Ultrasound

OCR·GCSE

Ultrasound (Topic 4.9) explores how sound waves above 20,000 Hz are used in medical imaging and sonar through the principle of partial reflection at boundaries between media of different densities. Mastery of this topic requires candidates to perform precise echo-sounding calculations using d = v × t/2, apply correct scientific language in extended answers, and evaluate ultrasound against X-rays — skills that appear in both Foundation and Higher tier papers and carry marks across all three assessment objectives.

Weight vs Mass

Pearson Edexcel·GCSE

Weight and Mass are two of the most frequently confused concepts in GCSE Physics, yet the distinction is straightforward once you understand it — and examiners reward candidates who can articulate it precisely. This topic covers the definitions of mass (quantity of matter, measured in kg) and weight (force due to gravity, measured in N), the formula W = mg, and why weight varies across planets while mass remains constant. Mastering this topic unlocks marks across AO1 definitions, AO2 calculations, and AO3 evaluation questions throughout the specification.
