IGCSE Physics Formula Sheet
This IGCSE physics formula sheet lists every equation the Cambridge 0625 syllabus asks you to recall and use, from speed and density to electricity, waves and space. It covers the basic physics formulas for Core and the extra important physics formulas for Extended (Supplement) candidates.
- 34 formulas
