Engineering entrance prep – JEE Main and Advanced physics series, chapter notes, solved examples and revision cards.
Kepler's three laws — ellipse orbits, equal areas, T² ∝ r³ — with the 15-second ratio method that turns them into guaranteed marks, and how they discovered Neptune and 5,800+ exoplanets.
Orbital velocity vₒ = √(GM/r) = √(gR) from centripetal-force balance, the r = R+h trap, and why higher satellites move slower — with the √2 link to escape velocity.
Escape velocity vₑ = √(2GM/R) = √(2gR) derived from energy conservation, with the Moon worked numerical, the three traps that cost marks, and why the Moon has no atmosphere.
GATE — the Graduate Aptitude Test in Engineering — exam-ready notes.
