Gravitation
Apples fall and the Moon circles Earth under one law. Chapter 7, Gravitation, of the NCERT Physics textbook for Class 11 traces that unification. You will study Kepler's laws of planetary motion, the universal law of gravitation, and acceleration due to gravity with its variation by altitude, depth and rotation. Gravitational potential energy and potential lead to escape velocity and orbital velocity, and geostationary and polar satellites illustrate the theory, connecting classroom mechanics with space flight.
