Gravitation — Class 11 CBSE Physics revision notes
A 3-page visual revision sheet for Gravitation, written for Class 11 CBSE Physics. Formulas, diagrams and the traps that cost marks, laid out to be read the night before rather than the term before. Free, and it opens inside CapCompass.
What this Gravitation sheet covers
- The universal law of gravitation
- force between two point masses
- universal gravitational constant
- always attractive, along the line joining the masses
- What the law actually says
- Kepler's laws
- Acceleration due to gravity
- at the surface
- at height h above the surface, h ll R
- at depth d below the surface
- Why g isn't quite constant everywhere
- g at a height above the surface
- Gravitational potential energy
- of a mass m at distance r from mass M
- at infinite separation, by convention
- near the surface, small height h
- Escape speed vs orbital speed
- Escape speed
- Orbital speed
- Energy of an orbiting satellite
- Types of satellites
- Time period of a satellite
- circular orbit, radius r
- in terms of g and R, for a low orbit r ≈ R
- Symbols
- Traps that cost marks
- Tricks that save time
How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans Physics chapter by chapter against your real exam dates and free hours, and when the plan reaches Gravitation the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
