problem with units of an equation
[edit]Can someone check the first equation for the ellipticity vector (involving the angular momentum h)? It should be unit-less but has a unit of mass from the angular momentum h. Using "m^2" in the denominator would fix it. The second equation for the vector is correct. 98.114.178.67 (talk) 18:18, 15 February 2011 (UTC)
- The h vector is the specific angular momentum equal to r cross v, so it has units of m^2/s. I've edited the section to try to be a little clearer about this. Jaxcp3 (talk) 01:21, 31 January 2013 (UTC)
