How to solve Physics Problems in NEET 2020

By Neetu Pathak|Updated : June 1st, 2019

In this article, we are sharing the most important things required while solving any numerical based problem.

As we know, Physics has always been considered to be the most complicated subject. Physics, especially for NEET requires a very keen conceptual approach along with basic theoretical knowledge to the problems. Moreover, there are many derivations and Formulas which requires a good level of Mathematical approach to get to the final result or answers.

In order to crack the questions and scoring good marks in physics, a proper strategy and planning are required. In this article, we emphasize how the student should ride the ladder from the basic Physics to the Complex topics which will be useful from the examinations point of view!!

1. Stay Calm, No need to Panic

I know it would be easy in words but it's tough to follow. Usually, when we face a question, our mind automatically creates a certain framework that whether it is a tough question or an easy one. But hold on, the moment you put a tag to a question that it is a difficult one, then I'm quite sure you would not be able to solve it, even though it won't be that difficult. This state of mind does more harm than help you. It acts as a trigger to rush down negativity in your entire blood!!

That’s the time where you need to act smart and stay calm. Take a deep breath and then just go on!!

Try to apply the basic approach to that particular problem as there are many questions which are easy but asked in a  tricky manner due to which students get confused. If you know all the important formula and rest basic tricks then, surely you will get the answer. The main strategy here is that you just have to stay calm and be composed all the time while doing numerical, recall the concept and formulas, apply them confidently and gradually will lead to the perfect answer!!

2. Identify the topic of the problem.

What exactly is the question saying and what they want in the answer is also an important aspect in the section of physics. Whether the question is about wave optics or Ray optics? Figure out the context first. There is no need to understand all the textual part in the question if it’s a simple numerical. Read the entire problem with focusing on the main points and parallel you should start the question with a very basic approach.

3. Read the Question Properly

By identifying the problem, you now know what exactly the question is all about. Many times, the students read the question once and start directly putting the formula due to which they miss the important content that could be a major aspect of that particular problem. The students are advised to read the question more than one time as it will be beneficial to reach the exact correct answer.

There are many problems in which the statement like “Car is starting from the rest” The initial time will be zero in that case and the initial velocity will also be zero!

4. Organize the Information

Theoretically, a  problem contains a lot of words which are sometimes irrelevant to the questions but also in many cases you get to know the effect of that word in the problem later.  Just For example, if the question says “ A bus that starts moving from rest and takes 7 min to reach a speed of 25 km/hr, then you should surely note down the basic variable quantities like:

  • Initial velocity(u) = 0 km/hr
  • Time(final) = 7 min
  • Final Velocity(v) = 25 km/hr
  • Acceleration (a) = ?

This problem does not require any extra approach. All you need is to focus on the important points and make a linear equation using Laws of Motion which will be easy for you to solve.

5. Make a proper figure for the Problem

Preparing a proper figure for the question in Physics reduces half of the difficulty of any problem. All you need is to make a rough layout and keep drawing as the question says. If the question is from Force, Mechanics, Gravitation then you need to just resolve the force acting in its Sine and Cosine resolves.

You don't need to be in good in drawing but should draw a neat diagram and keep on solving as the question says.

6. Units and Dimension

The units and dimensions are the bases of any Answer or the Variable. The questions in NEET and all Other Exams consist of problems where the entire information is given in the different units and the answer is asked in some other specific units.

The easiest way is to learn conversions. Also, always figure out the units of the questions. Sometimes, in question the units are given in the MKS system and answer is asked in SI. So make sure you are able to figure this out.

  • If we continue our last example where time was 7 min then we can convert it in Hour by dividing it by 60 min.

7. Formula Should be right!

If you are in confusion, write down all the related formulas in front of you and then by using variables given in questions, you can easily deduce which particular formula to be used. I would suggest you write down the formulas in the blank area rather than on the question as it's prohibited. 

8. Solve

Using the above formulas, solve the entire questions. If there are more than one equations then you should solve it simultaneously. Also, try not to do excessive calculations and making a normal solution complex.

9. Match your Answer

After doing the solution, match your final result to the answer given in the option. Many times there are many answers approximately closer to the resulting value of the final answer so in such case we should choose the nearest value to that particular result.

10. Practice as much as you can

For scoring good in the entire section of Physics you need to practice as many questions you can. We provide a variety of questions, Quizzes and Speed Test on Physics for which you can click on the tab given below:-
