Since students are given the equation sheet in the exam, it’s tempting to think calculations should be easy marks. They aren’t. The marks go on choosing the right equation, converting units, rearranging, and slips that examiners flag year after year.
A mistake examiners keep seeing
A current of 2.0 A flows through a 15 Ω resistor. Calculate the power.
The correct answer is P = I²R = 2.0² × 15 = 4.0 × 15 = 60 W. But a lot of students write 2.0 × 15 = 30 W, because they forget to square the current. AQA’s examiners’ reports call this out by name. Another favourite is using s = vt when the speed is changing.
These aren’t gaps in understanding. They’re habits, and habits are fixed by practice with feedback.
Three slides per equation
The Every Equation PowerPoint covers all 34 equations on the AQA GCSE Physics (8463) and Combined Science: Trilogy (8464) equation sheets. Each equation gets three slides:
- Learn: the equation, every rearranged form, what each symbol means with its unit, a FIFA worked example and a top tip.
- Practise: three questions, from warm-up to stretch, almost always with a unit conversion in the set.
- Check: answers with full working, and on most answer slides a common mistake from the examiners’ reports.
Then the harder stuff
Grade 6–9 questions rarely use one equation. There are 15 multi-step problems that chain two or three equations together, each with a “plan it” slide before the step-by-step solution, so students learn to map the route before they start calculating.
Labelled for your course
Every equation is tagged Physics + Combined or Physics only, Higher tier only, and Paper 1 or Paper 2. There’s a one-slide checklist for Combined Science and a slide of the seven Physics-only extras, plus slides on units and prefixes and on what the equation sheet means for exams in 2026, 2027 and from 2028.
How to use it
It’s fully interactive in slideshow mode: tap a topic, jump to any equation, and move between Learn, Practise and Check with one click. Teachers can use it on the board for whole-class teaching; students can work through it alone for homework or revision. For printed practice instead, the Equations Workbook is the paper version.
The full PowerPoint has 147 slides and costs £8. The free sample has 29 slides: three complete equations, two multi-step problems, the checklists and all the menus.
