Physics study notes and revision guide
What Physics covers
Physics uses models, measurements and mathematical relationships to explain the natural world. Many topics become clearer when you sketch the situation before choosing an equation. A useful set of notes states the physical idea, defines every symbol, gives the units and includes a worked example. The aim is not to memorise a long list of formulas in isolation; it is to recognise which principle applies and explain why the result is reasonable.
How Physics is usually assessed
Physics assessments commonly combine short knowledge questions, calculations, explanations, graph interpretation and practical skills. You may be asked to rearrange an equation, estimate a value from a graph, compare two situations or explain an observation using a model. Show substitutions and units so that your method can be followed. Practical questions often focus on variables, measurement technique, repeat readings and the limitations of the method.
Topic checklist
Use this checklist as a starting point, then compare it with your own course specification. Not every exam board includes every topic in the same way.
- Motion, speed, velocity, acceleration and motion graphs
- Forces, momentum, moments and pressure
- Energy stores, transfers, work, power and efficiency
- Thermal physics, particle models and changes of state
- Waves, sound, light and electromagnetic radiation
- Electric circuits, current, potential difference and resistance
- Magnetism, electromagnetism and motor effects where included
- Atomic or space physics, practical measurements and uncertainty
Common mistakes to avoid
- Choosing an equation because it looks familiar rather than because it fits.
- Mixing units such as centimetres and metres in one calculation.
- Confusing scalar quantities with vector quantities.
- Describing a graph trend without referring to its axes or scale.
A sample week of study
Move these tasks around to fit lessons, homework and other commitments.
- Monday: Review one motion or force idea and draw the situation.
- Tuesday: Practise calculations with substitutions and units shown.
- Wednesday: Explain one energy, thermal or wave process in complete sentences.
- Thursday: Work through a circuit or magnetism diagram and label directions.
- Friday: Complete a timed mixed set and check whether each answer is physically sensible.
Review what felt difficult, ask a specific question and adjust next week's plan.
