  • Gravitation | Equation of Motion of freely falling Bodies | Class 9

    Equation of Motion of freely falling Bodies When the bodies are falling under influence of gravity, they experience acceleration g i.e. 9.8 . However, when these are going up against gravity they move with retardation of 9.8 . All the gravitation of motion already read by us are valid for freely falling body with the…

  • Gravitation | Acceleration Due to Gravity | Class 9

    Importance of the Universal Law of Gravitation The universal law of gravitation successfully explained several phenomena which were believed to be unconnected. 1. It is the gravitational force between the sun and the earth which keeps the earth is uniform circular motion around the sun. 2. The gravitational force between the earth and the moon…
