NEET 2026 Physics 🔥 | 20 Most Repeated Questions | 80+ Marks Strategy 🚀
PW NEET English
Overview
This video focuses on a strategy for NEET 2026 Physics, specifically by analyzing 20 highly repeated previous year questions (PYQs). The presenter emphasizes identifying patterns in question types and topics frequently tested by the NTA. Key areas covered include units and dimensions, error analysis, vernier calipers, kinematics (differentiation and integration), collisions, vertical circular motion, and electric dipoles. The strategy involves mastering the 'bare minimum' concepts, then progressing to more challenging problems, potentially by referencing JEE Mains PYQs. The video aims to build confidence by highlighting common question formats and providing a structured approach to physics preparation, even in the final days before the exam.

Chapters
- The video presents 20 repeated PYQs for NEET Physics 2026 to guide preparation.
- A key strategy is recognizing patterns in chapters where NTA frequently tests specific topics (A, B, or C).
- Focus on revising PYQs similar to the ones presented to cover high-probability areas.
- The goal is to achieve 80+ marks by focusing on these repeated question types.
Understanding the strategic importance of repeated question types helps learners prioritize their study efforts and focus on high-yield topics for the NEET exam.
The presenter mentions that certain chapters have a predictable pattern where NTA is almost certain to ask questions from specific topics.
- Units and Dimensions, along with Errors and Instruments, are crucial topics expected to yield three questions.
- Vernier calipers problems often involve finding the least count (vernier constant) using the formula: 1 MSD - 1 VSD.
- Percentage error calculations typically involve adding errors and multiplying by the power of the respective quantity.
- For complex problems, using dimensional analysis or matching options can save significant time.
Mastering these fundamental concepts is essential as they form the 'bare minimum' and are frequently tested, with errors often being a direct application of formulas.
A typical vernier caliper problem where 'n+1' vernier scale divisions coincide with 'n' main scale divisions, requiring calculation of the vernier constant.
- Questions involving time (t) as a function of position (x) often require differentiating with respect to x to find dt/dx, then taking the reciprocal to get velocity (dx/dt).
- Acceleration can be found using the formula a = v dv/dx, which is useful when velocity is expressed as a function of x.
- It's crucial to identify and revise formulas or concepts where you face difficulty, such as the relationship between t, x, v, and a.
- JEE Mains PYQs can be a valuable resource for increasing the difficulty level of practice problems.
This section highlights how calculus concepts are applied in kinematics, emphasizing techniques to solve problems efficiently, especially when direct differentiation with respect to time is complex.
Given t = x^2 + x, find acceleration. The solution involves finding dt/dx = 2x + 1, then v = dx/dt = 1/(2x+1), and finally a = v dv/dx = -2/(2x+1)^3.
- Collisions, including elastic and inelastic types, are important topics.
- Conservation of linear momentum is valid for all types of collisions where the net external force is zero.
- Conservation of mechanical energy is only valid for elastic collisions.
- In a completely inelastic collision, objects stick together and move with a common velocity, allowing for momentum conservation calculations.
Understanding conservation laws is fundamental to solving problems involving interactions between objects, particularly in collisions and explosions.
Two bodies of equal mass undergo a completely inelastic collision, with one initially at rest. The resulting common velocity is half the initial velocity of the moving body (v = v1/2).
- Vertical circular motion is a critical topic, and understanding concepts like the string becoming slack is key.
- When a string becomes slack, it implies the tension is zero, which helps in calculating the velocity at that point (v^2 = rg sin theta).
- Conservation of mechanical energy is a powerful tool that can be applied even if specific formulas are forgotten.
- The relationship between initial velocity (v0), velocity at a point (v), and height gained can be derived using energy conservation.
This topic integrates concepts from Newton's laws, circular motion, and energy conservation, demonstrating how these principles work together to solve complex problems.
A bob suspended by a string is given a horizontal velocity. Using conservation of mechanical energy, the ratio of velocities at different points can be determined, especially when the string becomes slack.
- Electric dipoles are a frequently tested topic in NEET, requiring knowledge of electric field, potential, torque, and potential energy.
- Potential energy of a dipole in an electric field is given by U = -PE cos theta.
- The work done to rotate a dipole is equal to the change in potential energy.
- When dissipative forces like friction are present, the work-energy theorem (Work = Change in Kinetic Energy) should be applied instead of conservation of mechanical energy.
Understanding electric dipoles and the conditions for applying conservation laws versus the work-energy theorem is crucial for solving problems in electromagnetism and mechanics.
Calculating the potential energy of an electric dipole aligned with an electric field and then rotated by 60 degrees, resulting in a potential energy change of PE/2.
- Physics problems can range from easy to super difficult; focus on mastering the 85% that are not 'super difficult'.
- For problems involving multiple blocks, first find the common acceleration, then analyze individual blocks.
- When faced with complex problems, stay calm, identify knowns and unknowns, and look for familiar patterns or formulas.
- Referencing JEE Mains questions can provide exposure to a wider range of problem types and difficulty levels.
This section provides practical advice on managing exam anxiety and approaching problems of varying difficulty, emphasizing a strategic mindset over rote memorization.
To find the force exerted by block A on block B, first calculate the common acceleration of the system (Total Force / Total Mass), then analyze block B's motion.
