Motion in a Straight Line — Previous-Year Questions
6 curated PYQs across 6 topics, drawn from JEE Mains, JEE Advanced, NEET UG, and CUET papers. Every question has a worked-out explanation.
Position–Time Graph
See how x(t) = x₀ + v₀t + ½at² unfolds — slope = velocity, curvature = acceleration.
Q1. An x-t graph is a parabola with vertex at origin opening downward. Motion is:
JEE 2020Velocity–Time Graph
Linear v(t) from constant acceleration — area under curve = displacement.
Q1. A v-t graph is a straight line with positive slope. The motion is:
JEE 2019Q1. An object has a = 2 m/s² for 3s, then a = −1 for 2s. Net Δv is:
JEE 2021Uniform Acceleration
Ball with initial velocity and constant acceleration — live v and a arrows.
Q1. A car accelerates from rest at 2 m/s² for 5 s. Distance covered:
JEE 2018Free Fall
Drop a ball from any height — gravity arrow, v arrow, fall time, impact velocity.
Q1. A ball dropped from 45 m. Time to reach ground (g=10):
JEE 2020Relative Velocity (1D)
Switch reference frames — ground, A, B — and see velocities transform.
Q1. Two trains 60 and 40 m/s in opposite directions. Relative speed:
