What is the formula used to calculate pressure?

Pressure is defined as the force exerted per unit area over which that force is distributed. This relationship is captured by the formula Pressure = Force / Area. In this formula, pressure is measured in units such as pascals (Pa), force can be measured in newtons (N), and area in square meters (m²).

When applying this formula, it's important to understand that pressure increases when either the force increases while keeping the area constant, or when the area over which the force is distributed decreases while keeping the force constant. This is crucial in various applications, such as hydraulics, pneumatics, and material science, where understanding how pressure behaves under different conditions is essential for practical applications.

In contrast to the other options, where Force x Area, Area / Force, and Force + Area do not accurately represent the relationship between pressure, only the correct formula ensures a clear understanding of how pressure is quantified and measured in real-world scenarios.
