How does gravity grow through acceleration.

AI Thread Summary
Acceleration in space at 3000 mph per hour results in feeling about 4% of a G, while at 10,000 mph, it equates to approximately 13% of a G. The discussion emphasizes that G's measure acceleration, not velocity, making the initial question about gravity misleading. Participants clarify that the problem primarily involves unit conversion and applying Newton's second law, F=ma. There is some confusion over the phrasing of the original question, but the focus remains on understanding acceleration rather than gravity. Overall, the conversation highlights the importance of clear communication in physics-related queries.

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:
F=ma
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 realized that, I only half read the post tbh.

About 4% of a g

at 10,000 mph?
About 13% of a g

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: :-p

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??
 
  • #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.
 
  • #18
His point is that you specifically thanked Janus, whose answer consisted entirely of
About 4% of a g
and
About 13% of a g
which gives no explanation at all!
 
  • #19
I don't need to know the way you got it if I can find more answers from two.

Arian is trying to learn how to write ...
by knowing that periods go just before Capital letters.
