Smart people only please.
 

Please explain the difference between centrifugal force and gravity.

real answer with some intelligence would be nice.....not expecting it but it would be nice...

Centfigal force is the way the planits swing around our sun from a rope, and gravity is the magnets in the Earth core pulling us down.

The effects of acceleration are indistinguishable from the effects of a uniform gravitational field, as per Albert E.

.

ahh but I've heard that isn't quite true - if it's centrifugal force, and you drop something it will fall in a curvature. (ie spinning space ship where you live inside the spinning curve to create gravity from centrifugal force) gravity falls direct line to the center of mass......

but aside from that....they seem like that same force....

centrifugal force is not real, it's for reference.

Think about it like this. cock and balls.

You need to keep in mind these are all just words we term shit we don't fully understand

Idiot 2c.

With centrifugal force, objects are expelled away from the center of rotation.

With gravity, objects are pulled towards the center of mass.

The walls of a bucket travel faster than the center of a bucket, even though they are going the same RPM. Its what makes gear ratios possible.

You win the Mr. Smart Guy award for tonight !:)

There is no gravity.....the earth sucks.

The earth sucks, it's called gravity.

The effects are indistinguishable. To understand both, we need to talk about G force. The effect we feel from gravity and centripetal force are both G force. G force is defined as proper acceleration relative to gravity. That could be linear acceleration, being pages back in your seat in a fast car, or centripetal G force as you accelerate toward to left on a circle track.

Thus in free fall you feel no G force. That's the weightlessness inside a diving plane or falling elevator. Standing on the earth, you feel your arms being pulled down by G force because the "normal" state is to be falling. By being motionless that's 1G acceleration upward relative to the reference state of falling. So that's how you feel G force related to gravity.

How does a centrifuge create G force? What's the acceleration? Let's say you're going due north at 100 mph. Your velocity in the westerly direction is zero. If you turn the wheel to the left, you're suddenly going west. Aha, you were going zero mph west, now you're going west at high speed. That increase in your westerly velocity is an acceleration. Remember G force is defined in terms of proper acceleration, so that's a G force.

Prove it.

gravity is the natural force. centrifugal force defies gravity cause by an acceleration from an outside, not normal, force.

Example:

Everything wants to get pulled into the sun... that is the gravity created by the sun in the solar system. Now earth spins at approximately 24 hours creating our full day. It takes approximately 365 days for the earth to orbit the sun. Now if some outside force accelerated the orbit of the sun to cut that orbit in half, we would not be approximately 150,000,000 kilometers but more like 250,000,000 kilometers.

Closer to mars (which if you didn't know, is further from the sun). That is centrifugal force. A force which defies gravity in the opposite direction.

Similar to a david and goliath sling shot:thumbsup

Curvature is CENTRIPETAL force, not CENTRIFUGAL.

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

centrigugal force is based on the circular motion of an object.
Gravity force is function of the weight and the distance of 2 objects.

These threads make my brain hurt

Centrifugal force (from Latin centrum, meaning "center", and fugere, meaning "to flee") represents the effects of inertia that arise in connection with rotation and which are experienced as an outward force away from the center of rotation.

Gravitation, or gravity, is a natural phenomenon by which physical bodies attract with a force proportional to their mass.

And you wouldn't understand it if you received one...

Anyways, the centripetal force per unit mass acting on the body at the equator is v2/R. This value is negligible compared to g=9.8 m/s2. Gravity will always win.

The Earth would have to rotate once per 1.41 hours, or 17 times faster than its current rate, to toss objects directly at the equator into outer space.

Seeing that you don't live at the equator, it looks like you're safe. I can still dream, though...

"Anyways, the centripetal force per unit mass acting on the body at the equator is v2/R. This value is negligible compared to g=9.8 m/s2. Gravity will always win."

umm stating that gravity will always win with that equation means you don't have a clue what that equation actually means. :2 cents:

sad when a troll grabs something from google trying to make himself look smart when it just shows he's an idiot.

best answer yet, and you seem to have some grasp on this subject of all that have posted so far. but you still didn't answer my question, explaining the difference between the two.


let me take your answer a step further. You talk about G force in free fall. but that's not what I asked. I asked about circular motion and the force in it. If you spin - your arms fling out. you don't have to have gravity for that. It will happen in a vacuum in deep space with no gravity acting on you. the force acts like gravity in reverse (but can be used as gravity if your inside a spinning circle).

so how are they different?

isn't the Centrifugal force an object feels relative to it's mass? a larger object feels more force then a smaller one in a centrifugal force situation - much like gravity?

I answered the question.

For further clarification, you can research how a blackhole works, and then compare that to how a centrifugal clutch works.

This is middle school level science, which means you are a plain dumbass for not knowing the difference.

gravity is equal on large and small objects. Back to school you.

Apparently there's a Higgs-Boson particle they're looking for at the Large Hadron Collider, the "God Particle" which gives all particles weight.

So think of SPACE as a Trampoline... put a 2inch block under 1 side and roll some marbles from the high end to the other. They travel in a straight line.

Now, the Higgs-Boson particle, or WEIGHT is like putting something on the Trampoline, say a bowling ball in the middle.

Now when you roll some marbles from the raised end of the Trampoline, they move in a curve towards the bowling bowl.

So MASS, or the Higgs-Boson particles in MATTER, curve space time like the dent in the trampoline that the bowling ball makes.

The closer you get to the bowling ball, the tighter the curvature.

If your space ship was travelling past Earth, it too would curve towards Earth due to Earth's mass causing curvature in space time, just like the marble curves towards the bowling ball.

So Gravity is the force that results from space time curvature centered around mass.

Now remember the bigger the mass, the bigger the curvature and the bigger the force of gravity, and the closer the two objects, the bigger the force of gravity.

So Newtons formula for gravity between 2 objects is

g = m1 * m2 / d^2

---------

Artificial gravity is just due to your inertia, because you are constantly changing directions going around in a circle you must be constantly accelerating. Acceleration and G force are 2 sides of the same coin.

The rise of the Wikipedia Troll ...

Exactly. Bingo!

Everything you know is wrong... :error

ADG

Until at some point the centrifugal force becomes such a mass that the gravity establishes itself & the object falls in a curve, due to both gravity & velocity of which the force created.

If an object falls into gravity, the only curve would be from an object spinning & creating its own direction of fall or if we are talking about something falling to the earth, of cause the earth is already spinning, so the object would fall in a direct line but of course from where it was dropped :2 cents:

:thumbsup

You made me smile with the "back to school you" comment... very friendly put :)

Centrifugal force doesn't exist, gravity is caused by magnets.

I went from a "Paul Marham is stupid"-post to this :1orglaugh :1orglaugh
GFY´ers always surprises me :1orglaugh

do you say that for everything you don't have an answer for? This guy below seems to have no problem explaining it...

no one really knows what gravity is. it is only a ''word' applied to a 'phenomena' that is observed. for instance, 2 men 1000 miles apart walk due north and eventually meet at the northpole... not knowing about the curvature of the earth they agree on a 'term' to explain why they have met. this is the way the word gravity is used. to refer to an unknown but measurable occurrence

centrifugal force is caused by circular motion, gravity is caused by mass.

The only difference is the direction of acceleration. Standing on the surface of the earth, you're accelerating upwards relative to the natural state of freefall. The ground is pushing you up. Swinging your right arm in a circle from back to front, the arm is accelerating to the left. That's the difference - direction of acceleration.

Hey Arse did you get my message? :thumbsup

you just got hotter :thumbsup what's up with the DP reference in your sig? if you're ever down here let me know

Agreed, but it did say "Smart People only please" :Graucho

this thread makes me hot! so many smart guys in porn. please post more of these threads fellas :thumbsup

We love you for your mind too.
Wanyed to trade - brains for boobs. :)

That is Smokey's geo-ip script at work, it fools a lot of people :)

It will fall in a curve anyway, simply because the walls of the bucket travel faster than the center. Even if its not in a bucket, the same rules apply. Most buckets that I know of, do not have enough mass in the center to affect anything with their own gravity.

Correct, but if the object falling is a compact sphere, is shall roll & probably fall directly down due to the velocity of the sphere spinning & the earth spinning in it's gravitational pull :thumbsup

BTW, what's all the Bournemouth bullshit???? I support Bedford rugby, considering I'm a Bedford Homeboy? While we're here... Shout out for the Bedford massive :winkwink:

The real question is then: "Would the aliens take some extra time to blast the True Man with psionic waves to keep Genesis Adam away from Eve through years of systematic torture?"
