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 | Definition, Measurement, & Types | Britannica
2024年12月5日 · 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.
What is Pressure? Definition, Formula, Unit, Examples - Toppr
Pressure is defined as the physical force exerted on an object. The force applied is perpendicular to the surface of objects per unit area. The basic formula for pressure is F/A (Force per unit area). Unit of pressure is Pascals (Pa). Types of Pressures are Absolute, Atmospheric, Differential, and Gauge Pressure.

Pressure: Definition, Types of Pressures and Examples - Toppr
The pressure is a physical quantity that actually depends on both the force applied on a body and the amount of surface area involved in the process.The pressure is defined as the perpendicular force applied on a surface of an object or by an object per unit area which is in contact.
What Is Pressure? - Unifyphysics
In physics, pressure is the measure of the force exerted on a surface area. Here’s a simple breakdown: Force: Think of it as a push or a pull. When you press your hand against a wall, you’re applying force to it.
11.3: Pressure - Physics LibreTexts
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). These are only two of many examples of pressures in fluids.
What Is Pressure? | Mini Physics - Free Physics Notes
Pressure (p) is defined as the perpendicular force (F) acting on unit area of a surface or the force per unit area (A). SI unit of pressure is the pascal or newton per metre square. (Pa or ) It is a scalar quantity. Pressure is deemed a scalar quantity as its calculation involves solely the force that acts perpendicular to the contact area.
