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 on CIE IGCSE Physics Physical quantities and measurement techniques, covering Physical quantities and measurement techniques. Each one builds up to exam-style questions. Build a strong foundation in mechanics and electricity before tackling the more mathematically demanding astrophysics and nuclear topics.
