2025年1月17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.

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.

The meaning of PRESSURE is the burden of physical or mental distress. How to use pressure in a sentence.

2020年12月28日 · Learning the precise definition of pressure helps you understand key concepts related to gases, thermodynamics, buoyancy and much more. Pressure is simply defined as the amount of force per unit area . The key point when you're trying to understand pressure is to think about what happens on the atomic level in a liquid or gas at high pressure.

2022年5月6日 · Pressure is defined as a measure of the force applied over a unit area. Pressure is often expressed in units of Pascals (Pa), newtons per square meter (N/m 2 or kg/m·s 2), or pounds per square inch. Other units include the atmosphere (atm), torr, bar, and meters sea water (msw). What Is Pressure? Pressure is force per unit area.

Pressure is also the force that is put on a surface with reference to the area of the surface. [ C ] Competitive pressures will force the company to sell off its factories. [ U ] They put a lot of …

Pressure is defined as the force applied at the right angles to the surface of an object per unit area over which that force is distributed. There are specified sensors to measure the different types of pressure. SI unit of pressure is pascal (Pa) and is denoted by the letter ‘p’. Pressure is a scalar quantity. It is given by the formula:

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.

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.

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.
