some hypathetical questions i've been trying to research,

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

G's are a measurement of force. A g-force of 1 G is what you're experiencing right now, sitting in your chair.

if so, how would one describe how many "G's" one would be going/expierencing if we were in a zero Gravity environment?

You just answered your own question. You would experience 0 G.

and, how many mochs would some body be going if he were going 1Astronomical Units/hour (93,000,000mph)?

They would be going at approximately mach 122,116.

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?

mach 1 = 340.29 metres per second (approx. 761.21 miles per hour)

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?

You answered your own question again. No atmosphere = no sound = no sonic boom.

and, would the same "boom" effect happen with light at the speed of light?

Either that, or the universe would implode. Either way, surpassing the speed of light is impossible, according to Einstein.

The fastest aircraft used by the us military is only rated for mach 3.3 or so. No aircraft or rocket was ever designed to go faster then mach 7. However, newer aircraft engine designs have reached the feasability of traveling at mach 7+ but these are still only theoretical. Aircraft rated at mach 14 would build up an extreem amount of heat causing the metal alloy covering the aircraft to melt. The speed of mach 3.3 causes enough heat buildup to cook a hotdog on the inside of the canopy covering the cockpit.

does anyone know at how many g force your body implodes?

Many thanks...

Actually NASA has a new X-43 that goes Mach10 by breathing air fastest speed ever by air induction. 7,000mph

all i know is that i have a question still not answered by the topic

how many g's are in a mach 1

your G force at mach one will be 1 G because your body and your vehicle have finished acceleration. If your question is what is the G force while reaching mach 1 it depends on what your rate of acceleration is.
