• Starting today August 7th, 2024, in order to post in the Married Couples, Courting Couples, or Singles forums, you will not be allowed to post if you have your Marital status designated as private.

  • CF has always been a site that welcomes people from different backgrounds and beliefs to participate in discussion and even debate. That is the nature of its ministry. In view of recent events emotions are running very high. We need to remind people of some basic principles in debating on this site. We need to be civil when we express differences in opinion. No personal attacks. Avoid you, your statements. Don't characterize an entire political party with comparisons to Fascism or Communism or other extreme movements that committed atrocities. CF is not the place for broad brush or blanket statements about groups and political parties. Put the broad brushes and blankets away when you come to CF, better yet, put them in the incinerator. Debate had no place for them. We need to remember that people that commit acts of violence represent themselves or a small extreme faction.

Much beter though it would be beter to use:

a=GM/r^2

since "g" is aften used for acceleration due to gravity which is not what you want.  But that is a nitpick since any symbol can be used for any variable so long as one is consistent.

yeah, i was being lazy and typed a lower case "g" instead of "G"..so in this case, g=G

In case anyone is interested, Rising_Sun's equation can be obtained by substituting f=ma into Newton's equation for gravity which I gave in a previous post. One of the m's cancels out (the one we interpret as the mass of the Earth).

that's exactly how it's done. :)
