• Newton’s law of universal gravitation states that everybody in the universe attracts every other body with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
• The Earth attracts a body with a force equal to its weight.
• It is assumed that a gravitational field exists all around the Earth due to the gravitational force of attraction of the Earth.
• In the gravitational field of the Earth, the gravitational force per unit mass is called the gravitational field -1 strength of the Earth. It is 10 N kg near the surface of the Earth.
• Acceleration g = G ME/R2
• Mass Of Earth Me = R2g/G
• g at an altitude he = G M/(R+H)2
• An object that revolves around a planet is called a satellite.
• The moon revolves around the Earth so moon is a natural satellite of the Earth.
• Scientists have sent many objects into space. Some of these objects revolve around the Earth. These are called artificial satellites.
