The formulae you are given and the ones you must learn. Knowing which is which is worth marks.

What it is
Physics papers include an equation sheet with some formulae. Others must be recalled from memory, and specifications list exactly which.
Where it applies
GCSE physics and combined science.
How it works
Each equation states a relationship between measured quantities, and each quantity has a unit. The method is always the same: write the equation, rearrange, substitute, calculate, state the unit.
How to use it in your work
Find out which equations you must recall and learn those first — every year students lose marks on formulae that were never going to be on the sheet.
Rearrange BEFORE substituting numbers. It is far less error-prone.
Write the equation down even if you get the arithmetic wrong. That line alone earns a method mark.
Units are marks. Every time.
Where to get help
Your teacher, your board's specification for the depth required at your tier, and Bitesize for the diagrams. The subject song runs the topics in order.
Revise this with a song
These are ours. We write revision songs because a lot of people remember a tune when they cannot remember a page, and because revising out loud in the kitchen beats staring at a highlighter.
