Thermodynamics. Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. [1] : 445 Gauge pressure (also spelled gage pressure) [a] is the pressure relative to the ambient pressure. Various units are used to express pressure.
Apr 2, 2024 · 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.
To make this concept precise, we use the idea of pressure. Pressure is defined to be the amount of force exerted per area. P = F A. So to create a large amount of pressure, you can either exert a large force or exert a force over a small area (or do both).
pressure: [noun] the burden of physical or mental distress. the constraint of circumstance : the weight of social or economic imposition.
Feb 20, 2022 · Definition: Pressure. Pressure is defined as the force divided by the area perpendicular to the force over which the force is applied, or. P = F A. (11.3.1) (11.3.1) P = F A. where F F is a force applied to an area A A that is perpendicular to the force. A given force can have a significantly different effect depending on the area over which ...
pressure. buoyancy …. The Physics Hypertextbook. ©1998–2024 Glenn Elert. Author, Illustrator, Webmaster. A solid in contact with a fluid experiences a force all over its outer surface. Pressure is the ratio of the force applied to the area over which it is exerted.
