Do different masses affect the value of g, the acceleration due to gravity?

Question

Do different masses affect the value of g, the acceleration due to gravity?

Answer 1

In a sense Yes! Little g (9.8m/s2) is what it is here on Earth because of the mass of the Earth. On a different planet g would be different because the mass of that planet would be different (probably).

For example on our Moon, little g is about 1/6 of Earth's g because the moon's mass is a lot less than Earth's.

Answer 2

havent you seen the famous experiment where a feather and a hammer are dropped in a vacuum from the same height at the same time, and they both hit the ground at the same time?

Answer 3

Well it all depends on how one looks upon it.

Mathematically

F= G M1M2/R^2

and

F= gM2

in that case  g is strongly related to the value of mass M1 like in

g= G M1/R^2.

So as long as M1 (mass of say Earth) remains the same and the mean distance R also the same we have g very much pinned down.

Does that answer your question?

Answer 4

No, the force of 9.8 m/s^2 never changes regardless of mass.

The change in mass will affect things like momentum.
