System of Particles and Rotational Motion

Centre of mass, torque, angular momentum, moment of inertia, and rolling motion form the core of rotational mechanics. Standard-body moment of inertia numericals, conservation of angular momentum, and rolling on an incline are the usual NEET picks.

Weightage: what the paper actually did

System of Particles and Rotational Motion carried 2 questions in the NEET 2026 paper. One paper is a data point, not a destiny: NTA moves weight between chapters every cycle, which is why the weightage tables deserve care. The stable facts are the paper's shape: 180 questions, 720 marks, +4 right, −1 wrong.

Question 1 · NEET 2026

The angular speed of a flywheel is increased from 600 rpm to 1200 rpm in 10 s. The number of revolutions completed by the flywheel during this time is:
  1. A.900
  2. B.600
  3. C.150
  4. D.300
Answer and explanation

Answer: C

With uniform angular acceleration the number of revolutions equals the average angular speed times the time: 600+12002=900\frac{600+1200}{2} = 900 rpm over 1060\frac{10}{60} min = 16\frac{1}{6} min, giving 900×16=150900 \times \frac{1}{6} = 150 revolutions, option (3). Equivalently, using ω22=ω12+2αθ\omega_2^2 = \omega_1^2 + 2\alpha\theta gives θ=300π\theta = 300\pi rad, so θ/2π=150\theta/2\pi = 150.

How to practise System of Particles and Rotational Motion

Chapter by chapter, against real past-paper questions, on a screen: NEET is computer based from 2027. Read the chapter once, then attempt its PYQs until your accuracy stops climbing, and let the wrong answers tell you which lines to reread. If the chapter keeps refusing to stick, that has its own guide. There is also a free 12-question mock on the exam screen.
