Wiemy, że:

$G\left[\frac{N\cdot m^2}{k{g}^2}\right]$

$M\left[kg\right]$

$R\left[m\right]$

Wyprowadzamy zbiór:

$v_1=\sqrt{\frac{G\cdot M}{R}}=\sqrt{\frac{\left[\frac{N\cdot m^2}{k{g}^{\sout{2}}}\right]\cdot \sout{\left[kg\right]}}{\left[m\right]}}=\sqrt{\frac{\left[N\cdot \frac{m^2}{kg}\right]}{\left[m\right]}}=$

$=\sqrt{\frac{\left[\frac{kg\cdot m}{s^2}\right]\cdot \left[\frac{m^2}{kg}\right]}{\left[m\right]}}=\sqrt{\frac{\left[\frac{\sout{kg}\cdot \sout{m}}{s^2}\right]\cdot \left[\frac{m^2}{\sout{kg}}\right]}{\begin{array}{c}\sout{m}\end{array}}}=\sqrt{\frac{m^2}{s^2}}=\frac{m}{s}$
