Mass of the moon = 7.4 x 10^22 kg radius of the moon = 1.74 x 10^6 m G = 6.67 x 10^(-11) N-m^2/kg^2. Newton observed that an object, an apple, when released near the earth surface is accelerated towards the earth. So, here is the Class 11 Physics Gravitation Notes for IIT JEE, NEET & Board Exam Preparation. The work done in carrying a mass ‘m’ from infinity to a point at distance r is called gravitational potential energy. • Intensity of Gravitational Field The speed of planet varies in such a way that the radius, vector drawn from the sun to planet sweeps out equal areas in equal times. Mass and Mean density of Earth is given in the following manner. The satellite having the same time period of revolution as that of the earth is called geostationary satellite.
