Revision portal
GCSE Physics
Topic maps, in-depth guides and exam-style practice — organised by the same strands your course uses. Browse by area below or jump into a featured guide.
Revise by topic area
Each area links to a dedicated hub with every guide we publish in that strand — plus a shortcut to the full curriculum list.
Required practicals
Exam-board aligned guides: aim, method, variables, equipment, common mistakes and how to interpret results in the exam — grouped by topic on the hub.
Resistance & I–V graphs
To measure current through and potential difference across a resistor (or lamp), calculate resistance, and plot I–V to identify ohmic vs non-ohmic behaviour.
Water waves / wave properties
To measure wave speed using v = fλ by finding wavelength and frequency from a wave source.
Density of solids
To calculate density ρ = m/V using a balance and displacement method for irregular objects or ruler/caliper for regular blocks.
Featured guides
Energy
Energy Stores & Transfers
Energy Stores & Transfers is one of the most important GCSE Physics routes because it teaches you how to describe change precisely.
Energy
Work Done
Work is done whenever a force causes an object to move.
Energy
Power
Power is the rate at which work is done, or the rate at which energy is transferred.
Energy
Efficiency
Efficiency is a measure of how much useful energy you get out of a device compared to the total energy you put in.
Energy
National & Global Energy Resources
National and global energy resources are the sources from which we generate electricity.
Energy
Specific Heat Capacity
Specific heat capacity is the amount of energy required to raise the temperature of 1kg of a substance by 1°C.
Energy
Energy Changes in Systems
Energy changes in a system describe how energy is transferred and transformed.
Electricity
Current, Voltage & Resistance
Current, Voltage & Resistance is a Physics topic where definition mix-ups cause most of the damage.
How to use this hub
- Pick a topic area you are weakest on — use your mocks or class tests to decide.
- Read the guide, then attempt practice questions without looking back at notes.
- Review mistakes using our mistake prompts, then move to the next guide in the same area.
