#F = ma#

Explanation:

If you are speaking of objects like satellites, etc. then their mass is much less than that of the Earth. A good approximation is Newton's first law of motion:

#"Force" = "Mass" xx "Acceleration"#

often written:

#F = ma#

The gravitational force is the same between the Earth and the object - only the mass differs. So the acceleration is inversely proportional to the mass.
