## What is meant by pressure in physics?

pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid.

## What is the formula for calculating pressure?

P = F/A

Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A. Because pressure is force divided by area, its meter-kilogram-second (MKS) units are newtons per square meter, or N/m2.

**How is pressure defined in physics?**

**What is pressure give example?**

Pressure is defined as the force acting on a unit area of a surface is called pressure. Example : 1) Air pressure in car tyre supports the weight of the car. 2) Aircraft fly because of the pressure on the wings. 3) Sucking a drink through straw – fluids flow because of pressure difference.

### What is the pressure in physics?

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.

### How is pressure affected by force?

When a force is exerted on an object it can change the object’s speed, direction of movement or shape. Pressure is a measure of how much force is acting upon an area. Pressure can be found using the equation pressure = force / area. Therefore, a force acting over a smaller area will create more pressure.

**What factors affect the pressure of an object?**

Pressure depends on two factors: The magnitude of force applied – the greater the force, the greater is its effect. The area over which the force is applied, i.e. the area of contact between the two objects.

**What are the factors affecting liquid pressure write the mathematical equation?**

The height of the liquid column is ′h′, density of liquid ′d′ and acceleration due to gravity ′g′ are factors. The equation is liquid pressure p=hdg.

## What are examples of pressure in solids?

Answer: Though solid extert pressure the most interesting examples of pressure involve fluid that is gas and liquid and in particular water and air.
