Motion in a Plane — Class 11 CBSE Physics revision notes
A 5-page visual revision sheet for Motion in a Plane, 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 Motion in a Plane sheet covers
- Scalar vs vector
- Scalar
- Vector
- Special vectors
- Adding vectors geometrically
- Magnitude and direction of the resultant
- resultant magnitude
- direction, from A
- same direction, θ=0°
- opposite, θ=180°
- perpendicular, θ=90°
- subtraction
- Resolving into components
- Projectile motion, the big idea
- Time, height, range

- Range extremes
- Maximum range
- Same range twice
- Velocity at any instant, and the path
- horizontal component, fixed

- 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 Motion in a Plane 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.
