Pressure tells us how much force is applied over a certain area. The formula for pressure is:

P=F/A

Where:

• P (Pressure, in Pascals, Pa) → How much force is applied per unit area.

• F (Force, in Newtons, N) → The total force pushing down.

• A (Area, in square meters, m²) → The surface over which the force is applied.

Example Calculation:

Let’s say you press a 100 N force on a 2 m² surface.

P=100/2=50 Pa

So, the pressure is 50 Pascals (Pa).

Key Things to Remember:

1. More force → More pressure.

2. More area → Less pressure. (That’s why wide tires sink less in the sand!)

3. Pressure is measured in Pascals (Pa), where 1 Pa = 1 N/m².
