International GCSE Physics Paper 1 dated Thursday 8 November 2018 assesses core concepts across energy transfer, thermal radiation, magnetism, and resistive behaviour of an LDR. The exam requires practical calculation of electrical energy and cost, interpretation of heat-transfer features, and classification of electromagnetic radiation at temperature. It also tests understanding of magnetic field patterns and forces, investigation design for an electromagnet, and circuit/data-logging methods to analyse resistance versus light intensity over a 24-hour period.

FAQs

What materials are required for International GCSE Physics Paper 1?

You must have a ruler, a scientific calculator, and the Physics Equations Sheet (enclosed).

What is the purpose of recording LDR resistance every second in Question 3.3?

Recording every second gives a much more detailed time-series dataset, improving how accurately changes in resistance across the 24 hours can be observed and explained.
