Frequently asked questions

What makes a Laws of Motion 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 Laws of Motion are high-weightage?

Key areas include Force and inertia, Newton's first law of motion, momentum, Newton's second Law of motion, impulse, Newton's third Law of motion, Law of conservation of linear momentum and its applications, equilibrium of concurrent forces, Static and Kinetic friction, laws of friction, rolling friction, Dynamics of uniform circular motion, centripetal force and its applications: vehicle on a level circular road, vehicle on a banked road. 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?
