• Is a vacuum needed for checking speed increase due to gravity?

    From Dave@21:1/5 to All on Wed Jan 4 17:04:03 2023

    There is doubt about whether gravity speed increase should be m/s^2, or
    m/s per meter descended.

    Checked the price of 60m of 250mm diameter, 5mm clear polycarbonate
    tube, and it is about GBP 20,000. A bit beyond a hobby budget, but OK
    for a regional science centre or university.

    The next best thing might be a steamlined body. Dropping this would get
    you an exact time of start and finish, and be filmable for confirmation.

    However not sure yet if there is the accuracy available to tell the
    difference. The good news is that it is in within many people's
    entertainment discretionary spending limits. Say USD 300 for the item,
    and about USD 60 for each drop, which may be destructive of parts.

    I would say don't go for crowd funding on this, likely get the money,
    but then reluctance, prevarication, and total apathy from anyone you are
    paying to do any work. (riggers, planners etc.)

    Since this is also posted to alt.conspiracy, the new angle here is that
    the Americans went to the moon, but the rockets etc they used to go and
    come back don't compute with generally accepted classical physics.

    Kinetic Energy = 0.5mv^2.

    My working hypothesis is that kinetic energy is proportional to v.
    There are many and various implications from this including how gravity
    works, and also then general relativity and possibly rotational inertia
    (which is needed for flying saucers).

    From a rocket sled thought experiment it is clear the generally
    accepted classical physics is inconsistent. (There is free energy
    generated).

    Only by you.

    For the rest of the world the question was settled hundreds of years
    ago.

    Any science centre or university already knows that answer and has no motivation to do this other than for an educational display.

    Streamlining has nothing to do with timing or filming.

    Accuracy of what?

    The good news is that it is in within many people's
    entertainment discretionary spending limits. Say USD 300 for the item,
    and about USD 60 for each drop, which may be destructive of parts.

    Or a box of assorted fishing weights for $12.

    I would say don't go for crowd funding on this, likely get the money,
    but then reluctance, prevarication, and total apathy from anyone you are paying to do any work. (riggers, planners etc.)

    Do you need crowd funding to afford $12?

    The Apollo 15 mission also dropped a hammer and a feather on the Moon on
    live TV broadcast to the entire planet.

    Kinetic Energy = 0.5mv^2.

    So far the only thing you have said that makes any sense.

    My working hypothesis is that kinetic energy is proportional to v.

    The is because you are an uneducated twatt waffle when it comes to
    science and math.

    There are many and various implications from this including how gravity works, and also then general relativity and possibly rotational inertia (which is needed for flying saucers).

    Actually the only implication from this is that you are a crackot.

    From a rocket sled thought experiment it is clear the generally
    accepted classical physics is inconsistent. (There is free energy generated).

    Also implicates that you are a crackpot.

    Thought experiments don't generate testable data.

    Yes, I would pay like USD 25.00 to see a good drop and film it, for confirmation either way. Education has value.

    It has everything to do with timing and the way to can interpret
    results, due to terminal velocity.

    Height is easy to measure now with laser measures. Start from various
    heights and get a timing profile. Not sure if you need profiles during a descent.

    However not sure yet if there is the accuracy available to tell the
    difference.


    Accuracy of what?
    Accuracy of timing, and a decision as to whether the speed does up with
    the time of the drop, or the distance dropped.

    entertainment discretionary spending limits. Say USD 300 for the item,

    Raise USD 100,000, don't spend it properly and deliver the goods (either

    Spending USD 100,000 on a vacuum drop unless you're wealthy isn't

    A practice that stopped well over a hundred years ago.

    There is also a very big difference between making observations on the
    laws of physics and experimenting with humans to see what happens, i.e.
    that latter is very highly restricted.

    Or you could pay nothing and just watch the video from the Apollo
    mission.

    Nope, wrong once again because of your poor math skills.

    Height is easy to measure now with laser measures. Start from various
    heights and get a timing profile. Not sure if you need profiles during a descent.

    Height is easy to measure with a tape measure and as there are no
    magical distances over which the laws of physics change, it does not
    take very much height to do a good experiment over short distances.

    A trivially doable experiment would be to drop various lead weights from
    a 3 M pole and verify they all hit the ground at 7.7 m/s.


    However not sure yet if there is the accuracy available to tell the
    difference.


    Accuracy of what?
    Accuracy of timing, and a decision as to whether the speed does up with
    the time of the drop, or the distance dropped.

    Utter nonsense because you have no understanding of math or physics.

    It goes up with both, muppet.

    entertainment discretionary spending limits. Say USD 300 for the item,

    In my thinking there's enough evidence to say "The facts will be
    presented to the court."

    i.e. not a record of the fact, but
    1- an air track with collisions (hard and soft) and kinetic energy
    lifting a weight stack. Who says a courtroom is stuffy?
    2- a day out with drops measured by stopwatch- no possibility for
    fiddling. Hopefully in a vacuum tube. Different items, no possibility
    for secret fast spinning to change anything.

    Each metre descended gives the same loss of potential energy, and the

    goes up with the square of the velocity, the latter does not increase at
    a constant rate per metre descended. So m/s per metre descended is a
    useless measure.
