Template:Gr/doc

Usage

This template calculates surface gravity g of a spherical body of the mass M and radius R:

[math]\displaystyle{ g=\frac{G*M}{R^2} }[/math].

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

{{Gr|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 dot in the result (default is 3). The result is expressed in m/s².

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

g=Template:Gr m/s².
