Quantities, units, and complete measurements
Quantities, units, and complete measurements
Physics uses physical quantities such as length, time, mass and temperature to describe the world. A measurement is written as a number with a unit, for example 2.5 m2.5 \, \text{m}2.5m or 12 s12 \, \text{s}12s.
Step-by-step lessons covering CIE IGCSE Physics Physical quantities and measurement techniques for Core and Extended tier. Each lesson breaks down Physical quantities and measurement techniques, then works through exam-style questions in Paper 1 and Paper 3 (Core) or Paper 2 and Paper 4 (Extended), plus Paper 5 or Paper 6 format. Build a strong foundation in mechanics and electricity before tackling the more mathematically demanding astrophysics and nuclear topics.
