sometimes, gravity just takes hold and pulls anything that has mass and occupies space towards the ground — solid concrete or soft soil or grassy meadows or murky waters or wherever depending on where you are.
but then again, if it’s not the concrete, it’s towards another object, and that force of gravitation between you two is proportional to the mass of the pullee times the mass of the puller and inversely proportional to the square of the distance between the elements involved — BUT, in this case, though, newton’s theory of universal gravitation was proven false, no amount of distance lessened the F.
so, i’m really sorry.
there was nothing i could do. you can’t fight gravity. no one could.

Boy and girl
If a 50 kg (110 lb) girl sat 0.5 m (19.7 in) from a boy who was 75 kg (165 lb), what would be the gravitational attraction between them?
Substituting the values into the equation, you get:
F = GMm/R² = (6.67*10-11 N-m²/kg²)(50 kg)(75 kg)/(0.5 m)(0.5 m) = 10-6 N or one-millionth of a Newton
That is a very small gravitational attraction, but it can be measured on a sensitive instrument.
Effect of Moon on person
The gravitational pull from the Moon on the 50 kg (110 pound) girl is:
F = GMm/R² = (6.67*10-11 N-m²/kg²)(50 kg)(7.35*1022 kg)/(3.84*108 m)² = 1.67*10-3 N = 0.00167 N
She would not notice the pull from the Moon, since the gravitation pull on her toward the Earth is 490 N. But still, she is attracted more toward the moon than the boy who was sitting next to her.
yeah you have a very good geek point there… hahaha… the numbers says it all… lol…
heya, mac haha, nakuha ko lang yung problems sa source na naka-link. natawa ako nung binasa ko eh ^_^
So paano nga maexplain ang attraction na nagtatagpo ng dalawang bansa? kung bakit na punta from point A to point B si X kahit na isang karagatan ang pagitan?
Dahil napakagaling kong tao, nadeduce ko na ang sagot:
Isa kang planeta.
LAKAS NG HATAK PARE!
Wahahahahahha! Syet bangengers.
meemax oh yeah, i am a planet, indeed.
i am PLUTO — made of ice and rocks.
oh wait, pluto’s not a planet anymore. dwarf planet na lang. halaaa …
(okay titigil na ko, nilublob ko na naman sarili ko haha).
It makes sense di ba? Me sarili kang atmosphere (o hangin) at di sapat na isipin mong sayo umiikot ang mundo, kelangan ikaw MISMO ang mundo.
You’re a planet dude.
And we are the moons that orbit you. Sige iikot lang kami ha? Habang hinihintay namin ang comet na mag-aarmageddon syo. LOL!
Tulog na nga ako. Hehe!
hmm, you’ve been busy… 🙂
i never liked physics… it was always greek to me.
but then again, gravity is something you can’t escape unless you catapult out of the atmosphere, right?
is there a way of stopping an unstoppable force? 🙂
@meemax at dahil sa usapang revolving around a planet na yan may naalala akong dialog namin ni tha sa tren papuntang nikko nung spring.
(ang tinats ay natutulog, ang tha ay saktong magpipiktyur sana ng tulog na tinats, biglang ngumisi at nag-japanese-piktyur-finger-pose ang tinats)
tha: grabehan, may sensor ka yata sa camera.
tinats: ah, oo naman. built-in. ganun talaga eh. sanay na :p
tha: tsk tsk. the world does not revolve around you, you know.
tinats: hmmm. (long pause) actually, it kind of does.
wahahaha.
@tequilabreath yeah, busy is one way to describe the past couple of weeks 😉
re: gravity is something you can’t escape unless you catapult out of the atmosphere, right?
actually, gravity lang ng earth yung na-escape mo :p may gravitational attraction ang bawat piraso ng matter sa iba pang piraso ng matter din. 😉 di lang halata dahil ang lakas ni mother earth. tsk.
re: is there a way of stopping an unstoppable force? 🙂
unstoppable means you can never put a stop to it, you can’t make it stay still, it’s not something that is “at rest” (Ftotal = 0, i.e. in equlibrium — haha, tama na nga physics analogies na naman :p), et cetera et cetera…
teka, i’m lost.
anyhoo, the answer would be no, there’s no way you can stop that. 🙂
geek.
@moogs nagsalita :p
Hey there! ^_^
Somehow I couldn’t find your public comments wall, so I’m just going to say it here.
Hey, did you see that monster dunk by Sylvia Fowles in Spartak’s game yesterday?
It all started with Sue’s defense! So cool. Just see my blog if you wanna see a clip of it.
Just thought I’d let you know. ^_^
@rein_kar_nation oh wow, i’ll take a look at that when i get home 😀 thanks for the heads up.
sorry about the wall thing, i still have to fix its layout 🙂
love this post. (^_^)
eto contribution ko:
“Feels like reckless driving when we’re talking
It’s fun while it lasts, and it’s faster than walking
But no one’s going to sympathize when we crash
They’ll say “you hit what you head for, you get what you ask”
and we’ll say we didn’t know, we didn’t even try
one minute there was road beneath us, the next just sky
I’m sorry I can’t help you, I cannot keep you safe
I’m sorry I can’t help myself, so don’t look at me that way
we can’t fight gravity on a planet that insists
that love is like falling
and falling is like this.”

thanks scout ^_^
