Physics
Gravitation for JEE Main & Advanced — orbits, escape velocity, and potential
How gravitation bridges particle mechanics and modern astrophysics questions on both papers.
On JEE Main
Main tests Kepler's laws, orbital velocity and escape velocity formulas, variation of g with altitude and depth, and gravitational potential energy in single-correct MCQ format. Satellite time period calculations are a staple question.
On JEE Advanced
Advanced uses multi-correct and integer formats with two-body orbital mechanics, gravitational field inside non-uniform shells, and energy conservation for transfer orbits. Integer-type questions require comparing orbital radii or periods across two different central bodies.
