1. What is the Pressure Formula?

Definition: Pressure is defined as the force applied perpendicular to the surface of an object per unit area.

Purpose: This calculator helps students understand the relationship between force, area, and pressure in physics.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Pressure (Pascals)
• \( F \) — Force (Newtons)
• \( A \) — Area (square meters)

Explanation: Pressure increases with greater force or smaller contact area.

3. Importance of Pressure Calculation

Details: Understanding pressure is crucial for designing structures, hydraulic systems, and understanding everyday phenomena.

4. Using the Calculator

Tips: Enter the force in Newtons and area in square meters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the SI unit of pressure?
A: The SI unit of pressure is Pascal (Pa), which equals 1 Newton per square meter.

Q2: How does area affect pressure?
A: Pressure is inversely proportional to area - smaller contact area means greater pressure for the same force.

Q3: What are some real-life examples?
A: Sharp knives cut better (small area), snowshoes prevent sinking (large area), hydraulic brakes transmit force through fluid pressure.

Q4: How is this different from force?
A: Force is the total push or pull, while pressure is how concentrated that force is over an area.

Q5: What if my area is in cm²?
A: Convert to m² first (1 m² = 10,000 cm²) for correct Pascal calculation.
