Oh man, have you got that right. On the other hand, it is good for keeping us on the planet.

yes, I think I can live without it.

9.81 m/s2

Gravity is wonderous. Otherwise, if I spilled liquid, where would it go? I love the comfort that I in fact know!

Yeah, but then we wouldn't exist :D So I voted good

isnt that how fast an object falls or gains speed while it is falling up until terminal velocity???

Just wanna make sure, its been many years since I have left collage and kinda felt that since I left I have gotton progressivly dummer since I am not using those parts of my brain anylonger.

With less gravity, we could go colonize other planets with ease.

I voted good because it's the only thing attracted to me at the moment. :D

with less gravity, we wouldn't have an atmosphere...;)

with less gravity we would all be taller.

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.

Under the same constant gravity assumptions, the potential energy, Ep, of a body at height h is given by Ep = mgh (or Ep = Wh, with W meaning weight). This expression is valid only over small distances h from the surface of the Earth. Similarly, the expression h = v2 / 2g for the maximum height reached by a vertically projected body with velocity v is useful for small heights and small initial velocities only. In case of large initial velocities we have to use the principle of conservation of energy to find the maximum height reached. This same expression can be solved for v to determine the velocity of an object dropped from a height h immediately before hitting the ground, , assuming negligible air resistance.

I don't know about the rest of you...but I take comfort in the fact that i stay on the ground. Gravity is good.

Gravity is the greatest opressor of all times, and she has brainwashed so many people into thinking that they are better off with her.

But really, what has she ever done other than keep us down and crush those who opposed her?

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.
