APOLLO 15 Hammer and Feather

[hornetgreen1]

It faked with a metal rod in the feather

[wrraith450]

@hornetgreen1 You're aware that it wouldn't matter if it had a rod in, right?

[miln40]

I wonder if those beeps are censor words haha ;) Apollo missions are aaaaawesome

[bears7777777]

in Soviet Russia, feather falls faster than hammer. :-)

[revivalero25]

yo practico submarinismo y si se fijan cuando tira la linterna es el mismo movimiento que hace en el agua, atencion al mango de la linterna, esta realizado en una piscina o algo parecido....

[kiowa2000]

@revivalero25 NO es una linterna lo que trae el astronauta en la mano derecha, es un martillo, (hammer) como se titula el experimento, un martillo y una pluma caeran al mismo tiempo sin resistencia del aire por falta de atmosferia. Me gustaria ver una linterna y una pluma caer al mismo tiempo dentro del agua. (como es posible que haya gente que todavia crea que los viajes a la luna fueron un engaño).

[psychonaut25]

Stop!! Hammer Time!!

[orientalarab]

1:20 Amazing experiment!! but clean up afterwards dont leave feathers and hammers on the ground. keep the moon tidy guys ;)

[dleksi]

Ok i was wrong about Scot- Allen talking delay.

[dleksi]

167:21:58 Scott: Joe, I hope you have a good picture there. I've got...

167:22:02 Allen: Beautiful picture there, Dave

that is official transcript.

Is that code for start filming? Is that what we really hear or we have here Allen's interjects with "beaut..." . I think this handsome young controller Allen was little nervous and we can hear that. BUT WE SHOULDN'T. Think about 2.5 sec delay there are no chance for interjecting (beaut...) and immediately replaying(beautiful picture there,Dave).

[roamingcroat]

@dleksi Keep in mind, this is being recorded on the Earth. So, when Dave Scott or Jim Irwin says something, Mission Control heard it, and it was recorded at the instant it was received. CAPCOM could reply instantly, and that recording would also be on record as soon as it was said. So the scenario is: [Scott speaks] [~1 second later, mission control hears it] [CAPCOM responds] [~1 second later, Scott hears it]. Therefore, there is no delay between Scott and CAPCOM speaking on the recording.

[dleksi]

If you look original video on nasa site about 80 MB frame by frame you can see that one frame is suddenly lighter almost 50 % and two frames are almost identical at the very and of fall when they had slightest chance for that. This part is for sure video enhanced frame by frame. Where is original master video?

[roamingcroat]

@dleksi You have to be careful when looking at this video frame by frame. It is not a film, but rather a TV transmission. Furthermore, a color wheel spun in front of the light sensor - roughly speaking, it captured three separate frames 1/20th of a second apart for three different colors, and then equipment on the ground combined the frames. The way this combination worked, some frames were repeated. Plus, how this video was digitized could come in to play.

[MrGingaNinja71]

this is not fake :)

[jkdcat]

@Elena9545

Yes, this is true. They are correct. However they have forgotten the second important fact that goes along with this. Along with greater mass and therefore gravity, come greater inertia. This resistance to change in velocity effectively cancels any advantage a higher massed object might have in a race for the ground. As long as they're in a vacuum, ANY two objects dropped at the same moment, and at the same hight will ALWAYS hit the ground together. (remember, in a vacuum, that means

[Elena9545]

>.> Some morons at my school desperately want to believe what's contrary to this video -- that is, an object with more mass will fall faster than one with less. Why? They claim gravity has more of an effect on objects with greater mass. =(

[okendido]

@Elena9545 Technically they are right, but for the effect to be noticeable you would have to have massively huge objects.

[Hypsan]

Playing the devil's advocate, or pretending to be one of those misguided Moon landing hoaxsters, I could insist that it wasn't a feather at all, but rather a piece of metal carefully made to look like a feather. I mean, if we can put men on the Moon (dig! dig!), we certainly should be able to make a piece of metal look like a feather. ;-)

[bengacris]

@Hypsan yeah so?

[cjk98]

Why don't they show this shit in schools?

[screamobassistxx]

@cjk98 they do. i just watched this for an assignment

[tpsossff]

@cjk98

Why don't they show it in schools? Dunno about the US but in the UK they don't do anything that might offend some ethnic group. The sight of astronauts on the moon no doubt upsets some West hating idiot who only came here to get away from some distant dust bowl.

[tailspinzz]

I always show this to my kids when they ask if the US really landed people on the moon.

[atlante2020]

...and there goes the theory of the moon hoax down the toillet

[BennyTocamelo]

You just gotta love science!

[monkynutzuk]

someone on the space station has to have had a wank (im seriouse) i wonder who was the first life form from the planet earth to have a wank in space?????????????????????????­???

[bengacris]

hahahahaha cmon :P

[monkynutzuk]

@bengacris

seriouse! zero g bash!!! :P

[akaredcrossbow]

But the 190-200lb man floats as he walks gmab

[JarfJam]

He doesn't float. The moon has a much smaller gravitation pull.

The hammer would fall faster on the Earth despite the air resistance because of the greater gravity.

[trevoroliverharris]

True, but so would the feather. The fact is all objects in like gravity fields fall at the same rate when you ignore air resistance. Imagine a led ball and a styrofoam ball of the same size. Geometrically similar objects have the same air resistance. Drop them from the same height and they will land at the same time.

[squidinkUK]

These movies never ceases to amaze! This film shows such a simple exercise but illustrates Galileo's hypothesis perfectly.

[CT2507]

@squidinkUK illustrates how gullible people are perfectly.

[2mnyshp]

was the feather coated with something? i know that there isn't an actual temperature because of the lacking air but if the sun hits the feather shouldn't the heat destroy it?

[SoggyHobNob]

how hot is the direct exposure on the moon?

[rochelimit55555]

It does reaches 100 centrigree during daytime, but with no air and no atmospheric pressure . . .

[halby720]

how could it burn without oxigen?

[bengacris]

hahaha right

[onetwonine2]

Awesome gravity experiment. WIth no air resistance on the falcon feather it falls just as quickly as the hammer.

[CT2507]

@onetwonine2 hahaha... and u believed it?! :)
