How Fast are We Going?

edited March 2013 in General Discussion
As a result of a kid's science experiment, I got to thinking too much. The Earth spins once every 24 hours and it's 24,875 mi. around. Therefore we're going 1,036 MPH or a bit faster than a .44 magnum bullet. But, at the same time, the Earth is circling the Sun on a course that is 92,960,000 mi. in radius. Since it makes that circuit in a years time, that's 584,086,272 miles per year or 66,631 MPH! Now my question: Is the Earth rotating with or against its orbit; IOW, are we going 66,631 MPH - 1,036 MPH or + 1,036 MPH? (Assuming without NASCAR)!

    Depends upon where you are on the earth and what time of day its is.

    The side of the earth facing the sun is moving with the orbital speed and is thus additive. The side facing away from the sun is moving against the orbital direction and is thus subtracted from the orbital speed.

    So, at the poles and at 6:00 am and 6:00 pm, our speed is the orbital speed. When at the equator at midnight and a noon, the speeds are added or subtracted as above.

    At different times of day and at differing latitudes, the speeds can be figured based upon angle from the sun and angle from the equator.

    Please note that none of the above takes into account the 26? tilt of the earths rotation axis. This will change the rotational speed vector, and, frankly, is a large pain in the * to calculate.

    You can't just add or subtract the Earth's rotational speed to it's orbital speed, as these 2 speeds are only along parallel paths for 1 nanosecond each day......

    Of course the Solar System is also speeding along, as is the galaxy. And the universe is expanding. We are on the move!

    Some of us are having a hard time keeping up.
    Some will die in hot pursuit
    And fiery auto crashes
    Some will die in hot pursuit
    While sifting through my ashes
    Some will fall in love with life
    And drink it from a fountain
    That is pouring like an avalanche
    Coming down the mountain

    But what if you are Dale Earnhardt going into turn one at 198 MPH facing north?

    Then you'd be starting to drift. Is that legal in NASCAR?

    I read somewhere that this solar system is hurtling
    at 18kmph thru space.
    I prolly have the numbers all messed up.

    Not exactly. Although he could give us an answer too, but I was thinking of a correct answer!.

    Well that is the heart of the matter.

    I'm fairly well convinced that Keppler was wrong. That planetary motion is an illusion.

    And if you are on the freeway traveling westward you can add 60mph to the total plus or minus a few mph.

    Now that I have googled 'GTFOoH', I must say this seems extremely impolite.[:)]
