Revision notes on Pressure & Forces for the CIE IGCSE Physics syllabus, written by the Physics experts at Save My Exams.
Pressure (p) is defined as the force perpendicular to a surface per unit area , and can be calculated using the following equation: p = A F Where F is the force acting perpendicular to the surface and A is its area. Using the defining equations of pressure and density, you can derive the formula p g Δh Δ =ρ used in section 5.1:
The pressure below the surface of a fluid, and in fact between any two points in the fluid can be calculated by the following equation: ressure difference = height x density x strength of the gravitational field p=hxdxg = pressure difference in pascals (Pa) = density in kilograms per cubic metre (kg/m3) = acceleration of free fall (m/s2)
20 lut 2022 · Define pressure. Explain the relationship between pressure and force. Calculate force given pressure and area. You have no doubt heard the word pressure being used in relation to blood (high or low blood pressure) and in relation to the weather (high- and low-pressure weather systems).
useful formulas and equations found in undergraduate physics courses, covering mathematics, dynamics and mechanics, quantum physics, thermodynamics, solid state physics, electromag- netism, optics, and astrophysics.
12 wrz 2022 · In the preceding section, we derived a formula for calculating the variation in pressure for a fluid in hydrostatic equilibrium. As it turns out, this is a very useful calculation. Measurements of pressure are important in daily life as well as in science and engineering applications.
