Edexcel International A-Level Physics: October 2023 Unit 4 Past Paper Walkthrough
In this video, we go through the October 2023 Edexcel International A-Level Physics Unit 4 paper: Further Mechanics, Fields, and Particles (Paper Code: WPH14/01). This is a full walkthrough covering both Sections A and B, with clear step-by-step explanations of each question and the reasoning behind the answers. Section A includes multiple-choice questions on nuclear notation, impulse and momentum, circular motion, linear accelerators, magnetic flux, Rutherford scattering, charged particles in magnetic fields, angular velocity, capacitor discharge, and motion over a humpback bridge. Section B covers a range of structured problems, including: – Rotational motion of children on a roundabout and the physics of circular motion and angular speed. – Alpha particle scattering and minimum approach distance in nuclear interactions. – RC circuit discharge and determination of capacitance from the discharge graph. – Momentum conservation and collisions in two dimensions using curling stones. – Deflection of electron beams in electric and magnetic fields and comparison of measured e/m with the known value. – Pions and muons in particle physics, involving quark structure, conservation laws in pion decay, muon mass from rest energy, and relativistic time dilation of fast-moving pions in the atmosphere. Each problem is discussed in line with the mark scheme and the official Edexcel syllabus. This walkthrough is designed to help you not only find the correct answers but understand the underlying physics concepts that connect the questions.
