Pressure and pressure differences in fluids (physics only)
Question
- A. Pressure = Force / Area — graph focus for pressure
- B. This confuses force and pressure and does not answer Pressure on a surface (physics only).
- C. This is too vague because it does not use the force or motion quantity named in the objective.
- D. This reverses the physical cause and effect for Pressure and pressure differences in fluids (physics only).
Answer
The correct answer is: Pressure = Force / Area — graph focus for pressure
Explanation
The correct option is Pressure = Force / Area — graph focus for pressure. Pressure = Force / Area — graph focus for pressure is correct because it matches the approved learning objective to (Physics only) Use the equation pressure = force normal to a surface divided by area of that surface. This answer belongs to Pressure on a surface (physics only) within Pressure and pressure differences in fluids (physics only), so it must use precise AQA GCSE Physics forces and motion vocabulary. The other options are wrong because they either confuse force and pressure, omit the required force or motion condition, or move away from the exact subtopic being tested.
Common mistake
Misunderstanding Pressure Calculation
Students often confuse the formula for pressure, mistakenly using pressure = area / force instead of pressure = force / area.
Remember that pressure is defined as force applied per unit area. Always use the correct formula: pressure = force normal to a surface divided by area.
