NEET is known as the most challenging exam that one must pass to pursue a career in medicine and become a doctor. The syllabus for the NEET exam covers material from classes 11th and 12th in Physics, Chemistry, and Biology. Among these subjects, Physics is often considered the most difficult. This is because Physics requires a deep understanding of concepts and a strong grasp of mathematical equations. Many students find Physics Numerical Problems to be particularly daunting. Without the right approach to learning, Physics can be quite complicated. Continue reading this blog post to learn how to effectively solve Physics numerical problems for NEET.
For the core understanding of Physics as a subject, clear your concepts first and then solve the Numerical problems as the jest of concept application is utilized in the numerical problems.

How to solve physics numerical for NEET? | Systematic Manner
Here we discuss some approaches to solving Physics numerical for NEET 2024.
-
Read the problem carefully
The most common issue with the students is that they do not read the question carefully and mark the answer in a hurry. We recommend you read the problem patiently and try to figure out the situation. Once you know the situation, you will formulate your answer with appropriate equations. It is always advisable to read the question again and again before coming up with the context as some key information might be hidden in the texts of the problem.
For example; Starting from rest means your initial velocity is zero.
Moreover, different situations, say, to determine the final velocity and distance travelled, will require different strategies to solve. Hence, read the question carefully to be sure about the situation.
-
Don’t panic
No need to panic if you encounter a complex problem; it is simply a problem, and every problem has a solution. So, relax, take a deep breath, and then concentrate on the problem. Determine and apply your efforts to comprehend the problem’s governing principle. The more you practise, the faster you will solve the problems. As a result, set aside 1-2 hours each day to practise numerical problems in Physics.
-
Organise the information
After a careful study and understanding of the situation, list out all the information as stated in the problem, i.e. look for all the unknown variables. This is important because the actual variables remain hidden inside the texts of the problem. You may consider this problem for your better understanding:
Problem: Starting from rest, an object accelerates at the rate of 12 ms-2. What is the velocity of the object at the end of 3 seconds?
Here, the list of information includes:
Initial velocity, Vi = 0 (Starting from rest)
Rate of acceleration, a = 12 ms-2
Final velocity, Vf = ?
Time taken, t = 3 seconds
By listing all the information out of the question, you will see what is given, what is required, and what needs to be found out. This step also helps identify the formulae or equations to be used. Moreover, organizing your information will let you deal with actual physics instead of reading comprehension. You can take the help of NEET exam books for understanding the concepts better.
-
Visualise and sketch the scene
While solving a Physics problem, always try to draw a rough schematic diagram according to the situation. Drawing can transform a given problem into a representation that makes it easier to understand the hidden context better, thereby helping to solve the problem quickly.
For example; If you want to find the maximum height reached by an object that is launched at a velocity of 20 ms-1 in a direction making an angle of 25° upward with the horizontal, then the diagram representing the problem will be:
where, V0 = 20 ms-1 and θ = 25
Construction of neat diagrams and putting all the given data around it can fast-track you towards writing the correct equations and, therefore, the answers
-
Make the Units uniform throughout
Units of measurement play a very crucial role in Physics problems. Throughout the exercise, you must maintain the same units; otherwise, formulas will not work, and you will never get a correct answer.
For example; If you want to find the distance of a car that moved at 30 km per hour for 15 minutes, you will need to convert the units to get a correct answer. This means you have to either convert
- 30 kilometres per hour to kilometres per minute, 30 km in 60 minutes
Or,
- 15 minutes to units of hours, e. 0.25 hours.
Additionally, always check the demand of the units in answer. You are getting a response in m/s, but the correct option might be available in Km/min. Neglecting this may lead to the selection of the wrong option.
-
Consider your formulas and solve your physics problems
One of the essential tools to solve physics problems is the formulas. You need to understand the derivation of the formula and memorize the application part of formulas. More and more practice will help you keep them in your mind. Let’s consider a simple formula to find out its real meaning,
F = ma
This formula tells you three things, for a given mass;
- The more the force, the more the acceleration, which means the harder you push an object, the more it will be accelerated.
- The more the mass, the more the force, which means if you want to push two objects with masses of 10 kg and 15 kg respectively, you need to put more force on the second object as it is heavier.
- The more the mass, the lesser the acceleration, which means if you apply some force on both the above objects, the heavier one will accelerate slower than the less heavy one.
Hence, there is a lot of information stored in any formula. If you want to understand Physics and solve problems based on it, you need to understand the formulas first, which will help you memorize them quickly.
Once you have figured out the formulas, it’s time to solve the problem. While solving, you have to focus on your target, i.e., the variable marked with a question mark. Keep the target in mind and solve the equations.
-
Practice more to master the physics problems
As far as understanding is concerned, you need to check the abovementioned points. Doing anything fast is a skill, and practice more to perfect any skill. The more problems you can solve, the better. You will start to see patterns in approaching certain types of physics problems.
After a routine practice, do some exam-oriented questions practice. For this, you can use NEET Champion Physics and NCERT at your Fingertips – Physics. These are the best books for NEET Physics preparation. Also, you must refer to previous years papers for solving and practising as many problems in Physics until you become a master in solving them.
