Question

Does the speed of a satellite around the earth depend on its mass? Its distance from the earth? The mass of the earth? Justify your answer.

Answer 1

$F=ma\to G\frac{Mm}{r^2}=m\frac{v^2}{r}\to v=\sqrt{G\frac{M}{r}}$ So,

the speed of a satellite around the Earth depend on its distance from the Earth and the mass of the Earth.
