Gravitational Force

#todo

Definition §

The formula for the gravitational force between two masses is:

$$F_{m_{1}on{m}_2}=-G\times \frac{m_1{m}_2}{r^2}\hat{u}$$

• $G$ = Gravitational constant = $6.67430\times 10^{-11}$
• $m,M$ = Masses of two objects (in $kg$)
• $r$ = Distance between objects (in $m$)
• $\hat{u}$ = Unit vector from $m_1$ to $m_2$
