Question 1
The graph shows how the velocity v of a cyclist moving in a straight line varies with time t. What is the cyclist's average velocity over the 12 s?
Physics practice questions by topic, in exam style
Original questions for every topic, written in the style of Paper 1A, 1B and 2 and marked with full working. Pick a theme, work through it untimed, then try a timed set at Paper 1A pace.
| Paper 1A | Multiple choice, about 2 minutes a question in our timed sets |
|---|---|
| Paper 1B | Data-based questions: tables, graphs and uncertainties |
| Paper 2 | Short-answer and extended-response questions |
| Levels | Every question is tagged SL or HL |
How to use topic practice
- Untimed first: work each question in full, then compare every line with the worked solution.
- Then timed: sets of 5 or 10 multiple-choice questions at about two minutes each.
- Structured questions: type each value in the unit shown; the answer is checked within a sensible tolerance and your significant figures are noted.
- Finish with a full Paper 1 practice paper at your level, in the 1.5 or 2 hours of the real paper.
Past papers and our questions
Past papers are the IB's own; ask your school for them. Ours are original questions written for the current course, by topic, so you can drill a weak theme and save past papers for full timed practice.

Question 2
A 0.20 kg sample of a solid is heated by a 50 W heater. All the energy from the heater goes into the sample. The graph shows the temperature θ of the sample against time t. What is the specific latent heat of fusion of the solid?
Question 3
A ray of light passes from air into glass of refractive index 1.50, meeting the boundary at an angle of incidence of 40°, as shown. What is the angle of refraction?
Question 4
The diagram shows the electric field lines around two point charges X and Y. What can be deduced about the charges?
Question 5
The diagram shows some energy levels of an atom. What is the wavelength of the photon emitted when an electron moves from the −3.7 eV level to the −10.4 eV level?

Questions people ask
Where can I find IB Physics questions by topic?
Our practice is arranged by theme and topic for the current course, with Paper 1A multiple choice and Paper 1B and Paper 2 structured questions, each worked in full.
Are older past papers useful?
The current course was first assessed in 2025 and is organised in five themes, A to E. Check each older question against the current themes and topics before you rely on it.
How should I time Paper 1A practice?
About two minutes a question works for our timed sets, leaving time for Paper 1B within the 1.5 hours at SL or 2 hours at HL.
