Instant Speed?

[Dumbass]

This is another thing I've been pondering over for a while:
When an object accelerates, does it at one point or another go EVERY single speed until it hits a certain desired speed? Or is it possible for an object to go from 0 to say, 60 in literally no time whatsoever?

[shade]

Yeah, you instantaneously accelerate a unit of speed every 1/infinity seconds. Isnt that a mind boggler?

[Nocturnal]

nope, that is impossible. there is a moment, however brief where the object is going at a particular rate of speed.

average speed = distance traveled
----------------------
total time to travel the distance

if time is 0 then that is how fast the object is going at that instant.

[BigMattTheHobo]

an object cant just jump from 0 to 60 without first going through 1,2,3,5,6,7,8..... even if its acceleration is too fast to measure.

[chris_78660]

i agree

Again, I'd use my sexual experiences and say "Yes."

[Unregistered]

Shade is right.

[Instigator]

I'm halfway convinced that this unregistered is Shade. His GF, maybe.

[Bergs]

Because she is backing him up on a incredibly obvious scientific fact?

[Nocturnal]

I think shade is basically saying what the rest of us are saying, there is no true instant speed, no matter how fast the exceleration is there is time involved. This is basic physics,

what makes you think that the person is female?

[Wolfmoon]

yes, but, if your going the speed of light and you turn your headlights on....would they do anything??

[Bergs]

I dont. Instigator called the unregistered shades GF so I just typed she. Whatever, from now on I will refer to unregistereds as "it" until "it" gets a name.

[chris_78660]

or could you even tell because the light would not be traveling fast enough to reach your eyes?
what does it matter? we will not achieve that kind of speed in the near future or ever for that matter. our blood wouldn't even be able to circulate at that kind of momentum.

[Dumbass]

So, let's say that someone is going the speed of light. That means that they are going faster than we can perceive them, right? So in a sense, they would become invisible, wouldn't they?

Our blood doesn't travel as fast as someone in certain jets, like the ones that can go 2,700 mph or whatever it is now. Yet we are still able to live and circulation still occurs.

[chris_78660]

i could be wrong about the blood circulation, but there are black outs and red outs that occur at a few g's....can you imagine the speed of light?

and i guess they would be invisable if they were to 'fly by' us....but i wonder if we were looking through the cock pit of the said vehicle, if we could even see whats in front of us...after all that speed is faster that the image that our eyes capture...

[Dumbass]

Good point. I didn't take that into consideration. Same thing with roller coasters. When you drop down the first big hill, you can't breath, because your diaphram can't expand when it's going at with that much force. So not only would your blood stop but your lungs would collapse. Weird...

[Nocturnal]

jet pilots black out during banking and diving manuvers, where the force of gravity is increased, Linear speed does not have the same effects on circulation

[shade]

Yeah... you only feel G forces during acceleration and deceleration. If you accelerated the normal speed of a car to the speed of light it wouldnt feel any different than driving on the highway. Other than the fact that you would start gaining some weight...

[Delta]

For the high-altitude, fast moving jets, they usually where some kind of pressure suit. Otherwise they would not hold up to the pressure.

If it were a constant and rather slow acceleration than you would most likely be fine. But if you just shot up to high speeds, your own inertia would cause your body to rip apart.

[Nocturnal]

I suppose it would be easy to suggest that if we could go the speed of light we would have some sort of intertial dampening fields, so even super fast acceleration wouldn't be a prob

[chris_78660]

i guess you're right about that...the shuttle travels at 17,580 miles an hour, while in orbit.....that's almost un imaginable

[GM Girlz]

Look at the speed gauge when your driving.
It gose from 1-60 ext as you press on the gas, but it still has to pass every number to get to 60 whitch means it dose have to hit a certin speed to make it to another above it or below it..

We established that a long time ago. The discussion has changed totally.

[Delta]

to get to 60 whitch means

WhITCH?!?!?!

What Witch??

Tell me where she is so I can get my hangin rope and my drinkin buddies so we can have ourselves some fun!!

[Illicit]

The acceleration isn't the problem when appraching the speed of light. The problem is that you can't possibly go that fast.

(clears throat)

As you approach the speed of light, you approach infinite mass. If you were ever to reach the speed of light you would weigh one infinity (maybe more ;) ). Unfortunately you can't, because to accelerate an infinitely massive body, no matter how samll the acceleration, you'd need an infinite amount of energy. Not even the energizer bunny can give you that.

[shade]

Most of the mass gain happens in the last 1% the speed of light. Its in a curve. So, assuming technology could get you to 98 or 99% the speed of light, you would be able to survive it alright. Which is plenty fast for the sake of conventional travel throughout our solar system.

[Illicit]

I'm well aware of that. I just want to make sure that nobody here has any illusions of humans speeding around at warp 8 in the Enterprise.

[shade]

heheh, not unless there is a parallel universe with less surface area that we can go to =P.

fast enough for travel in our solar system, but woefully inadequate for travel anywhere else.

[Dumbass]

Could someone explain the infinity mass topic to me? I just don't know anything about it at all and am strating to get really confused cuz you all know what you're talking about, please fill me in.

[Nocturnal]

from my limited understanding it is how the formula

E=Mc2(squared) works

because of the forces involved the faster you go the more massive you become, and as you approach the speed of light your mass becomes almost infinite. So the object gets heavier, which requires more energy to speed it up. So that is why some beleive reaching the speed of light is impossible. My understanding of the whole thing is fuzzy at best, can anyone break it down further? Physics majors maybe?

[Delta]

But what if you start out at the speed of light??

(Dont answer that, its just a quote from that stupid movie KPax.)
