The document is a GCSE (9–1) Combined Science (Physics) A past paper, assessing key physics concepts. It includes topics such as waves (properties, refraction, and speed), electricity (transformers, circuits), energy transfer (potential and kinetic energy, thermal energy), and motion (stopping distance, acceleration). It also covers radioactivity (decay equations, types of radiation) and practical investigations (e.g., ripple tanks, hot plate experiments). The paper emphasizes problem-solving, data interpretation, and the application of theoretical knowledge to real-world and experimental contexts.
