Speed, and What a Distance–Time Graph Is Telling You — exam questions
12 original Incandio exam-style questions on Speed, and What a Distance–Time Graph Is Telling You, 28 marks, about 28 minutes of writing. Each one carries the command word, the tariff and the specification statement it assesses, exactly as a paper presents them. This is an original Incandio practice question, written to reflect the structure and demands of the qualification. It is not an official Pearson Edexcel past-paper question.
This is the practice set for Speed, and What a Distance–Time Graph Is Telling You — the lesson that teaches it. Read the lesson first if the idea is new; come here when you want to find out whether you can turn it into marks. Completely free, no account needed to read.
What these questions ask of you
7 command words run through this set, and on Pearson Edexcel International GCSE Physics each one means something precise. Answering the wrong command is the commonest way a candidate who understands the lesson still loses the mark.
- Which (1 mark)
- one option chosen from the set given
- State what is meant by (1–2 marks)
- the definition
- Calculate (1–5 marks)
- select the equation, substitute, evaluate — and state the unit Misread as: giving a bare number with no equation and no unit
- Explain (2–4 marks)
- the physics that causes it, set out as a line of reasoning Misread as: describing the change without giving the physical reason for it
- Give (1–2 marks)
- a short factual answer
- Suggest (1–3 marks)
- a plausible answer applying taught physics to an unfamiliar arrangement
- Describe (2–4 marks)
- developed, linked statements of what happens — including a named direction where one exists
Assessed on Paper 1 (4PH1/1P) and Paper 2 (4PH1/2P), against AO1, AO2, AO3.
Where these sit in the specification
Pearson Edexcel International GCSE Physics (4PH1) — statements 1.1 · 1.4 · 1.3 · 1.5. Incandio is aligned to this specification; it is not published by, endorsed by or affiliated with Pearson, and it reproduces none of Pearson's wording.
The 12 questions
Answer them on paper, then open the lesson's exam practice to have them marked. The mark scheme, the accepted and rejected answers and the annotated model answer are in Incandio and are not printed here — an answer beside its question is not practice.
-
A student walks from home to a shop, waits there, and then walks back. Her distance from home was recorded throughout the journey.
Figure 1 — distance from home against time for the student's journey. Plotted as a line; the graph is drawn in Incandio and the readings are below. Time / s Distance from home / m 0 0 60 90 120 180 180 180 240 180 300 90 360 0 (a)
(1)Give
Give the distance of the shop from the student's home, using Figure 1.
A student walks from home to a shop, waits there, and then walks back. Her distance from home was recorded throughout the journey.

(b)
(2)Describe
Describe what Figure 1 shows about the student's motion between 120 s and 240 s.
A student walks from home to a shop, waits there, and then walks back. Her distance from home was recorded throughout the journey.
Figure 1 — distance from home against time for the student's journey. Plotted as a line; the graph is drawn in Incandio and the readings are below. Time / s Distance from home / m 0 0 60 90 120 180 180 180 240 180 300 90 360 0 (c)
(3)Calculate
Calculate the student's speed on the outward walk, using Figure 1.
A student walks from home to a shop, waits there, and then walks back. Her distance from home was recorded throughout the journey.
Figure 1 — distance from home against time for the student's journey. Plotted as a line; the graph is drawn in Incandio and the readings are below. Time / s Distance from home / m 0 0 60 90 120 180 180 180 240 180 300 90 360 0 ............................ m/s
(d)
(3)Suggest
Suggest why the student's average speed for the whole journey is much lower than the speed you calculated for the outward walk.
A student walks from home to a shop, waits there, and then walks back. Her distance from home was recorded throughout the journey.
Figure 1 — distance from home against time for the student's journey. Plotted as a line; the graph is drawn in Incandio and the readings are below. Time / s Distance from home / m 0 0 60 90 120 180 180 180 240 180 300 90 360 0 (Total for Question 1 = 9 marks)
-
(1)Which
Which is the correct unit for speed?
Unit A m B m/s C m/s² D N (Total for Question 2 = 1 mark)
-
(1)State what is meant by
State what is meant by the average speed of an object.
(Total for Question 3 = 1 mark)
-
(3)Calculate
A runner covers 400 m in 50 s. Calculate her average speed.
average speed = ............................ m/s
(Total for Question 4 = 3 marks)
-
(3)Calculate
A car travels at an average speed of 24 m/s for 15 minutes. Calculate the distance it covers.
............................ m
(Total for Question 5 = 3 marks)
-
(2)Explain
Explain what a steeper line on a distance–time graph tells you about the motion.
(Total for Question 6 = 2 marks)
-
(2)Give
Give the two measurements needed to find the average speed of a toy car rolling down a ramp.
(Total for Question 7 = 2 marks)
-
(3)Suggest
A student times a toy car over a 50 cm run and gets a speed much larger than the true value. Suggest why a short run makes this experiment unreliable.
(Total for Question 8 = 3 marks)
-
(4)Explain
Explain what the gradient of a distance–time graph represents, and what a horizontal section and a curved section each tell you about the motion.
(Total for Question 9 = 4 marks)
Have them marked, then defend the answer
Practice tells you the mark; teaching it back tells you whether you understand it. On Incandio a topic counts as mastered only once you have taught it and defended it.
- Mark these questions — 12 questions, marked on Incandio against the authored scheme, with the mistake you actually made named.
- Teach it — explain Speed, and What a Distance–Time Graph Is Telling You to Ember, an AI pupil who does not have it yet and asks the awkward question.
- Defend it — argue it against Galileo Galilei over three rounds, marked against descriptors you can read first.
