Motion in a Straight Line: NEET questions with solutions

NEET tests this chapter through the kinematic equations, free fall, graph reading and the distance-versus-displacement distinction. Most marks are lost to sign-convention slips in vertical motion, forgetting to convert km/h to m/s, and applying uniform-acceleration formulas to motion whose acceleration is changing.

1. 1.A cyclist rides 3.0 km due east along a straight road in 10 min, then turns around and rides 1.0 km due west along the same road in 5 min.…Average velocity and average speedEasySingle correct
2. 2.A car moving at 54 km/h on a straight level road brakes with constant deceleration and comes to rest after travelling 45 m. What is the…Kinematic equations for uniformly accelerated motionEasySingle correct
3. 3.A student reviewing kinematics graphs for a body moving along a straight line writes four claims, labelled I to IV below. Identify which of…Position-time and velocity-time graphsEasyStatement based
4. 4.A stone is released from rest at the top of a tower and falls freely to the ground. In the last one second of its fall it covers 35 m.…Free fallMediumSingle correct
5. 5.A ball is thrown vertically upward at 15 m/s from the edge of a cliff 20 m above flat ground. On the way down it just misses the cliff edge…Vertical motion under gravityMediumSingle correct

8. 8.A car starts from rest on a straight road and accelerates uniformly at 2 m s⁻² for some time. It then brakes immediately with a uniform…Velocity-time graph and uniformly accelerated motionHardSingle correct
9. 9.A particle moves along the x-axis with position x = 6t² − t³, where x is in metres and t in seconds. What is the total distance (path…Instantaneous velocity; distance vs displacementHardSingle correct
