The satellites orbital speed does not depend on it’s mass for the same reason the acceleration due to gravity does not depend on the mass of the falling object. That is the relationship dictated by the law of gravity.
Q. Does the mass of the satellite have any impact on its orbit?
The mass of the satellite definitely affects where it stays in the orbit (leo, meo or geo). Gravitational force between two objects is directly proportional to the product of their masses and indirectly proportional to the square of the distance between them.

Q. Does the speed of a satellite depend on its mass?
The speed of a satellite in circular orbit around a planet does not depend on the mass of the satellite.
Q. What happens to time period of satellite if mass is doubled?
In above formula the mass of the satellite (m) is not used. Hence , on doubling the mass of the satellite, its time period will remain unchanged.
Q. Is value of G actually constant?
In SI units, its value is approximately 6.674×10−11 m3⋅kg−1⋅s−2. The modern notation of Newton’s law involving G was introduced in the 1890s by C. V. Boys….Gravitational constant.
| Values of G | Units |
|---|---|
| 6.67430(15)×10−11 | m3⋅kg–1⋅s–2 |
| 4.30091(25)×10−3 | pc⋅M⊙–1⋅(km/s)2 |
Q. What are the three differences between G and G?

| Gravitational constant (G) | Acceleration due to gravity (g) |
|---|---|
| It is defined as the force of attraction between two objects of unit mass each separated by unit distance. | It is defined as the acceleration of an object freely falling under the action of force of gravity. |
Q. What is acceleration due to gravity explain formula of relation between G and G?
The acceleration due to gravity is the acceleration experienced by an object during free fall when in vacuum due to the gravitational force of the Earth. The standard value of g is 9.8 m/s² on the surface of the earth. We know that gravitational force F = GMm/ (r+h)²
