Q1PhysicsUnit 2: Kinematics

A train

50 \mathrm{m}

long passes over a bridge at a constant velocity of

30 \mathrm{km} / \mathrm{h}

. If it takes 36 s to cross the bridge, the length of the bridge will be

Q2PhysicsUnit 2: Kinematics

Q Type your question-

65 k m h^{-1} .

When they reach the crossroad, one of the cars turns towards town

Q

whereas the other continues forward towards town

R

. Both continue to move with the same speed of

65 k m h^{-1}

Which of the following options is correct for given statements? (i) Both cars have the same velocities even if the car turns towards town

Q

(ii) Two bodies have same velocities if they are moving with same speed in different directions.

Q3PhysicsUnit 2: Kinematics

A boy sitting on the top most berth in the compartment of a train which is just going to stop on a railway station, drops an apple aiming at the open hand of his brother situated vertically below his hands at a distance of about

2 \mathrm{m}

The apple will fall

Q4PhysicsUnit 2: Kinematics

Assertion Distance covered by a moving body is always greater than zero. Reason Displacement of a particle can be greater than or less than or equal to zero.

Q5PhysicsUnit 2: Kinematics

Change of the position of an object with respect to the observer is called.

Q6PhysicsUnit 2: Kinematics

A train of length

100 m

is moving in a hilly region. At what speed must it approach a tunnel of length

80 m

so that a person at rest with respect to the tunnel will see that the entire train is in the tunnel at one time?

Frequently asked questions

What makes a The frame of reference, motion in a straight line, speed and velocity question "important" for JEE?

Important questions test core concepts that appear frequently across JEE Main and Advanced papers — definitions, standard formulas, and classic problem types.

Which subtopics in Kinematics are high-weightage?

Key areas include The frame of reference, motion in a straight line, speed and velocity. Prioritise these before moving to edge cases.

How many important questions should I revise?

Revise 30–50 important MCQs per unit in the last month before JEE. Focus on questions you got wrong at least once.

Can I practise only important questions on Goodmarks?

Pro users can filter by unit and subtopic to target high-yield areas. Free users can attempt sample questions on this page.
