Acceleration Is Gravity

Hmm...

I am sorry theBeardedMan...

This is entirely not correct either...

Acceleration is a component of gravity.

And gravity is an atraction of two bodies that contain mass.... like a type of force.... but an unexplained type of force.

Here is a way of explaining it:

F = ma

where f = Force

and m = mass

and a = accerleration

now the question is what is acceleration?

easy:

a = v delta / t delta ( the "/" is divided by)

where v = velocity

and t = time

and delta = "change in"

a = v / t not gravity.

Acceleration is a component of gravity.

But you were on the right track.

Here is acceleration so they can explain help it more clearly:

Hope this helps
 
Sorry dude... i didn't mean to insult you!

We are all friends here dude!

I can get carried away sometimes... :)

I am hardly ever right so ja! :)

But i know what you meant dude!
 
But yes you are correct TheBeardedMan!

You are right that it is not your point of view!

I apologize :)
It is some1 elses point of view so i have no right to tell you that you were wrong...!

Sorry my bad dude.

:)
 
AFAICR, gravity is caused by the spinning of a larger object pulling in a smaller one (eg a car and the Earth, the Earth and the Sun etc etc)

This principle could be applied to say a space station, a smaller habitation module spinning around a larger main station (with fuel, shuttels etc) at 7 times a minute could provide 70% the level of Earths gravity in said habitation module
 
Hehehe no dude :)

he is just talking about centrifugal force.

Just a slight misinterpratation of the words he used that's all :)

It is still a kind / type force but mechanical that's all :)

http://en.wikipedia.org/wiki/Centrifugal_force

but it was all in good spirit though you see mpw... :)

I know it has gotten nothing to do with gravity... but he didn't mean any harm :) mpw....

Just making converstation that's all...

Yup my bad
Thanks for clearing that up

In gravity objects are drawn to the center, in artifial gravity through cenrifugal force objects are forced away from the center
 
Yes and No... hehehe :)

Shadowninty is correct when he speaks about how the sun "is rotating" causing the sun to "move outwards like a Catherine Wheel" if you can try imagine that in ur mind... :)

He just cud not explain 120 % clearly that's all dude :)

This is why the Earth is a not 100% round or perfect sphere dude... :)

You see... this is why Saturn has a ring a round it.... they say this was because of 2 moons that collided... :( BANG! KRASH BOOM!!

This effect is called the "ecliptical plane" all the planets are in alignment dude :) He meant harm lol hahahaha :)

He is actually a very clever person Shadowninty....

SO.... with this outward movement of the sun it causes the aperture / diameter of the geosphere of the sun or earth to be slightly larger at the equator thus this is why the acceleration of gravity is 9,81 m/s(squared) at the equator.... :) but will be weaker as you get to the South AND north poles.. due to less mass of the earth / sun...

;P

That's what I thought; which works for his space station explanation, but not the earth and sun example he gave, or car/earth.

Sorry, only Space Station was related to centrifugal force [artificial gravity], other examples were releated to gravity

Yup


Any you clearly know far more about what you are talking about than me :)
 
Hahahaa naah dude I like astronomy... lol

What time is it in Ireland there? :)
 
Hehehee lol i can see From ur info I am 007 agent James... lol hahah :)
 
My suspicion is that gravity is somehow related to magnetism, density, and pressure. The rock at the core of the earth is typically magnetized and under tremendous amounts of pressure. It's believed that much of the earth's core is made up of iron (both solid and liquid) and at a significantly higher density than that found near the crust. And Iron is one of the known magnetic elements.

Maybe this somehow contributes to gravity...

Hhehheee! So it is true thebeardedman... you really are a funny guy!

There is such a thing as netiquette thebeardedman... you are correct but try to be more diplomatic in your approach... hehehee lol. :)

Netiquette - Wikipedia, the free encyclopedia

Yes!

This is a very interesting topic thebeardedman has brought to the table!

Yes light does indeed contain gravity because it contains mass... and anything that contains mass... makes gravity. Period.

For example... light can be absorbed and bent by a black hole to take / put things into another perspective.

So if it did not have mass it would not get bent... basically that is fact.

But you get some crazy people out there that believe the earth is "flat"...

Sad. :(

Wow... you need help :)

Are you okay? :)

What are you getting at dude? So i spelt tomething wrong...big deal....people do it ALL THE TIME....

:) Do you get councelling by anychance???
