Gravitation — NEET/JEE Questions, Notes & Weightage
Class 11 Mechanics II NEET weightage: High 1,087 questions
Covers Newton's law of gravitation, gravitational potential energy, escape velocity, satellite motion, and Kepler's laws. Orbital-velocity and escape-velocity numericals, along with variation of g with height/depth, are tested almost every year.

Frequently asked questions
What numerical is asked most from this chapter?
Calculating orbital velocity, time period, or escape velocity for a satellite — and how g varies with height or depth below the surface — are the most frequently repeated formats.
Are Kepler's laws tested numerically or just conceptually?
Mostly conceptually, though Kepler's third law (T² ∝ r³) occasionally appears in comparative numericals between two orbits.
