Hooke's Law and Elasticity — exam questions
12 original Incandio exam-style questions on Hooke's Law and Elasticity, 29 marks, about 29 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 Hooke's Law and Elasticity — 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
10 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
- Describe (2–4 marks)
- developed, linked statements of what happens — including a named direction where one exists
- 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
- Suggest (1–3 marks)
- a plausible answer applying taught physics to an unfamiliar arrangement
- Complete (1–4 marks)
- the missing entries in a table, circuit or diagram
- Identify (1–2 marks)
- the correct item selected from what is shown
- Determine (1–4 marks)
- a value obtained by combining a reading or gradient with a relationship
- Design (4–6 marks)
- a workable method: variables, control, measurement, repeats
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 1.23 · 1.24 · 1.22. 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 hung masses from a spring and measured its length each time. The spring was 40 mm long before any mass was added.

(1)Complete
Complete Table 1 by giving the extension at 4.0 N.
A student hung masses from a spring and measured its length each time. The spring was 40 mm long before any mass was added.

(b)
(2)Identify
Identify the reading in Table 1 at which the spring stops obeying Hooke's law, and give a reason.
A student hung masses from a spring and measured its length each time. The spring was 40 mm long before any mass was added.

(3)Determine
Determine the extension the spring would have had at 5.0 N if it had continued to obey Hooke's law.
A student hung masses from a spring and measured its length each time. The spring was 40 mm long before any mass was added.
Table 1 — the student's results Force / N Length / mm Extension / mm 0 40 0 1.0 62 22 2.0 84 44 3.0 106 66 4.0 128 to be found 5.0 162 122 ............................ mm
(d)
(3)Suggest
Suggest two changes the student could make to obtain more reliable results from this experiment.
A student hung masses from a spring and measured its length each time. The spring was 40 mm long before any mass was added.

(Total for Question 5 = 3 marks)
-
(3)Calculate
A spring obeying Hooke's law extends by 30 mm when a force of 2.4 N is applied. Calculate the extension produced by a force of 4.0 N.
............................ mm
(Total for Question 6 = 3 marks)
-
(2)Explain
Explain what has happened to a spring when its force–extension graph stops being a straight line.
(Total for Question 7 = 2 marks)
-
(3)Suggest
A student loads a spring heavily, then removes all the masses and finds it is now 5 mm longer than it was at the start. Suggest what this shows.
(Total for Question 8 = 3 marks)
-
(6)Design
Design an experiment to find the limit of proportionality of a spring.
(Total for Question 9 = 6 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 Hooke's Law and Elasticity to Ember, an AI pupil who does not have it yet and asks the awkward question.
- Defend it — argue it against Robert Hooke over three rounds, marked against descriptors you can read first.
