ZERO-G

[XSP-Xenon Space Programm]

I think you know what a ZERO-G flight is.... Otherwise you can use google... ;D

You can use all parts but C-7 would be the best, i think

[Iskierka]

The problem with this challenge is actually performing a flight that is zero-g, with no way to measure.

Also the fact that it\'s something basically any aircraft can perform.

Too easy, add more detail...

It\'s still easy... weightlessnessis achieved when you are freely under the influence of gravity. Thus, being in a simple free-fall achieves it. In fact, as just having your engines off is weightlessness, no matter what direction you are travelling. As long as the ground isn\'t in the way, and you aren\'t applying thrust, you are weightless.

Oh, the reason I say 'weightless' is because zero-g is impossible. Zero-g implies zero gravity; that is, no gravity at all. However, because gravity still exists everywhere in the universe, it\'s impossible to not be under the influence of it, even if it\'s only in minuscule amounts. In ksp, zero-g is technically possible however, due to rounding numbers when the number is incredibly small.

[Iskierka]

Wrong, it\'s both easy, and basically impossible, because there\'s no way to confirm. Having engines off in atmosphere is not weightlessness; lift from wings and drag from everything apply force to the aircraft, which applies force to the occupants. Thus, it is not a zero-g environment. This challenge could not be completed within the atmosphere ... and everyone who has left the atmosphere has achieved this anyway.

Also, shush, zero-g does not imply an absence of gravity. Zero-g means the apparent body force experienced by anyone or anything in that situation is zero g\'s.

[Tim_Barrett]

Isk is correct. The term zero-g is kind of a misunderstood statement and play on words.

Basically it is seemingly no difference in movement in relevance from your perspective.

Couldn\'t you just determine it by measuring your hang time, start speed and end speed. Average it out, do some math, and determine if you\'re average acceleration was 9.81 m/s^2?

Then make the challenge whoever gets an average accel closest to 9.81 wins?

I remember doing this a lot in physics with throwing a ball in the air, measuring it\'s total hang time, divide it in half, then we found the the velocity at impact and such.

So you could calculate your acceleration the whole way down by your end speed. If you burn to compensate for drag, then your acceleration should be closer to 9.81

If you don\'t burn, it would be a little lower. Right?

That measurement of how accurate your 'zero-g' velocity would be unreliable because the atmopshere is way too small and varies too much from the altitudes.

So I think the challenge is to fly a parabolic arc so that the kerbal crew would be in a sustained state of weightlessness throughout the maneuver? Is that the challenge?

If so... this isn\'t difficult at all to verify. There\'s a G-meter right next to the navball. Record a video of the maneuver.

I bet this will be difficult to fly.

[Iskierka]

Except if you\'ve ever paid attention to that g-meter through odd manoeuvres, you\'d know it\'s a far from reliable measure of ... anything, really.

It never goes below 0
