万有引力F=GMm/r^2r 两物体的质点距G=6.67*10的负十一次方
You can change everything with as same as gravity, like temperature, or everything theory much like gravity.
Gravity is immaterials.
The row and the column.
By the mass?
Force=G*(m1*m2/r2).
G=Newtons*(m/kg)^2;
"g" as the gravitational field at the surface of Earth which is 9.8 m/s^2;
Double force, the third law of the Newtons.
