  • If I throw anything out of Earth's gravity well, it will continue to float until it is captured by the gravity of something else.  So, yeah, if an astronaut out a GEO orbit decided to throw a battery away from the Earth, it would just keep on going...

  • Proof indeed that man set foot on the moon

  • weighted feather, obviously never on moon, never went .... he should've shown the feather was real like a good magician would've, hes a hack Naut

  • everyone the real thing about this is that theres some thing called wind resistance (explained by newton) it affects lighter objects more than heavier ones, gravity has the same force no matter the weight of an object , test this by throwing one very very heavy object and a heavy object yes one issignificantly heavier, however neither of them have wind resistance

  • @pt1gard Sigh...The feather is not weighted. Feathers do not fall as quickly on earth because they experience resistance due to wind and atmospheric conditions...The moon has no wind and no atmosphere, hence the experiment works as it should.

  • @TheAJAtom ... the fuck do you know if the feather is weighted or not, move along, nasa troll

  • :-) nasa troll indeed...

  • lol it changes around the earth... everyone just goes with 9.8 though.

  • 9.9 or 9.8 fuck yous all.

  • i had 2 watch this for homework and i just knew id find some nerds arguin about it in comments lol

  • i reckon this experiment proved that we went to the moon. this is aimed at conspiracy theorists

  • I know I sound like a nerd, but that's kinda cool.

  • haha, my teacher was right (:. with no gravitational force. weather the object is heavy or light, both will hit the ground first

  • I can't believe there's a debate on this page! This is fairly basic stuff!

  • There's something I find kind of weird about watching a feather dropping like a rock...

  • what all this about?

  • geeks

  • I won't argue that, but that doesn't change the effects of acceleration, and the inertias don't counter. As I said - it's not enough to dork up spacecraft trajectories and whatnot, but it *is* measurable.

  • No, go read your physics book again. The acceleration is exactly the same.

  • This is one of the cases where physics books are wrong. Yes, I know what they say. I also know the truth of the matter. A bowling ball *does* fall faster than a feather in a vacuum.

    But not by much.

  • No, the physics books and all the physicists are not wrong. Think about this: you have 11 marbles of the same size and weight; you weld 10 of them together and leave the other separate; the welded bunch of 10 will fall at the same rate as the single marble. Even though the 10 weigh more together, every particle (or marble) has the same force working on it, even though the balls fall in tandem. Think about it. Then trust the experts sometimes.

  • Granted, it's wikipedia so you have to take some grains of salt with it. However, it's fully referenced:

    Read the "problems" section

  • You are both wrong. The physics books are correct, but not because every particle has the same force, but because the force of gravity is greater on an object with a greater mass, for Newton's Gravitational Law. And do not confuse mass with weight. Weight is just a convention to measure the gravitational force P=mg, (which is just a special case of Newton's Second Law F=ma).

  • Reread the example in my comment. If you connect 10 marbles together, each with the same mass, it will have 10 times the mass of a single marble that is unattached. The force of gravity is the same on each of the 11 marbles, because each has the same mass. The force of gravity on the 10 connected marbles combined is therefore 10 times that of the single marble, yet the connected group of 10 falls at the same rate as the single marble, even though it has 10 times the mass. Get it?

  • Yes, and that's how it's supposed to be. The force of gravity on the 10 connected marbles combined is 10 times greater because the combined mass is 10 times greater. The force is 10 times greater, the mass is 10 greater, so the rate of gravitational acceleration is the same as the 1 marble by itself.

  • No, wrong

  • Correct. 9.8 m/s^2

  • actually, on the moon, about 1/6th of that.

  • cool story bro

  • absolutely NO 9.8 on earth

  • NO, its 9.8 on earth. wtf are you talkinga bout

  • I said 9.9 ON EARTH!!! not ON MOON!!

  • 9.81

  • sry i wrong typing

  • @dnmry no 9.82 on denmark

  • Gravitational fields are additive, therefore objects that are more massive will have a greater attraction to another body (say, the Earth) than will less massive objects. Therefore, the larger object will experience more acceleration (and therefore travel the distance between the bodies more quickly)

  • And yet larger objects have more inertia and resist acceleration more than light objects...

  • See, an object with mass has its own gravitational field. More massive objects have larger fields, causing things to be caprtured by their "well". This is all relative, of course - a bowling ball has a larger gravitational field than a feather, but when compared to the Earth's field, they are orders of magnitude smaller.

  • @TGBII that would mean if you threw a battery out of earth it will float away to plluto since it has brely any mass

  • Actually, the more massive objects *do* fall faster. Not enough to dork up Copernican rules for trajectories & such, though.

  • "the more massive objects *do* fall faster."

    Do they? Only if you mean that heavier objects have a higher terminal velocity. But in a vacuum any object falls with the same rate as any other.

  • Actually, it has been proven that more massive objects *do* tend to fall faster, and this is held up by basic physics. In terms of sitting on a planet, however, the planet's gravitational forces are so strong that the differenves in the mass (and therefore gravitational pull) of small objects is too small to really notice.

  • why does mass drop from sight when blackhole goes event horzion

  • @glennstapleton for the same reason that mass drops from event horizon when sight goes blackhole

  • galileo was right

  • Oooh... science...
