• A-Level 9702 Physics Topic by Topic

This page will contains links of the worked solutions for the different chapters in the A-Level 9702 syllabus.

Some of you have been asking for this classification for some time.

Links are already available for various years and variants of the papers at the following links:

• Older papers (pre-2016 syllabus change)
• Recent papers (post-2016 syllabus change)

This page provides a chapter-wise classification of the questions asked.

Now, you can use the worked solutions for other purposes such as revising and mastering each chapter as you go on with your studies, even if you will not be sitting for the exams soon. You may also use these as an extension to the questions given to you in classes so that to further your understanding of the chapters and test yourself.

It remains up to you to see how to best use the resources provided here.


Note that the questions available in these categories do not yet include the 1100+ questions solved at the 'Doubt' pages. (It is hoped that, with time, these questions will be added.) More explanations are being made and added under each topic. With time, the amount of questions available under each category will keep on increasing as more questions are solved.


Links for the topics are provided below.

1. Physical Quantities and Units
2. Measurement techniques
3. Kinematics
4. Dynamics
5. Forces, Density and Pressure
6. Work, Energy and Power
7. Motion in a circle (Note: most questions on circular motion come along with questions on Gravitational fields)
8. Gravitational fields
9. Deformation of Solids
10. Ideal gases
11. Temperature (Note: questions on temperature are part of questions on Ideal gases and Thermal properties of materials)
12. Thermal properties of materials
13. Oscillations
14. Waves
15. Superposition
16. Communication
17. Electric fields
18. Capacitance
19. Current of Electricity
20. D.C. circuits
21. Electronics
22. Magnetic fields
23. Electromagnetic induction
24. Alternating currents
25. Quantum Physics
26. Particle and Nuclear Physics


Note that links for the topics are also present in the sidebar on the left of each page, under the label 'A-Level 9702 Topic by Topic'. The number of questions solved is indicated in bracket next to each topic.

At the end of each topic, press on 'Older post' to view more questions.

• How do you want us to proceed? Your opinions?

It has been a while since we have made such a post. Now that the October / November exams are over, we would like to take the opportunity to listen to you.


The blog is being viewed thousands of times daily by people all around the world and we hope that it is of benefit to you. But now, we want to hear your opinions:

• Is it really useful to you?
• Are you having any difficulties with the blog?
• Do you have any idea that you would like us to work on in this blog?
• Any proposition on how to improve ourselves and the content?
• Is there any other subjects, papers ... that you want us to add?
• Anything that you would like to talk regarding the blog...

We are currently working to build up a page with links to different topics of the syllabus that both teachers and students can make use of.


We would also like to remind you of  post made previously: Your Participation. You are most welcome to participate and help people from various countries around the globe in their studies. Refer to the link provided.

For example, if you have just completed your exams and want to share your own worked solutions for Mathematics for instance. You are most welcome to send us the (scanned or typed) files by mail (at physics.ref.mail@gmail.com) and we will try to publish them (as long as the solutions are correct).

This is only one way. You are free to help in any way you feel is worthy.



We are really looking forward to your views so that it helps us provide better content to you. Let us build a better online community together.
Comment and participate below.

• Participating to Physics Reference blog

The admin of 'Physics Reference' blog is pleased to inform you that you are welcomed to participate to the blog as from now. This initiative has been taken to provide the viewers with a wider variety of resources and this requires the participation of many.


You should consider the following if you intend to participate:

• How can I participate?

You can participate by providing notes (full notes, chapterwise, concept, summary notes, revision notes, concept maps, ...), worked solutions (a complete paper to a single question - in the same format as those provided by Physics Reference), articles, research works, .... (anything that you think may help the others)

• Levels

Your participation is not limited to A-Levels. It can be from O-Level, IGCSE, A-Level, University and any level that you wish.

• Subjects

Again, the subject is not limited to Physics only. You are encouraged to help in whichever subject (science or not) you are confident. As for Physics worked solutions for A-Level, you may leave paper 1, 2 and 4 to the admin of Physics Reference, as has been the case before. You mat participate in any other than these 3 papers for worked solutions.

• Some rules that you need to follow:

- You are not allowed to provide copyrighted materials. If ever i portion of text is taken from a book, ... a reference should be made to them.
- It should be TYPED in a Word document (softcopy), unless it's a diagram, illustration, ... Scanned pages are not recommended.
- Ensure that the information you are providing is correct, accurate and reliable.
- Include you name and country in the file so that the work is credited to you. The blog is viewed by people around the globe so I would like to properly credit anyone who has participated.
- Inform us which subject you will be working (through the comment box) on if you are willing to participate. This would prevent different people from doing the same work.
- The final work should be submitted to physics.ref.mail@gmail.com
- The admin of Physics Reference reserves the right to accept, reject (this usually won't be the case if your work is correct) or modify the content of your work so that it fits the viewers.
- After the work has been published, you are encourage to come back regularly to answer the queries of the viewers and clarify their doubts about your work.
- By participating, you are agreeing that the work is now a property of the admin of Physics Reference. You are not allowed to post the same work elsewhere online.





The 'Physics Reference' is being viewed by more and more people and the number of queries keeps on increasing. A single person won't be enough to help these viewers. It is hoped that many of you will participate and help the other readers.

• Physics Discussion Thread 1

In this post, I would like the visitors using this blog to interact with each other about anything related to Physics. I highly recommend everyone to participate and share their tips (practical, theory, ...), problems, understanding of concepts, ideas, suggestions, views (critical, ...), .... and anything about Physics. It may be about this blog, your exams, notes, studies (changes to the latest syllabus, ...) and even things that are not in your syllabus.

Note that laptops, tablets, phones, the internet, mechanical works, .... all have physics principles at their base. So, there is a lot to discuss.

The fact that this blog is visited by people from different countries around the world will greatly help you to broaden your ideas and knowledge and learn or teach new things to each other.

This is the first post for discussion, so you are free to talk about any topic related to Physics here. If you are participating, may be later we could organize discussions on specific topics of physics. If you are participating, be sure to bookmark the link and check regularly.



Comments are still being moderated. So, just write your comments and I'll try to publish them as soon as possible. I intend to publish most comments, unless they contain inappropriate contents.

I hope you'll participate in this discussion. Anyone is welcomed to start the discussions.
