OxfordAQA IGCSE Physics: P3 Momentum and Safety

This course covers P3 Momentum and Safety from the OxfordAQA IGCSE Physics specification 9203 in full. Every lecture is built directly around the specification so there is nothing missing and nothing unnecessary.

P3 is one of the most calculation-heavy topics in IGCSE Physics and one that students consistently find difficult. Momentum calculations, conservation of momentum, and stopping distance questions appear regularly on past papers. Mastering this topic early gives you a significant advantage in the exam.

In this course you will learn what momentum is and how to calculate it using the equation p = mv. You will understand the law of conservation of momentum and apply it to collisions and explosions, including the concept of recoil. Every calculation is broken down step by step so you know exactly what to write in the exam.

The course covers stopping distances in detail, explaining the difference between thinking distance, braking distance and total stopping distance. You will learn all the factors that affect each one and understand why braking distance is proportional to speed squared. You will also explore how safety features like airbags, seatbelts, crumple zones and helmets all work using the same principle of increasing the time taken to change momentum.

A practice quiz is linked in the resources section of each lecture on supermuneeeb so you can test yourself immediately after watching.

This course is taught by Muneeb Farooq, an IGCSE Physics, Chemistry and Mathematics specialist with 8 years of teaching experience across the UK, UAE, Bahrain and Pakistan.
