UP Board Class 11 Physics – Gravitation
The chapter “Gravitation” explains one of the most important forces in nature — the force that binds the universe together. Students learn about Newton’s law of universal gravitation, which states that every object in the universe attracts every other object with a force depending on their masses and the distance between them.
This chapter covers key concepts such as gravitational constant (G), acceleration due to gravity (g), and how these quantities vary with altitude, depth, and latitude. Students also explore the ideas of mass and weight, gravitational potential, and gravitational potential energy. The chapter explains how planets revolve in stable orbits and introduces Kepler’s laws of planetary motion, which describe the motion of celestial bodies.
Real-life applications like satellite motion, escape velocity, and free fall make the chapter engaging and practical. By understanding gravitation, students develop a strong foundation for topics in astrophysics, orbital mechanics, and advanced classical physics.
