Template:Mbox

Usage

This template calculates escape velocity v2 of a spherical body of the mass M and radius R:

[math]\displaystyle{ v_2=\sqrt{\frac{2 \times G \times M}{R}} }[/math].

G is the gravitational constant. The template should be used in the following way:

{{v2|M|R|PRE}},

where M is body's mass in 1021 kg, R is radius in km and PRE is the number of digits after decimal point in the result (default is 3). The result is expressed in km/s.

Example (escape velocity of Titania): M=3.526Template:Esp kg, R=788.9 km.

v2=Template:V2 km/s.
