Pressure depends upon the factors that follows:-. (1)It depends on force applied. (2)Area over in which force acts. The same force can produce different pressure depending upon area in which it acts. When the force acts over a large area,the pressure produced is less.
Pressure is the ratio of force to the area over which that force is distributed. In other words, pressure is force per unit area applied in a direction perpendicular to the surface of an object. Pressure may be measured in any unit of force divided by any unit of area. The SI unit of pressure is the pascal (Pa). One pascal is defined as one newton per square meter. A pressure of 1 Pa is small, therefore everyday pressures are often stated in kilopascals (1 kPa = 1000 Pa). The pressure in car tires can be in the range of 180 to 250 kPa.
