ok so from the jets point of view the air would be moving faster in the opposite direction, got it. Thanks for the help hootenanny, and i wasn't trying to piss everyone off by the way, i should have put more effort into understanding the concepts of QED before passing judgement on the topic, I'm...
----|\---- air
=== > jet
----|/---- air
If the jet is moving at 1/3c let's call its momentum p, from a stationary observer it has momentum p and the air around it has momentum zero, but from its frame of reference its momentum is zero and the air's momentum is -p. Stop me if I'm wrong I'm not...
but the air around it is moving in the opposite direction, meaning it has increased momentum in the opposite direction...or am I missing something here?
[edit] and by 'it' i mean the air around the jet
Ok, so it's just the momentum that changes and not actually the mass, that helps. What would that mean for say, a supersonic jet flying at 1/3c, from the jets frame of reference the added momentum should be coming from the air surrounding it, causing more drag as it moves faster, but from a...
naty... http://arxiv.org/pdf/0809.0616v1 . Just because a belief in physics is generally accepted doesn't make it correct. I am not the only person to believe in a particle only description of light, some notable examples are Newton and feynman. As far as I'm concerned, a particle is a particle...
One area of quantum theory/special relativity that I have a HUGE issue with, is the wave-particle duality of light. I firmly believe that a photon is a particle and that some fundamental force is acting on it causing it to behave as a wave. From the little I've read into string theory it sounds...
The problem I see with zeno's paradox is that he is trying to make a finite description of an infinite event. Yes, if you try to measure time as a non-continuos function you have some difficulty but that's because you are replacing continuous time with an interval-driven time, which is not the...
negative temperatures are just negative on the scale you measure them. When they say that nothing can have a negative temperature they are talking in Kelvin's.
Heat is merely molecular motion, so if there is a lack of all motion in an atom it is in its ground state, at absolute zero. Since...
I'm almost done with my flight equations(neglecting spin) this is what i have:
Vt=terminal velocity
Vo=initial vert. velocity
V= local vert. velocity
g=gravity
t=time
Uo= inital hor. velocitysum of Y forces = ((Vt^2)/(2g))*ln((Vo^2+Vt^2)/(V^2+Vt^2))
sum of X forces =...
I was trying to come up with a simple equation that doesn't take into account air resistance, spin, or anything and I ran into some problems.
my equation for the x-axis(horizontal distance) is :x=cos(a)vt
my equation for the y-axis(vertical distance) is :y=sin(a)vt+(0.5*(-9.8))t^2
I then...
Thanks for the reply's...what I'm actually trying to do is create a set of equations to solve for the optimal beruit shot. In the end what I want to do is plug in 2 shots(minimum distance to cup1, maximum distance to cup1) into the formula's and solve for v, then take V2-V1 and solve for the...
I am doing a fairly large projectile motion problem. I am trying to describe the act of throwing a ball from an elevated point at an upward angle into a lower point, while taking into account the affects of ball spin, air resistance, etc.
First, I have a question about the act of throwing a...
