Motion in a Straight Line

Here you study motion along one axis: position, displacement, velocity, acceleration, the kinematic equations, and motion graphs. NEET tests it with numericals, either direct use of the equations or reading values off position-time and velocity-time graphs.

Weightage: what the paper actually did

Motion in a Straight Line 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

When a ruler falls vertically, 5 different persons catch it with different reaction times (g=9.8g = 9.8 m s−2^{-2}). Person A has a reaction time of 0.20 s, Person B has 0.22 s, Person C has 0.18 s, Person D has 0.19 s, and Person E has 0.21 s. What is the correct order of the distance travelled by the ruler for each person?
  1. A.B > E > A > C > D
  2. B.C > D > A > B > E
  3. C.B > E > A > D > C
  4. D.C > D > A > E > B
Answer and explanation

Answer: C

The ruler falls freely, so distance s=12gt2s = \frac{1}{2}gt^2 increases monotonically with reaction time. Ranking the reaction times from largest to smallest gives B(0.22) > E(0.21) > A(0.20) > D(0.19) > C(0.18), which is the same order as the distances. Options B and D reverse the ordering (smallest first), and A swaps D and C. Why the other options are wrong: - (A) Correct start but C and D are swapped. - (B) Ascending (smallest time first) order. - (D) Ascending order with E and B swapped.

How to practise Motion in a Straight Line

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.
