This topic is examined in Edexcel 1PH0/1 (Paper 1, Foundation or Higher tier). Edexcel uses scenario-based questions (e.g. "A skydiver falls from a plane…") and tests the chain of reasoning from imbalanced forces to terminal velocity. Questions often include v-t graph interpretation.
Most Common Question Types
- Describe and explain why a falling object reaches terminal velocity [3-4 marks] — requires a sequence: weight > drag → accelerates → drag increases → resultant force decreases → eventually weight = drag → resultant = 0 → constant velocity
- Sketch or annotate a velocity-time graph for a falling object (or skydiver opening parachute) [3 marks]
- Explain the effect of a change (e.g. heavier object, parachute opens) on terminal velocity [2-3 marks]
- Read off acceleration from a v-t graph gradient or distance from area under graph [2 marks]
What Examiners Want to See
For "explain terminal velocity" questions, examiners want a chain of reasoning that links force → acceleration → velocity → drag → resultant force → terminal velocity. Use the phrase "resultant force" and reference Newton's Second Law (F = ma) explicitly.
This exam focus covers Exam Focus — Terminal Velocity within Terminal Velocity for GCSE Physics. Revise Terminal Velocity in Extra Topics for GCSE Physics with 13 exam-style questions and 11 flashcards. Use this page as part of a wider topic revision path rather than treating it as an isolated fact. It is section 11 of 13 in this topic. Treat this as a marking guide for what examiners are looking for, not just a fact list.
Practice questions for Terminal Velocity
An object reaches terminal velocity when falling through air. Which statement correctly describes the forces at terminal velocity?
Explain how a skydiver reaches terminal velocity after jumping from a plane. Include changes to forces and acceleration in your answer.
