How to Prepare Gravitation for JEE

A focused preparation roadmap for Gravitation in JEE Physics. Learn what to prioritise, which formulas to master, mistakes to avoid, and how to practise effectively.

Quick answer

Memorise universal gravitation, orbital velocity, escape velocity, and satellite energy relations. Quick numericals if formulas are solid.

Weightage & importance

1–2 questions; formula-heavy and scoring.

Step-by-step study plan

  1. Step 1

    Core formulas

    g, escape velocity, orbital speed sheet.

  2. Step 2

    Satellite problems

    Energy and period numericals.

  3. Step 3

    Variation of g

    Altitude and depth problems.

  4. Step 4
