What Happens When You Jump in an Airplane? 

Unless smoking weed

Don't worry. I'm not going to jump on it, I'm going to jump in it!

You jump in an airplane, you get duct taped to your seat.

Why did they name it Boeing then??

Very true. I lived on a Guided Missile Cruiser for almost 4 years and when the waves were 20-40 feet and when we timed it right, while the ship was about to go down, we could jump (relatively speaking) around 5+ feet straight up the ladder. Also, we learned very quickly how and when to slide down the ladder. Thanks for the great video. You guys make a great team!

What if there is No air in the airplane ? What if there is No air, and you are in a moving boat? What if No air, and your boat is inverted ? (Like a bowel shape) What if your inverted boat is a spaceship ? In which case will the vessel move separate from you?

I concur!

😂 Yes please !

What if there is No air in the plane? What if the plane has no roof and no air. What if the plane is inverted (like a bowel); has no air; and no floor and is in space. You are inside that plane. If the plane starts moving forward, will you also move or not move?

I bet you forgot about physics 7 months after

@@user-wj8kv2rv4u I haven't cause i subscribe to the channel so i see new exciting videos all the time. not sure why you are hating with your sad sorry self

Superb example. Thank you!

@@AndrewBlacker-wr2ve Thank you!!

Turbulence, I hit my head and fell in the aisle

With the train/ball example, how come the smoke from the train trails back behind the train ? Does the ball thing only work with a model, indoors, where there is little wind resistance ?

Gold medalist 😅

It's called a wing man.

You mean for a scientist hes pretty funny 😂

Could not agree less. He's insufferable and ruins most of these videos.

I hate that ride. 😂

I saw something similar on that ride

On a ride called Drop Zone, a friend an I would hold a penny between our thumb and index fingers. Separate the fingers at the moment of the drop, and the pennies would fall at the same rate, appearing to hover over our laps. Fun!

There’s a good sequence near the beginning of the film Behind Enemy Lines, where the deck crew launches a football with the ship’s catapult, and as the ball is still falling the ship catches up with it.

Not sure if they do it anymore, but back in the 80s, Six Flags Great Adventure in NJ would hold a Physics Day where students could go to the theme park and do experiments all day on the rides. They had one of those Free Fall rides, and dropping a penny as the ride dropped you straight down was one of the experiments. You could also ride the roller coasters and map out how many Gs you were pulling at various times on the ride. Having the park open only to a bunch of high school physics students and teachers from the area was a treat.

The pilots tell you when there's a turbulence zone ahead.

@@louisrobitaille5810That is not 100%. Sometimes there is a burst of turbulence seemingly from nowhere. I was on a flight to Miami when that happened while people were being served snacks. Food was everywhere, and some people got injured.

*all up on you. It is more effective when you use the word all with up on you.

​@@louisrobitaille5810Maybe a week or two after this video (and your comment) coincidentally, there was a really awful case of turbulence that the pilots didn't foresee at all, and a lot of people without seatbelts got really hurt. It definitely changed my mind about keeping my seat belt fastened. It doesn't have to be uncomfortably tight or anything, but just enough to ensure I don't bash my skull into the ceiling. Yikes!

lesson for the globers. there is no earth

On a real train at train speeds, definitely. This is a model train going at its slow pace inside a classroom where there would be very minimal air friction. Then, if the ball isn't tossed very high, it very well should fall back in the stack.

Also assuming the model train is running at a perfectly constant speed along a perfectly level and straight track with a perfectly vertical stack.

Yeah that and will jumping save you in a falling elevator if you jump just before it hits bottom.

No such thing as Zero-G, you are always subject to Earth's gravitational pull.

@@tettazwo9865 I know that. Those parabolic flights (reduced-gravity flights) are also called Zero-G flights, it's a brand name. It's pseudo-weightlessness or near-weightlessness, that's obvious and also advertised as such.

@@SlickArmorNo, jumping will not save you for at least two reasons: 1. The reference frame, your jump is relative to the moving cabin. 2. A human being wouldn't be able to exert enough force to counteract the fall. The cabin will keep experiencing gravitational pull while you're still inside independent of your jump, so you'll get crushed together with the cabin - your upward motion inside of the cabin won't stop that from happening.

@@jewersp that makes sense. And with that in mind I don't think there would be any upward motion inside that box. Like you say it would take incredible strength to over come the speed and gravitational forces.

Don't. It is dangerous

@@CarlosAlberto-vg3qy exactly!

My best jumping story, When I was in the Army, I was sent to a armor unit working with the mechanics. My first day there, they asked me to test the shocks on a tank by jumping up and down on it. I already knew what was going to happen, nothing, so I did it anyway to play along and make friends.

why ? @@CarlosAlberto-vg3qy

Exactly the point I was about to make!

Was going to write this. Unless the train is in a vacuum there is no way that golf ball is landing back in the same spot.

It was a model train used and an exact speed was never stated for the train. Also, a golf ball is designed to have little to no wind resistance, if I am not mistaken, so the wind resistance may be negligible for the model train experiment.

Sorry, I just saw this. I made a similar comment.

@@jefflane8272​​⁠The speed of the train is of no consequence. As long as the ball moves from a place of zero wind resistance, to a place with wind resistance (assuming the speed of train is static), then the ball will not fall back to its original point. All objects moving through air will encounter resistance.

If you jump while on top a plane while moving , you make a beautiful arc to the ground is my guess.

@@garethbates5044😂😂😂😂😂👍

I second this. Unless we are talking absolute vacuum.

He was talking about a toy train not moving fast enough for air resistance to affect the ball enough to miss the funnel it came from.

Most of these explaining also why the tray table needs to be stowed.

It also creates more space for the rear passengers to disembark quickly in an emergency

Otherwise the flight attentants need to put all the seats in upright positions themselves. This surely is the only reason 😂

I don't know about that bit about sliding under the seat belt... that implies that there's room for you to slide forward into, where your knees are already quite possibly touching the seat in front, depending on how big you are. If the seat belt is properly adjusted that minor angle won't make a difference, you'll still buckle (no pun intended) forward.

This isn’t gravitron, nobody chooses to sit vertical or upside down. Especially not for hours and hours and hours. I suppose you enjoy all the blood going to your head for hours on end? The seats are upright because it’s how they should be. Fighter pilots can fly upside down, but guess what? They sit upright... whoaaaaa O.o

We did the same on our school bus when I was young. Behind the back wheels, on a bumpy road, timing the jump to get more height & stay airborne longer. Fun times.

and air resistance

I just asked a similar question. I would hate to think that StarTalk got such a simple animated physics proposition wrong. But I think they might have, in this instance. 😮

It has momentum though

It's still got it's forward momentum and a golf is reasonably heavy for its size. The small amount of time it was exposed would only have a negligible effect.

Yes! If it goes high enough, the friction of the air would make it land behind the starting point!

3:45

Yes you would, same as deceleration!

This is a better question.

Well it's using the air to hover and the air inside the plane is also going 500mph

This is what I have been wondering. While the air in the plane is moving along with the plane at the same speed, it is also a fluid, and the object has an effect on it imposed by the air. What about if you pumped the air out and made it into a vacuum? This naturally would not work with a drone. I guess if you took this experiment into outer space and performed it, as long as there were no other forces acting on the system, I think an object suspended in the middle of the cabin would probably stay there not moving at all. This is of course with the object being relative to the cabin even if the ship was moving along at any rate of speed. As long as there are no changes to the system the object could stay in that position indefinitely? Laws of inertia? You certainly have to be careful in the phrasing and specifics of such ideas as things can get misinterpreted / misunderstood. I think this is interesting to think about.

I'm afraid that's not a good compliment, jk 😂

@@prakash_77Wdym? Lectures aren't always boring 😐.

Essentially, it just comes down to the medium in which its being depicted. A flat map, is just that, flat, it doesn't take into account the earths curvature, which is why Africa is generally much larger (or smaller, I forget which way round it is specifically) on a 2d map, nor does it account for the earths rotation or that the planets axis is skewed. If you were to take that flat map and stretch it around a globe, introducing the earths curvature to the route, add the earths own momentum, and tilt it a bit (what is it, 22 degrees?), the turns on the flat map, should, start to resemble more of a straight line. The sharp turns (30 degrees or so) that you would see on the in flight map, at least 15+ yrs ago (its been awhile since I've been abroad), I believe is just to do with when the planes location was last updated via the gps sats. If the plane passed into a new longitudinal "zone" in between gps updates, the 2nd update in the new zone could make the plane appear to of turned, I believe. That last part I could just be making up but it makes sense to me. That being said, many flight paths do have turns in them. Slight (5 degree) deviations, to allow for a variety of things ranging from weather to traffic but I know that wasn't what you were referring to, I just felt it worth adding :)

That happens to me all the time. I hate it when that happens.

i jumped up during lunch, landed in nyc grabbed a slice jumped again now i’m in the ocean…😢

In Virginia, your not going 1000 mph. That speed is at the equator, not north/south latitude of it.

I knew there was a scientific flaw in his example, but I couldn't pinpoint it. @@MrT------5743

​@@MrT------5743thats the issue with rpm, on a circle width, diameter. The metre is a human label unit, and distance will vary with rotation amount in the unit time of a second, which again a second length is designed by human labelling. This is why we use the unit horse power and measure in a average force of one horse. As you decrease the diameter of a circle, the shaft is still doing the same rpm, but the circumfance of the circle will be doing less distance, but will have more torque than a larger circumfrance at the same rpm. So in science we have to set a standard of distance when measuring say one metre for sound loudness, so we can compare to other experiements like for like, ie a reference standard. All measurements are a made up length by humans of what the human enviroment is, ie night and day. So on other planets 1Hz, one rotation, may not be the same length of a second in time between the planets, and water due to gravity differences may not weigh the same in Kilos ie 1m x 1m x 1m cube of water = 1 metric ton, which is the reference point for weighing other elements.

It’s so that reclined seats don’t make it hard for you to get up out of your seat. Try getting up when the person in front is in full recline, at least in economy.

He’s got my vote

Neil's a liberal no no no

You're the reason the 'vader was always broken.

Yes, air resistance would affect the lateral motion. Usually you lean into physics though, so air resistance (in every way) isn't taken into account in order to prove the underlying point. Adding in fluid dynamics (since air is a fluid) can be a tough problem to solve because you'll need a cross section of the ball, a coefficient of friction, a density and makeup of the gases in the air, specific velocities of the train and possibly wind direction, and other variables in order to find an answer close enough to the expected solution.
