Quote from: AlphaFire X5
F=ma   The most basic definition of force
F=mg   For when you're calculating something's weight (the force due to gravity)
No, this is wrong.  If your want to calculate someone's weight, it's still F(weight) = ma, where a is acceleration caused by the force of gravity.  The accleration caused by the force of gravity happens to be (darn near) constant on earth, since the force of gravity is directly proportional to the mass of the object involded, but that doesn't mean graivty is acceleration.  Any dictionary or encyclopedia will define gravity as a force.  In fact Encarta, the source you quote, suggest "graivitational force" as a good synonym for gravity.  

And graivty certainly is not directionless.  The force of gravity excerted on one object by another object is in the direction of that object.

However, I'm willing to entertain the idea the gravity is not a force, if you want to get into non-Newtonian-land, and go with the Einsteinian "gravity is a distortion of space-time".  But as long as we stay in the world of Newtonian physics (which we've done so far), nothing will convince me that gravity is not a force.  It's one of the fundamental forces, for Christ's sake.  That's fundamental forces.  Not funalmental accelerations.  :P

But I say we leave this up to popular opinion, relax, and have a beer.

No no, GRAVITATION is a force. That I will concur. However, gravity in and of itself is not a force. There is gravitational force, but gravity is an acceleration.

AlphaFire.  Although your argument in of itself could be considered semantically correct... taken in the context of my original post, you're completely off-your-rocker (wrong).  Not because of any scientific definitions... but simple English grammar.

I said force of gravity.  In this case, gravity is an adjectival modifying force..... so whether gravity or not is a force is completely irrelevant since it acts as a descriptor.

Example: Strength of character - a 'character' isn't a 'strength' and it doesn't have to be.... its simply describing what kind of strength the speaker is referring to.

And I'll mantain that making a distinction between gravitation and gravity is the silliest thing I've ever heard.  :P

Agreed. Given that gravity creates gravitaion and vise versa.

Quote from: AlphaFire X5Nuh uh! Gravity isn't a force! Force is mass times acceleration. Gravity is measure in m/sec^2. Thusly, it is an acceleration. Gravity has no mass, ergo it is not a force.

But, what about the phrase, "The Force of gravity", and isn't a mass required to induce the force of gravity?

Yes.  No one is arguing that.  In this case, the mass of (primarily) the earth is interacting with the mass of gasoline, causing the force of gravity, which accelerates them towards each other.  Since the gasoline is much lighther than the earth, it acellerates much faster (9.8 m/sec^2) than the earth (which hardly accelerates at all).

Gravity is a force ... that 9.81 M/sec/sec or 32.2 feet/sec/sec is usually called acceleration due to gravity ...
Cool.

Alright, well, I found it out. If you're talkin' science and stuff, you've got to differentiate between gravity and gravitation or else you're wrong. They describe two different things.

Gravitation (or gravitational force) is a force unit, whereas gravity is an acceleration unit. Had he said the force of gravitation, I would have been cool with that. Most people don't make the distinctions with the exception of physics majors, people who do a lot of physics, or nerds.

And TB, I'm an engineer, not an English major! :lol: I was thoroughly confused by that until I looked at it carefully. To which I say, "Damn the English language and its complexities!"

Alpha- I'm an engineer too.  A helluva chemical engineer (Ramblin Wreck from Georgia Tech).  I disagree that being technically trained disqualifies you from having a competent grasp of grammar and the english language.    Its being an American does that!  (Ha-ha, i'm an american too though).

It's not that I don't have a strong grasp of the language, it's just I don't really care.

I guess now I am arguing about semantics. All this silly gravity talk should be diverted to the Odds 'n Ends thread we started.  :thumb:

Quote from: TarzanBoy... Instead of panicking, I relax...concentrate... and remember my jedi training (cue star wars music!)....  

Managing a reasonable speed, I reach behind my knee, and activate the reserve...  using the FORCE (of gravity) to feed fuel to the engine.   4 seconds later, my engine stops coughing and powers back to normal.  I take the next exit and pull in at the nearest gas station. ...

This is the 3rd time that i've run out of gas...
Run out of gas you have not!! Need for reserve you have!

Not ride to gas station if you run out of gas.  :thumb:
