Laws of Motion — Class 11 CBSE Physics revision notes
A 8-page visual revision sheet for Laws of Motion, 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.

Laws of Motion in one look
why things stay put, why they move, and why every push pushes back
Newton's first law, inertia
- a body keeps its state unless a net external force acts
- that stubbornness is inertia: mass is its measure
- Galileo: the ball reaches the same height, farther on a gentler slope
- bus starts, you lurch back; it brakes, you lurch forward
- no net force means no change in motion, not no motion
Newton's second law, impulse
- net force and rate of change of momentum
F = dp/dt - for constant mass
F = ma - momentum, defined
p = mv - impulse, a large force for a short time
J = FΔ t = Δ p

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 Laws of Motion 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.
