=== Usage ===<br />
This template calculates escape velocity ''v2'' of a spherical body of the mass M and radius R:<br />
<br />
<math>v_2=\sqrt{\frac{2 \times G \times M}{R}}</math>.<br />
<br />
G is the [[gravitational constant]]. The template should be used in the following way:<br />
<br />
<nowiki>{{v2|M|R|PRE}}</nowiki>,<br />
<br />
where M is body's mass in 10<sup>21</sup>&nbsp;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.<br />
<br />
Example (escape velocity of [[Titania (moon)|Titania]]): M=3.526{{Esp|21}}&nbsp;kg, R=788.9&nbsp;km.<br />
<br />
v2={{v2|3.526|788.9}}&nbsp;km/s.<br />
