Pressure Formula:
From: | To: |
Definition: This formula calculates pressure as the force applied per unit area.
Purpose: It helps students and professionals understand and calculate pressure in various physics and engineering applications.
The formula is expressed as:
Where:
Explanation: Pressure increases with greater force or smaller contact area. It's a fundamental concept in fluid mechanics and material science.
Details: Understanding pressure is crucial for designing structures, hydraulic systems, and understanding atmospheric phenomena.
Tips: Enter the force in Newtons and area in square meters. Both values must be positive (area must be > 0).
Q1: What are the standard units in this formula?
A: The SI units are Pascals (Pa) for pressure, Newtons (N) for force, and square meters (m²) for area.
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's a practical example of this formula?
A: Sharp knives work because the small blade area creates high pressure for cutting with less force.
Q4: How do I convert other units to these standard units?
A: 1 kPa = 1000 Pa, 1 N = 1 kg·m/s², 1 m² = 10,000 cm². Use our unit converters if needed.
Q5: What's the difference between force and pressure?
A: Force is the total push/pull, while pressure is force distributed over an area (force per unit area).
