The 8 most common kinematics mistakes students make on motion graph questions — and how to diagnose them before the exam does. Based on physics education research (Arons, Knight, Chabay & Sherwood), each trap includes: what the student typically says, what it reveals about their thinking, what to look for in their work, and how to fix it. Covers position-time graphs, velocity-time graphs, displacement vs distance, average vs instantaneous velocity, chord vs tangent confusion, and more. Designed as a teacher diagnostic tool — use it to identify conceptual gaps before mock exams. Includes a student self-check checklist. Suitable for IB Physics (Topic 2.1), AP Physics 1 (Unit 1), A-Level Mechanics, GCSE and IGCSE Motion. Free to share with colleagues.
