Work Done — exam questions
11 original Incandio exam-style questions on Work Done, 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 Work Done — 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 (1 mark)
- one precise fact or 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
- Determine (1–4 marks)
- a value obtained by combining a reading or gradient with a relationship
- 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
- Describe (2–4 marks)
- developed, linked statements of what happens — including a named direction where one exists
- Suggest (1–3 marks)
- a plausible answer applying taught physics to an unfamiliar arrangement
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 4.11 · 4.12. 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 11 questions

-
A crate is moved from the ground into the back of a van, 1.2 m above it, in two ways. First it is lifted vertically by a hoist. Then an identical crate is pushed up a 4.0 m ramp that reaches the same height. The class measured the force needed and the distance moved in each case.
Table 1 — force and distance for the two methods Method Force needed / N Distance moved / m Lifted vertically by the hoist 600 1.2 Pushed up the ramp 225 4.0 (a)
(2)Calculate
Calculate the work done by the hoist in lifting the crate, using Table 1.

(c)
(3)Explain
Explain why more work is done pushing the crate up the ramp than lifting it, even though it ends up in the same place.

(1)Which
Which quantity is found by multiplying a force by the distance moved in the direction of that force?
Quantity A power B pressure C momentum D work done (Total for Question 2 = 1 mark)
-
(1)State
State the relationship between the work done on an object and the energy transferred to it.
(Total for Question 3 = 1 mark)
-
(3)Calculate
A gardener pushes a wheelbarrow 18 m along a path with a horizontal force of 95 N. Calculate the work done.
work done = ............................ J

(3)Determine
A winch transfers 5400 J of energy while pulling a sledge with a steady force of 360 N. Determine how far the sledge moved.

(3)Explain
A student holds a heavy box at arm's length without moving for two minutes. Explain why no work is done on the box.
(Total for Question 6 = 3 marks)
-
(3)Describe
Describe the energy transfers that take place while a crate is dragged at a steady speed across a rough floor.
(Total for Question 7 = 3 marks)
-
(3)Suggest
Suggest why a cyclist has to keep pedalling to hold a steady speed on level ground, even though her kinetic energy is not changing.
(Total for Question 8 = 3 marks)
-
(4)Explain
A person carries a heavy box horizontally across a room at a steady speed. Explain why no work is done on the box against gravity, even though the person becomes tired.
(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 — 11 questions, marked on Incandio against the authored scheme, with the mistake you actually made named.
- Teach it — explain Work Done to Ember, an AI pupil who does not have it yet and asks the awkward question.
- Defend it — argue it against James Prescott Joule over three rounds, marked against descriptors you can read first.
