The above chapter-wise name and number of questions with the weightage will help you in planning your studies.
Preparation tips
To clear this exam, you all should cover the entire syllabus and plan smartly. Let us check a few important tips for preparation:
- Exam syllabus and marking scheme: The first and foremost step of any exam is to be aware of the exam syllabus and plan accordingly. Also, make sure to be aware of the marking scheme.
- Clarity of concepts: You should have clarity about all important concepts. If there is any doubt, then make sure to clear them through various means.
- Understanding formulas: Physics is highly based on formulas. Make sure to know and apply all the formulas. You should make sure to revise all the formulas at a regular interval.
- Best Resources: While preparing for Work, Energy and Power MCQs, make sure to use the best resources to get crisp, clear knowledge of all the concepts and get good practice.
- Practice past papers and mock papers: You should even practise mock papers and past papers to get the exam feel to analyse what topics you have scored well and what topics you have not done well. You can rework the topics which you’ve performed poorly. You will also understand time allocation by practising past papers and the level of difficulty and type of questions asked.
- Prepare your notes: The best way to study is to make your notes. You can make notes for formulas, theorems and principles. This will provide you to revise concepts clearer and aid as a last-minute revision. Also, handwritten notes are proven to improve brain efficiency.
- Analysing the important topics: Analyse which topics are most important and which are less. Accordingly, focus on the most important topics and then on less important.
- Video-based content: You can also refer to the content-based video to clear your doubts and better understand the concepts.
- Multiple revisions: You should do multiple revisions before the final exam to better hang the topics and get more confident in your concepts.
- Stay calm and be confident: One of the best ways to be calm is through meditation. If you are calm, you can concentrate better on your studies and being confident will be a brownie point for your exam.
After knowing the above tips, you can plan your studies well and ace the exams.

Work, Power and Energy
In a glimpse, Work is said to be done when a force is applied to it, and there is motion or displacement in the direction of the force.
W = F * s
Where,
W= Work
F= Force
s= Displacement
The SI unit of Work is Joule (J). It is a scalar quantity.
Energy is the capacity or ability to do Work. It can never be created or destroyed but only changes one form to another. It does not have magnitude and direction. It is a scalar quantity.
In terms of Work and Energy, power is the rate of doing Work.
P= W / t
Where,
P= Power
W= Work
t= time taken
The SI unit of power is Joules per second which is Watt. It is a scalar quantity.
Sub-topics of Work, energy and power for NEET
Let us better understand the sub-topics to be covered in Work, energy and power to get a clear idea of the topics to be studied.
By studying these topics, you can attempt MCQs on work power and energy to get full marks that will help in increasing your overall score.
Conclusion
After reading the whole article, you can plan your studies well to clear the NEET Physics exam.
