Mechanics of gravity on the moon

Does someone on the moon fall at 1/6th of the speed on earth or at 2/5ths of the speed?

This has caused much more debate than I anticipated, so I wrote this vb app to prove it one way or another.

What do you think?

    probably apprehensive about downloading the app, or dont have the time.

    I would urge others who can do so to write themselves a similar application.

    It is vital that one observes the difference between two objects dropped : one under lunar gravity, the other under earth gravity.

    Then observe the difference between two similar objects that JUMP : one on the moon and one on the earth.

    It is quite a remarkable insight comparing the 4 examples. Quite remarkable indeed!!!

    Using the constant acceleration eq: v^2 = vo^2 + 2a(x - xo) if you begin the fall with zero velocity and also call the initial x reference zero then the equation reduces to v = sqrt(2gx) for earth and v = sqrt(1/3 gx) for the moon. The ratio of v on earth to v on the moon reduces to sqrt(6) which is approximately 2.45. So when falling from the same distance on both the earth and the moon, the person willing be falling 2.45 times faster on earth than on the moon (at the same relative x position).

    Falling = 2.5~ x difference

    Jumping = 6 x difference

    now see the video
    Jumping on the moon at double speed - YouTube

    now download the app

    then laugh at the fake moon landings

    Japan’s Kaguya lunar orbiter took several pictures of the site, where Apollo 15 and Apollo 17 supposedly landed in 1971 and 1972. If the astronauts had ever landed there, they should have left a lot of equipment on the site, including the rovers, on which they traveled on the surface of the Earth’s satellite. The pictures, which the Japanese rover took, showed not even the slightest hint of the US presence on the Moon.

    where are the wheel tracks?

    astonishing how people repeat what they have been taught without actually thinking about it

    speed is measured as distance over time
    not time over distance damn it!
