- Pressure - Wikipedia
Pressure is the amount of force applied perpendicular to the surface of an object per unit area The symbol for it is "p" or P [2] The IUPAC recommendation for pressure is a lower-case p [3] However, upper-case P is widely used

pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid The pressure exerted on a floor by a 42-pound box the bottom of which has an area of 84 square inches is equal to the force divided by the area over which it is exerted; i e , it is one-half pound per square inch
- Pressure (Physics): Definition, Units, Formula Examples
Pressure is one of the most important concepts in physics While you'll undoubtedly have some idea of what pressure is from things like atmospheric pressure readings given in weather reports or water pressure in your home's heating system, when you're studying physics, the details really matter
- 11. 3: Pressure - Physics LibreTexts
Pressure is the force per unit perpendicular area over which the force is applied In equation form, pressure is defined as \(F=PA\) The SI unit of pressure is pascal and \(1\, Pa = 1 \space N m^2\)

What is Pressure? Have you ever wondered why our knives need to be so sharp or why the nails we use the end with a sharp point? The answers to all these questions lie in the concept of pressure
- Pressure Definition in Science - Science Notes and Projects
Pressure is a derived unit of measurement The SI unit of pressure is the pascal (Pa) which is newtons per square meter (N m 2) Other common units include pounds per square inch (psi), atmospheres (atm), torr, and millimeters of mercury (mm Hg) The pressure formula is normal force per unit area
- What is Pressure? - GeeksforGeeks
Pressure is defined as the force applied perpendicular to the surface of an object, divided by the area over which the force is distributed The force of 'F' Newton is applied perpendicularly to the surface area 'A' Then the formula that is used to calculate the pressure acting on an area is, P = F A where,
