NCERT Class 11 Physics – Gravitation
The chapter Gravitation in NCERT Class 11 Physics deals with the fundamental force that governs the motion of celestial bodies and objects on Earth. It begins with Newton’s law of universal gravitation, which explains the attractive force between two masses and its dependence on mass and distance. The concept of acceleration due to gravity and variation of gravity with altitude and depth is also discussed.
The chapter explores motion of planets and satellites, deriving orbital velocity and time periods. Concepts like escape velocity, gravitational potential energy, and gravitational field are explained with examples. Students also learn about applications such as artificial satellites, geostationary orbits, and the importance of gravitation in daily life and astrophysics.
By solving NCERT exercises and examples, students strengthen problem-solving skills and build a solid foundation for board exams, JEE, and NEET, understanding both theoretical and practical aspects of gravitation.
