Revision sheet: Understanding Density and Pressure

📋 Course Outline

1. Density and pressure types

📖 1. Density and pressure types

🔑 Key Concepts & Definitions

• Density : Density is a measure of how much mass is packed into a given volume of a substance.
• Pressure : Pressure is the force applied per unit area on a surface.

⚠️ Common Pitfalls & Confusions

1. Mixing up density (mass per volume) with pressure (force per area).
2. Using the wrong unit idea: volume for density vs area for pressure.

✅ Exam Checklist

1. Define density as mass per volume and state what it tells you about a material.
2. Identify pressure as force per area and explain what increases pressure.
3. Solve a basic density question using the given mass and volume values from the test context.
