# What is the relationship between pressure, force, and area in physics?

## What is the formula to calculate pressure in physics?

A. P = F/A

B. P = A/F

C. P = F * A

## What units are commonly used to measure pressure?

A. pounds

B. inches squared

C. pounds per square inch (psi)

## Answer:

The formula to calculate pressure in physics is P = F/A. The units commonly used to measure pressure are pounds per square inch (psi).

**Explanation:** Pressure in physics is defined as the force applied perpendicular to the surface of an object per unit area. The formula to calculate pressure is P = F/A, where P is the pressure, F is the force applied, and A is the area over which the force is distributed.

For example, if a force of 100 pounds is applied over an area of 10 square inches, the pressure can be calculated as follows:

P = F/A

P = 100 lb / 10 in²

P = 10 psi

Therefore, the pressure exerted in this example is 10 pounds per square inch (psi), which indicates the amount of force distributed over a unit area.
