I meant aphelion, sorry.

...dude give me some time, trying to compensate for drag due to humidity and temp, cross-sectional drag, effective potentials of the earth, sun, and moon ( and now that I think about it, maybe mars) is not trivial. Then I have to find the apogee and perihelion of the orbit of the payload to...

So if I take a vector and expand it throughout some arbitrary plane it makes a field?

Challenge accepted.

Hey everyone, I was just wondering can a vector be expanded into a field? I.e. take a gravitational potential that can be described by a vector (F = -\nablaV). Can this vector then be expanded into a field given a plane with the point of attraction at the origin, for simplicity. Thanks

Lame, this problem is like inception...you can always go deeper.

...not necessarily, we must not forget that the Earth itself is moving with a speed of 29.78 km/s around the sun. So if a projectile is launched from the surface of the Earth traveling in the opposite heading of the Earth it is possible to find a point SOMEWHERE above the Earth where the...

I agree, but I am trying to find a quantitative method of proving this rather than qualitative.

This is a great point, there should always be a buoyancy effect; on earth, buoyancy is a consequence of Archimedes principle, it is clearly observable due to Earth's great mass and therefore formidable local gravitation field. However, a globular formation of water in space will still have a...

Actually I believe the minimum escape velocity for an object is 11 km/sec. And just off the top of my head you could do energy conservation to calculate its final velocity after air and gravity have performed work on the payload.

Hey guys, What exactly does a nonholonomic constraint tell about a system. For instance I am working on a goldstein problem and it has raised the importance of interpreting what a constraint really does. I understand what a holonomic constraint is and what it tells me-for one the motion is...

Hey everyone, I am working through all my graduate texts a couple problems each simultaneously to begin to see any overlap in physics. Anyhow, I started working on Jackson and the first problem has me using Gauss's theorem to prove any excess charge on a capacitor must exist on the surface...
