GCSE Physics equations practice
Select a relationship from the equation sheet, rearrange it and calculate with the right units.
GCSE Physics graph questions
Read scales, plot coordinates and interpret straight-line gradients and intercepts.
Practise
Choose axesA resistor obeys V = IR. Choose axes so the gradient gives resistance directly.
Data to plot
| Point | Current / A | Potential difference / V |
|---|---|---|
| 1 | 0.02 | 1.2 |
| 2 | 0.04 | 2.4 |
| 3 | 0.06 | 3.6 |
| 4 | 0.08 | 4.8 |
Hint
Compare V = IR with y = mx. The coefficient of the horizontal quantity is the gradient.
Worked solution
- Rule: Horizontal: current / A; vertical: potential difference / V.
- Plot potential difference vertically against current horizontally.
- Gradient = ΔV / ΔI, with units V A⁻¹ = Ω.
Question type: Mixed practice

Foundation and Higher: this set covers content common to both tiers. Some calculations need several steps.
Reading a graph
Read the axis quantities and units before calculating. Use two well-separated points on the supplied line for a gradient. The gradient’s meaning comes from the axes: displacement divided by time gives velocity; potential difference divided by current gives resistance. These tasks use straight lines and coordinate entry; tangents and areas under curves are outside this set.
