Physics of Sky Diving

[hey99neul]

i really want to try this, but the idea of the parachute stuck and don't open terrifies me !!

[5001francis]

if parachute doesnt work ur fucked

[antion234]

im scared if a plane hits me xD

huuurrduurr who wudda thunk

[ken1266828]

her shoes were untied :O

[TheDikwaad]

"This doesn't mean she stopped falling..." No shit Cherlock!!!

[marcstylzzz]

@TheDikwaad sherlock*

[walshinstein]

a very helpful video

[thatguywithnoname]

That's a uk registration on the plane...

[Quagmirian]

Holy fucking fucking fuck I've just realised where this video was made.

[cannywf1]

@Quagmirian Where...??? Is it Brid...???

[Quagmirian]

@cannywf1 It fucking well fucking is.

[bterranova]

uhhhh, yeah, gravity is a force

[jokajem]

"when the parachute opens" Mmmmm...if it opens!

[improfision]

no i think 55 m/s is better!

[CrystalSoulLove88]

I am dreaming to do this soon soon.... I am curious how it feels like... flying.. the adrenaline .... ^^ The first time I have the chance I might do it... it looks like a lot of fun ^^

[fisheatsyourhead]

*sigh*

i hate science holework -.-

[Reuben961]

so i was hoping to get some tips on how to stay stable in freefall, but this vid is just stupid.... gravity pulls me down? :O ORLY? air resistance slows me down? :O

[JonskyGBR]

@Reuben961 ARCH!! : )

[Racersbase]

Well....I didn't know that gravity is affecting skydivers*lol*

Very educational xD

[stevenliemberg]

completing your flare is also a GREAT IDEA

[tombozz]

Hoihoi it9 :)

[TheMrsPhysics]

Excellent video describes the basics simply - good for GCSE revision. P.S. Gravity is not a force! Your weight is the force of your mass due to gravity.

[mikedamat]

@TheMrsPhysics

What are the four fundamental forces?

[GkuSS5isB]

@TheMrsPhysics what are you talking about? Gravity IS a force. Weight is the amount of gravtiontional pull on an object.

[muntoniG60]

lol, bitch needs to flare a bit more...

[idude09]

her shoe is undone lol

[DonMasakoni]

flare could be better

[MrIam1nsane]

....Did I really need to watch this video to understand this?

[Nnoshah]

yay =]

thanks !

[ROCKOUT29BR]

Sooooo, jumping without a parachute doesn't kill you, is the sudden stop!!! It makes so much sense now...thanks!!

[nutsbutdum]

@ROCKOUT29BR

But I wonder if velocity would keep increasing as you fall towards the earth until your body can't take it anymore.

I don't think there is anywhere you can jump from near the earth, so that g will be greater than 9,8 while you're traveling through the air.

[roomak1999]

wow. I understood that when I was 8y old. I hoped they will explain forces but this movie explain only that it is not good idea to jump without parachute.

[Snatcher1212]

This video is bull, the parachute NEVER has a greater force than gravity.

[basslinet]

@Snatcher1212 Yes it does,

The terminal velocity of the parachute is obviously lower than the terminal velocity of a free fall, therefore there must be a transitional force (air resistance) that allows you to slow down.

Acceleration due to gravity is a max of 9.8m/s^2,

Usually about 7 or 8 when you are free falling,

All the parachute does is provide a greater force in the direction opposite the fall to accelerate you slowly upwards until air resistance becomes balanced.

[Mctavish94]

@Snatcher1212 it is discovery channel....im pretty sure they know what their talking about and not bull shitting us

[ButterflyDragon9]

@Snatcher1212

Exactly, or she'd be floating and would never land.

[domyaska]

excellent! thank you !!!!!!!!!!

[Luap2020]

wow, what a terrible video... it says you land because of air resistance and then the "thumping force" of hitting the ground. that is stupid. The parachute takes on the shape of an airfoil and creates lift, just like the wing of an airplane but without any thrust. You land by pulling on both toggles, which changes the angle of the parachute thus increasing lift. If I felt a "great thumping counter-force" i would be in a great deal of pain.

[YouLudi]

@Luap2020

i think what they're trying to say is the ground force is so great that it stops the diver instantly, because they can't fall below or through the ground

[fenix159]

Wait a moment... landing with 5 m/s might be a better idea than with 55 m/s... but did the editors think just one second about what they said?! 5 m/s is 18 km/h! Hitting a solid target (like the ground) with 18 km/h isn't such a good idea!

[keeponwishin]

If you came in at 5 meters per second you wouldn't get enough lift when you flared. We come in more like 23 meters per second until were about 2 meters from the ground.

[angelfuree]

@keeponwishin

I'm pretty they're referring to the descent rate. A 23 m/s descent rate is 4500 feet/min. I'm pretty sure that's not what you meant because you'd end up a pancake if you tried flaring at 2 meters doing 4500 fpm. ;)

[archreachthrow]

oh, is that why we use parachute??

[Mctavish94]

no..its just there for looks

[basslinet]

@Mctavish94 Rofl!!!

[stenansikte]

nice landing lol

[TheSpackenhannes]

air resistance? that's not how that kind of parachute is working, idiots!

[carpetfactory]

heck... the "flare critics" are everywhere! She stood it up and walked the F... away.

blue skies to all, and to all a good night.

[t0winthiswar]

Looked like a terrible flare lol.

[krosfyah]

Yeah, she barely flared, that must have jarred!

[orbsytilds]

dah

[raween]

Loud and Clear

[charmcast3r]

thanks! this was a great help!
