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. The IUPAC recommendation for pressure is a lower-case p. However, upper-case P is widely used.
Jul 18, 2024 · Pressure, in the physical sciences, perpendicular force per unit area, or the stress at a point within a confined fluid.
The meaning of PRESSURE is the burden of physical or mental distress. How to use pressure in a sentence.
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). In other words, you might be safe lying on a bed of nails if the total surface area of all the nail tips together is large enough. Really?
Dec 28, 2020 · Pressure is a key concept in physics, whether you're interested in how meteorologists predict the weather, or you want to describe the Carnot cycle in thermodynamics. Pressure is the force on a surface per unit area, and it has a close link to the temperature of the liquid or gas creating it.
Feb 20, 2022 · 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 \(1\, Pa = 1 \space N/m^2\).
a difficult situation that makes you feel worried or unhappy: She's got a lot of pressure on her at work just now. Be nice to him - he's been under a lot of pressure recently. Can you work well under pressure? the pressures of work. so no pressure then! humorous.
Pressure definition: the exertion of force upon a surface by an object, fluid, etc., in contact with it. See examples of PRESSURE used in a sentence.
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.
May 7, 2019 · Pressure Definition, Units, and Examples. What Pressure Means in Science. In science, pressure is a measurement of the force per unit area. The SI unit of pressure is the pascal (Pa), which is equivalent to N/m 2 (newtons per meter squared).
