Indian National Physics Olympiad
INPhO stands for The Indian National Physics Olympiad, which is held every year in June and July by the Indian Association Of Physics Teachers (IAPT). It is designed specifically for secondary school students who want to improve their understanding of Physics on a global scale. The success and pleasant experience of the International Mathematics Olympiads in 1959 led to Prof. Czeslaw Scilowski's introduction of Physics in Warsaw (Poland) in 1967. The IPhO is a competitive examination that acts as a standard for pre-university students studying Physics, encouraging good ties among them from all around the world. The primary goal of the INPhO test is to raise the standard of Physics education among students in the country and prepare them for INPhO.
The Indian National Physics Olympiad is an international level competition in the discipline of Physics aimed at secondary school students (grades 11 and 12) to foster worldwide links in school education in Physics. The INPhO Exam is the second level of India's five-stage Olympiad programme in Physics. It is generally hosted on the last Sunday of January by the Homi Bhabha Center for Science Education (HBCSE) (or on the first Sunday of February). In the end, qualifying for INPhO leads to selection for the International Physics Olympiad.

Syllabus for INPhO
Mechanics: Newton's laws and inertial systems are the foundations of the kinematics of a point mass. Closed and open systems, momentum and energy, power work, and so forth. Energy conservation, impulse, and linear momentum conservation Elastic forces, gravitational law, frictional forces, potential energy, work in a gravitational field, centripetal acceleration, and Kepler's laws are all examples of elastic forces.
Rigid body mechanics: statics, torque, and the center of mass Translation, angular velocity, rotation, angular acceleration, and angular momentum conservation are all terms used to describe rigid body motion. This course covers subjects such as external and internal forces, equation of motion of a rigid body around a fixed axis, kinetic energy of a rotating body, moment of inertia, and accelerated reference systems and inertial forces.
There will be no specific questions in hydromechanics, but students should be familiar with the basic principles of continuity, buoyancy, and pressure.
Internal energy, thermodynamics' first and second laws, work and heat, and molecular thermodynamics Avogadro's number, absolute temperature, perfect gas model, pressure and molecular kinetic energy, perfect gas equation of state Work done by an expanding gas restricted to isothermal and adiabatic processes includes the Carnot cycle, reversible and irreversible processes, thermodynamic efficiency, entropy (statistical approach), and Boltzmann factor.

A qualitative assessment of the performance and degree of preparation.
Candidates studying for the INPhO test can study Vedantu's INPhO Olympiad previous year question paper. If the INPhO Olympiad previous year question papers 2024-25 are consulted, the preparation for the INPhO Exam 2024-25 is half done. These question papers play an essential part in the INPhO Exam 2024-25 preparation.
3. How preparation plays a major role for the INPhO students?
Students who plan to take the INPhO test should prepare throughout the year. When it comes to students intending to take the INPhO test, preparation is crucial. Preparation is crucial to the result. Vedantu has published the INPhO Olympiad previous year question paper 2024-25 in PDF format to assist students. Solving these problems offers pupils an understanding of the question paper design, marking scheme, and critical themes that demand extra focus, among other things.
4. What are the stages of INPhO?
The stages of INPhO are:
Stage 1: National Standard Examination in Physics (NSEP)- The full title of NSEP is National Standard Examination in Physics.
Stage 2: INPhO (Indian National Physics Olympiad)- The full name of INPhO is Indian National Physics Olympiad.
Stage 3: Orientation cum Selection Camp (OCSC)- In Physics, the full term of OCSC is Orientation cum Selection Camp.
Stage 4: PDT stands for Pre-departure Training Camp for IPhO in its complete form.
Stage 5: IPhO (International Physics Olympiad) - IPhO stands for Participation in International Physics Olympiad.
5. What will be the cut off for indian national physics olympiad result?
The INPho 2024-25 cut off depends upon the changes of marks after reassessment. By executing web scrapers we get to know the marks of every candidate who wrote INPHO.
6. My friend scored 57.5 on 114.5 in INPho 2023. Is this score good or bad? Does she stand a chance for INPho?
Given the academic year 2023, there are scores of more students given the exam, and considering that there must thus be some increment in the INPho cut off because of it, the cutoff shall be around 60 or 62 in 120 marks. However, this is not certain because the whole concept of INPho cut off and selection is based on relative performance; this was presuming that the cutoff remains the same percentage of marks on the whole.
7. What will be the best preparation for the physics olympiad?
Those already preparing for JEE need not do much preparation for these Olympiads separately since they don't have much content outside the general JEE syllabus (unlike INMO for instance, which is a different game altogether). Augmenting your problem-solving skills with an irodov/krotov book is a good idea. Also, as with all exams, check thoroughly through the past year papers which are available on the official website. Practicing steadily through INPho previous year papers will make even mundane calculus optimization come off. In addition, one helpful trick that might come in handy is vector calculus. Ample of physics problems can be pretty mechanically reduced to mathematical equations and then brute-forced with almost 0 physical insights.
8. How do I study for NSEP and INPHO from the beginning? What study material do I refer to?
The first thing you need to do is to be thorough with a basic JEE book (the best example we can provide is HC VERMA’s CONCEPTS OF PHYSICS). If you have set a strong base in solving these problems, half the job is done as it gives you unimaginably excellent concept clarity. Following this, you can begin using these books to crack the INPHO exam…
