For Woodsman25 - Under an assumption of constant gravity, Newton’s law of gravitation simplifies to F = mg, where m is the mass of the body and g is a constant vector with an average magnitude of 9.81 m/s². The acceleration due to gravity is equal to this g. An initially-stationary object which is allowed to fall freely under gravity drops a distance which is proportional to the square of the elapsed time. The image on the right, spanning half a second, was captured with a stroboscopic flash at 20 flashes per second. During the first 1/20th of a second the ball drops one unit of distance (here, a unit is about 12 mm); by 2/20ths it has dropped at total of 4 units; by 3/20ths, 9 units and so on.

It should be kept in mind, of course, that the numbers given are applicable on Earth, with its gravitational field of 1 gravity (1g). The numbers would be different on Mars (1/3g), the Moon (1/6g), or Jupiter (approximately 4-6g, depending on how you define its "surface"), for a few examples. The equations, obviously, still work.

True; no data given on the Wrong Planet though!

Gravity doesn't even exist; it's just an effect that mass has on the fabric of space-time. How can it be good or bad if it doesn't even exist? The effect that mass has may be beneficial or harmful depending on how it is used, but these properties don't belong to "gravity" itself.

Oh, come on guys
:roll:
:lol:

If gravity didn't exist there'd be nothing to counter Dark Energy and Matter
and the Universe would be a couple of Trillions bigger in size
roaring out into the infinite at the speed of light with nothing bigger than a nucleus and an electron
:!:

maybe not even that...

The fictitious force called "gravity" is caused by mass warping the fabric of space-time.

This

is as much a real force as

so you're proving the existance of a ficticious force and then denying it's existance?
