Master the foundations of statics, kinematics, Newtonian dynamics, work-energy principles, momentum, rotational motion, gravitation, and fluid mechanics with rigorous step-by-step MathJax derivations and advanced practice problems.
Module 3: Kinematics · Practice · JEE Main level · 20 questions · long answer JEE Main Practice: Kinematics Numerical Twenty multi-part problems. Full working expected — these are written to be solved on paper, not recognised. Show the working, not just the answer. Several of these have a part that is quicker by structure … Read more

A formula on the page invites scrutiny. A drawing beside it is believed. That asymmetry is the reason this set exists.
An average compresses a history into a single number. What survives the compression depends entirely on what you divided by.
The height is the position. The slope is the velocity. Reading one when the question asked for the other is the commonest error in this topic.
Never ask what the pulley formula is. Ask which portions of the string change length when this body moves.
Calculate only what is required. Do not calculate simply because the mathematics allows you to.
Acceleration has two jobs: changing how fast you are going, and changing where you are going. One dimension only ever showed you the first.
A constraint does not tell a particle how to move. It tells the particle which motions are allowed — and every pulley formula follows from differentiating one geometric statement.
