Are physics chapters interrelated with each other if I am preparing for neet?

Physics is a subject which requires imagination. It depends on your imagination power.

• First of all, I'd suggest you to learn basic mathematics as it is needed in each and every section of physics.
• Don't try to memorise the formulas, just try to derive them once. So even if you don't remember the formula, you'll be able to derive it on the spot. I had applied this method and seriously it helped me a lot because I didn't have to cram up such dangerous formulas.
• Practice Physics daily. This is the need for the subject if you have no idea about this subject ( like I didn't even know the syllabus of physics for NEET.) Don't try to solve each and every MCQ books, as 90% of the questions are almost same in all the basic books. Just prefer one book and make sure to solve its each and every question. If you have finished one book then go through the other but remember the second book should be of higher level.
• Make your theory strong. I repeat again make your theory part strong. Without theory you'd never be able to get the practical knowledge and Physics is all about practical knowledge like how much you can imagine on the given topic. Just make sure to read theory. Either read it out from any standard book like H.C. Verma. or go through such sources which are giving you the correct information. As lot's of coaching classes and teachers over there don't have good knowledge of the subject. They just deliver according to their level, so go through the wonderful notes as it makes your theory part strong and indirectly it'll increase your overall performance.
• Time management- Well that's the most important part of this answer. You have to maintain speed as well as accuracy. You have to solve each question in one minute. But this speed doesn't come very easily. You have to work hard for it. In my opinion, you should focus on the accuracy first and then hunt for the speed. Because once you know how to solve questions correctly, you'll gain your speed automatically. But again Practice Practice Practice. That's the only thing needed here. Just take a watch and set an alarm and look how many questions you can attempt in 60 mins. This will surely help you.

Best of luck for your preparation.

they are not clearly interrelated to each other. but in solving numerical and in understanding of some topics you need some basic knowledge that can make easy to understand. means if you are facing any problem to understand then you should need to check related topic of the last chapter. but it is not completely interrelated.
