DrG-Physics · Centripetal Force · Advanced Higher Physics revision (RM03)

A focused revision booklet for Advanced Higher Physics, part III of the DrG-Physics Rotational Motion series. It covers centripetal acceleration and force, vertical circles with energy, loop-the-loop, cars on roundabouts and the conical pendulum.

Every worked solution shows the relationship, the substitution and the answer with its unit, one mark at a time — the way a marker reads a script.

WHAT’S INSIDE
• Data sheet with every relationship used
• Theory with diagrams: centripetal acceleration and force; vertical circles; contexts you will meet
• Topic Traps: the three errors that cost the most marks
• Five fully worked questions:
– Q1 A horizontal circle (4 marks)
– Q2 A vertical circle with energy (11 marks)
– Q3 A car on a roundabout (6 marks)
– Q4 Loop-the-loop (5 marks)
– Q5 The conical pendulum (6 marks)
• Examiner’s note and Do / Don’t panel after every question
• Formula card and revision checklist

TWO EDITIONS IN ONE DOWNLOAD
• STUDY edition — every step has a “why” note explaining the reasoning
• EXAM edition — the same solutions, lean and exam-shaped

Written by Dr Godoy (Dr G), a GTCS-registered physics teacher. All questions are original and written to the current Qualifications Scotland Advanced Higher Physics specification (formerly SQA).
