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.
Learn what pressure is, how to calculate it, and what are the different types of pressure. See examples, videos, and solved problems on pressure and its effects on fluids and solids.
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. It is the ratio of the force applied to the surface area over which the force is applied. We can define pressure as:
- 5 min
- The force applied perpendicular to the surface of an object per unit area over which that force is distributed is known as pressure.
- The push or pull on an object with mass that causes it to change its velocity is known as force.
- A pascal can be defined as a force of one newton applied over a surface area of a one-meter square.
- The fluid exerts pressure in all directions because the particles in the fluid can move in all directions. The movement of these molecules results...
- We know that the temperature of the gas is proportional to the average kinetic energy of the molecules. As the kinetic energy increases, the collis...

Apr 25, 2024 · Pressure is defined as the force applied per unit area on the surface of an object. It is commonly measured in units of pascals (Pa) or pounds per square inch (psi). Pressure indicates how much force is exerted over a specific area and is a key concept in both physics and engineering.
