationship is commonly seen in propulsion systems like rockets and jet engines.
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 direction does static pressure exert?
Static pressure exerts a force perpendicular to the surface it acts upon. This pressure is uniform in all directions and does not have a specific direction of its own.
How does pressure relate to force and what is the connection between the two?
Pressure is the amount of force applied over a given area. The relationship between pressure and force is that pressure increases when the force applied is greater or when the area over which the force is applied decreases. In other words, pressure and force are directly related - as force increases, pressure also increases.
How do you classify the force system?
Force systems can be classified as concurrent, parallel, or non-concurrent. Concurrent force systems have all forces intersecting at a common point. Parallel force systems have forces acting in the same direction. Non-concurrent force systems have forces that do not meet at a common point.
