Gravitation

This topic explains Kepler’s laws associated with the gravitational force. Law of the period, orbit and area are well explained here with the help of elaborate illustrations and different measurements that confirm Kepler’s law of motion.

This topic describes the universal law of gravitation. Mathematical representation of Newton’s law of gravitation and results of the simple law are also explained here in detail with diagrams.

This topic discusses the expression of acceleration due to gravity in terms of gravitational constant. It highlights the variation in the value of acceleration due to gravity. We will also study the effect of altitude, depth and latitude here.

This topic makes us understand the intensity of gravitational field, gravitational potential and potential energy. It also covers the derivation of formulas of each and explains their application for solving questions.

This topic helps us in understanding that we can throw an object with such high initial speeds that it does not fall back to the earth. The mathematical proof of escape speed is also explained.

This topic discusses the orbital speed and period of revolution of satellites. It provides a detailed description of geostationary satellites along with their height from the Earth's surface. It also covers the value of the orbital speed of the same.

This topic describes the phenomenon of weightlessness. It also explains the conditions and how acceleration due to gravity and gravitational force plays a role in the weightlessness of a body.

In this topic, we will acquire knowledge about geostationary and polar satellites. The function and structure of geo satellite and polar satellites is also discussed here along with the journey of India into space.
