How does gravity grow through acceleration.

  1. Jun 25, 2006 #1
    If I am accelerating, in space, 3000 mph every hour, how many G's do I feel?

    at 10,000 mph?

    Use Newton's second law and find out.

    It's:
    [tex]F=ma[/tex]
    If you don't know
    (which you probally do know just wanted to make sure)

    Nah, it's just a unit-conversion problem. One "G" equals 9.8 m/sec^2 (m/sec per second) or 32 ft/sec^2 (ft/sec per sec). So he needs to convert 3000 mi/hr per hr to whichever units are more convenient for him.

    If he's rusty on unit conversions, he might want to do it one step at a time, starting for example with

    3000 mi/hr per hr = (3000 * 5280) ft/hr per hr

    Why would it matter how many 'g's you feel at 10000 mph? It would be the same as at 0 mph because 'g's is a measure of acceleration not velocity.

    If you look at the post he/she says 300mph per hour, which is an acceleration. However, he/she later says 10 000mph, but I think they simply forgot to add the 'per hour':smile:
    Yeah, I've realised that, I only half read the post tbh.

    About 4% of a g

    About 13% of a g

    Use Einstein's second law, F=ma

    By the way, the title of this thread, "How does gravity grow through acceleration", is very misleading! "g"s are a measure of acceleration. "Gravity" does not change "through acceleration"!

    Yeah - this is a unit conversion question first, then simply a division by 9.8 second.

    Newton's theory of genial relativity, innit :wink: :tongue:

    Wasn't Einstein's second law never wear the same pair of socks simultaneously?

    Newton, Einstein, whatever - they're all eggheads. Can't tell em apart.

    You! Beer-stein! Do my homework or I'll stuff your head in the toilet!

    Thank you Janus, that is what I wanted to know,
    I already know f = ma.

    You wanted to know the answer, not how to do the question?!?! :surprised
     
  18. Jun 30, 2006 #17
    Well, yes, If you can tell me in an understanable way, with exaples...

    But with the answers I was given I will be able to deduce more answers by using simple algebra.

    His point is that you specifically thanked Janus, whose answer consisted entirely of
    and
    which gives no explanation at all!

    I don't need to know the way you got it if I can find more answers from two.
