Deriving gravitational acceleration from the formula for the force of gravity [closed]
I'm trying to derive this $g = 9.8 m/s^2$ from this
$$F = G\frac{m_E\cdot m_2}{(r)^2}$$
So I did:
$$g = G \frac{(5.972\cdot 10^{24}kg)}{(6.371km)^2} \Leftrightarrow \\
g = 6.67\cdot10^{-11}Nm^2/kg^...

Gravity change as a function of time only [duplicate]
Is it possible to find how gravity changes with time? That is, height is not part of the equation.
For example, $g$ can be expressed as a function of height that does not involve time with this ...
