A few questions, math/science

I have a few questions for an equation I'm thinking of.

A exertion of force from an object, like a muscle, reduces the mass/volume of the object, in theory, correct?
Therefore the more force exerted, the less of the original object is until it recovers. Like a glass of water, you pour out so much water to accomplish something, and then the water in the glass is reduced until replaced.

And is there a scientist/mathematician who has a similar thesis/equation for this?

Hey J,

Mass and volume are completely different things. Force is mass times acceleration, so the only way to exert a greater amount of force on something is to increase either the mass or the acceleration, not decrease the mass.

Maybe I'm not understanding you. I'm not sure how an object exerting force decreases either mass or volume.

There are reasons why I'm asking for assistance in this matter.

Essentially, what I'm aiming for is a mathematical equation that more or less says "The more you're a censor.gif in a game, the more your censor.gif shrinks. Therefore, based on this equation, I'm judging that by this move you just pulled, you're fairly small. Really, I know squirrels to be packing more heat than you."

Also: "SCIENCE! dictates that you have a small censor.gif."

That is the only way to say SCIENCE!, by the by.

Well... This isn't my field of study at all, but let's try extrapolating from e=mc^2.

e=energy, m=mass and c=speed of light. Since the speed of light never changes, the energy is directly dependant on the mass. So, in order to use energy (i.e. e will be negative) your mass will also be negative.

I think it's wholly unapplicable to the above scenario though tongue.gif

EDIT: Hmm. Wouldn't it be possible to say de=dmc^2? I.e. the more censor.gif energy used, the smaller the censor.gif will become.

I imagine Albert Einstein just started rotating in his grave though...

Well, the extra mass for the additional force has to come from SOMEWHERE.
Moriana2010-09-16 20:08:35
Well, if you want to say the amount of effort/force used is inversely proportional to mass, you can just say:

E = 1/M, where E = amount of effort and M = mass.

Or, in your case:

Amount that you're a censor.gif in game = 1/Size of your censor.gif.

Does that work?

You're just bothered by their nuts, aren't you?

Jigan, if you mean "moving an object makes it marginally lighter until it is at rest again", technically that's part of the theory of relativity.

I'm sorry. I'm so sorry. You brought this on yourself, though.


Einstein's theory of special relativity deals with changes in length to prevent paradoxes from happening and break downs in events happening at the same time. However, no matter the velocity, however, mass will will always be the same (and since weight is a function of mass and delta velocity, weight would stay the same so long as we're talking about a force fully in a y direction with movement fully in the x.)

Now, I have yet to bring up the law of conservation of mass and energy. Ahh, there it is. Matter nor energy cannot be destroyed, they can only change forms and change between each other. The latter only happens in a nuclear reaction. If there is a nuclear reaction inside your body, I'm sorry.

So, as far as I understand, you're not going to be messing with your mass.

whatever, that's what I always thought. I stand corrected.

Sorry, I had to. Is my field.

This is incorrect.

An increase in velocity, thus an increase in kinetic energy, causing a necessary increase in mass of the object in order to fulfill the mass-energy equivalence E=mc^2, though this is not notable to us until approaching speeds nearing c.

This is also why it is impossible to accelerate to the speed of light - as you move faster, you gain mass, and as you gain mass, you require more energy to continue accelerating. Mass, however, will approach positive infinity, meaning you would need infinite energy to continue acceleration to c.

Anyone up for discussing relativity and how it relates to spatial and temporal movement? I'd sure love to teleport one day.

teleportation is real and has already been done in the lab.

Yes, I know that, but he specified a decrease in mass which would never happen.

So Jigans insult goes out the window, but you could say 'Blimey, you're moving so slowly I swear your censor.gif must've shrunk as a result', I suppose.
