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
Calculate a gradientCalculate the gradient using A and B, in m s⁻¹. It gives the object's velocity. Give your answer to 3 significant figures.

Graph values
| Point | Time / s | Displacement / m |
|---|---|---|
| A | 10 | 4 |
| B | 30 | 8 |
Treat the displayed values as exact unless an uncertainty is stated.
Hint
Gradient = (vertical change) / (horizontal change). Use the same order for both subtractions; a falling line has a negative gradient.
Worked solution
- A = (10 s, 4 m); B = (30 s, 8 m).
- Gradient = (8 − 4) / (30 − 10) = 0.2 m s⁻¹.
- Answer: 0.200 m s⁻¹ (3 significant figures).
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.
