i know that mach 1 is the speed of sound, but i was wondering how many G's it is, and if a "Gravity" is a measurment of speed what would it be to mph? or is "G's" a measurment of force? if so, how would one describe how many "G's" one would be going/expierencing if we were in a zero Gravity environment? and, how many mochs would some body be going if he were going 1Astronomical Units/hour (93,000,000mph)? I've heard certain designations for g's with speed like: a person expierences 6 g's going 70mph down a free way or on a roller coater, or one expierences 9 g's during re-entry into the earths atmosphere. i'v also seen speed limitations for some jet fighters being mach 14, how many mph is a moch? and since moch is the speed of sound, and there is no atmosphere in space to project sound, would a person hear a sonic boom once a craft were to hit the speed of sound in ourter space? and, would the same "boom" effect happen with light at the speed of light?
if this is too much, or if you don't understand because of spelling mistakes, I am sorry. I have been researching these for a game i am making, and i want to make it's mesurements as acurate as possible. please send your answeres to Remo24@excite.com, or to Michael.Ray.Saxton@us.army.mil thank you very much for your time
