ഫലകം:V2/doc

Usage

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

$v_2=\sqrt{\frac{2\times G\times M}{R}}$.

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=3.526ഫലകം:Esp kg, R=788.9 km.

v2=ഫലകം:V2 km/s.
