    NEAS(?) Physics 2oo6 trials

    I did the NEAP trial paper today, and didn't expect how easy it was. Pretty sound with my calculations and regurgitating the theory wasn't hard. I'm not expecting any real overlooked mistakes (maybe just a mark here and there). Exam went for 3hrs, and had finished section 2 bar elective in...

    HSC kiddes

    I had a thought: For a plane to take flight, wouldn't the aircraft have to move relative to the air at a critical velocity to a point so that the plane's wings undergo the Bernoulli effect? As far as I'm aware, this is required for the plane to take lift. I think that may answer the question :)

    Chemistry HSC Books

    Hi, just wondering if anyone is having any problems with answering the new HSC dot point syllabus questions. I'm using two Chemistry textbooks, Longman's Chemistry Contexts (2002) and MacMillan Chemistry Pathways (2001). I have school classwork, however most of it is a summary of either of...

    can someone confirm this idea on momentum

    gman beat you to it, but yeah that basically all the analysis we can do for you wolf. So, yeah.

    can someone confirm this idea on momentum

    Sorry i was just trying to clarify wolf's argument, as he did state such. I was bit worried he might get the wrong idea that both applications share the same concepts. In fact i just noticed this: This equation has to do with the equivelence of the net force of differing variables, not the...

    can someone confirm this idea on momentum

    This case i would regard that it is the conservation of momentum within a system, rather than before and after, for the event is simultaneous, the momentums exist at the same time. Just an observation. And to clarify, it isn't really another theory, they are different applications of finding...

    what the definition of momentum

    The fact that this definition includes the word 'inertia' make the definition look misleading, but is essentially true. But i would rather change 'change of motion' to 'change in direction of motion', for if you consider a falling object that has a massive booster behind (looking from earth)...

    time dilation and the paradox thingy

    One thing clear. The spaceship twin will be physically younger. Say, the earth twin thinks that the trip of the spacecraft is 4 years, and the spacecraft twin thinks the trip was only 1 year. They dont feel that time has slowed, for everything in time dilation is slowed (including processes...

    ...Gravitational Potential Energy...

    Yeh its like that, but i like to see the whole thing as: a gravitational field doesn't store energy into an object, it rather provides masses kinetic energy, the OPPOSITE to potential energy, and in that respect you see the logic of the negative sign, for there is negative potential energy...

    Traveling at the speed of light!

    My Opinion Regardless to black holes, i would say that relatively speaking, the earth feels less acceleration than a spacecraft travelling close to the speed of light would. But the Earth does experience acceleration due to its rotation and revolution around the sun (ignoring accelerations...
