Gravity is a force between two object and depend on their mass. and gravity force between two body is shown by Einstein General Relativity Equation.
if mass of bodies are low (lower than sun mass), we can use First Order of approximation of Einstein General Relativity Equation: "Newton gravity equation"
Fg= G * m1 * m2 / (r^2)
Fg is Gravity Force
G is a constant
M1 and M2 are mass of two bodies
r is distance between two bodies.
so, for calculate the gravity between earth and another body, u must know the mass and distance.
earth mass is: 5.9736Ã10^24 kg

...I kinda forgot... But there's a constant number for the Earth's gravity in physics... I guess it's 9... Oh,yeah... 9.8 , or something like that,so it was rounded off to 10...

The earths acceleration due to gravity is relatively constant at 9.8 m/s² at sea level.

Interesting...
Earth's gravity is best decribed as 1g.
The moon's gravity is said to be 1/6g.

Try writing a complete sentence. A verb would be useful.
