If you want to learn about relative velocity and effects of jumping on a moving vehicle, talk to a sailor on a small warship like a destroyer. A trip out in heavy seas will teach anyone about all sorts of physics. My favourite is timing going up/down a ladder to match the waves, because if you jump off a ladder and the ship hits a trough, you could be in for a long fall, or if it gets a sudden crest, the deck will come at your face much faster than expected. But if you time it right, you can walk off a ladder right onto the deck up/down as required... if your timing is good.

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!

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.

This also applies to the vertical plane... having your seat belt on during cruise is always wise. If the aircraft suddenly drops and you're not wearing your seat belt, (perhaps because of environmental factors) you could hit the roof of the cabin; not because you have been thrown upwards, but because the aircraft is descending upon you.

Another excellent, entertaining, informative video gents. Always learning! Many years ago, I heard a great story about the US Ryder Cup team, which was travelling by Concorde to play in the UK. Apparently, one of the players (Brad Faxon I believe) holed a putt the length of the cabin. To those inside the plane, the ball had travelled the length of the cabin, whereas to observers outside the plane, the ball had actually travelled about 15 miles before going in the hole 😃

I was nervous trying it in my building's elevator given I live in one over a century old (rebuilt after the earthquake that destroyed San Francisco), but, since it's the only elevator I have access to, I gave it a shot... And ya, both up & down are cool sensations, thanks! 9:00

A human being wouldn't be able to exert enough force to counteract the fall.

Hey, big fan here.

If we had a strain running at 99.99% of the speed of light with another one inside it also at 99.99% of the speed of light. You get the picture, I'm sure 😊

Just have to mention that the golf ball, will suddenly go from zero wind resistance to the wind resistance somewhat equal to the train speed. So it will land behind it's original location.

When I was a kid and I and my friends were taking the bus, the bus in question used in Reykjavik had a standing area at the very back of the bus, behind the aft wheels. We often used that area to play in, even though there were available seats elsewhere on the bus, because we were jumping up every time the bus went over a speedbump. This of course catapulted us much higher then normally and was great fun!

I often wonder what would happen if while on a plane that is traveling at a constant speed you took out a mini drone and have it hover above a single spot for 30+ min. Would the drone eventually, ever so slowly, end up at the back of the plane? Does the time spent for the drone decoupled from the plane cause both the plane and air in the cabin to slowly move forward ahead leaving the drone behind?

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.

We need an explainer on plane routes. On a flat map you can have a route having turns but on a globe they travel in a straight line direction.

@BlueArsedGibbon

8 ай бұрын

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 :)

if you think about it, what you really meant is that in this accelerating reference frame, if you jump in such a way that all the force is normal force to the floor and no friction force, then you will indeed not land in the same spot, but if you jump in the direction that feels upwards/normal then you will land in the same spot, and the angle from the normal you will jump in will create a perfect little parabolic arc that lands you in the same spot on the floor form the outside observers perspective, pretty amazing stuff i think :).

​@@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.

They ask you to put your seat back up for taxi, takeoff, and landing, to give the person behind you enough space to get out of the plane in an emergency evacuation. That's also why seats in front of an emergency exit will not recline. It is also important to keep your seatbelt fastened during cruise, in case you encounter any clear-air turbulence. Without your seatbelt on, you could break your neck if you slam into the ceiling.

Very interesting indeed.

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.

I have asked mathy and sciency people for years a similar question.

Those that didn’t think I was nuts agreed with you. Interesting. Thank you!

That was the best train I`ve ever saw!

Many years ago I remember having a similar discussion when transporting a caged eagle in an Airforce C-130 Hercules I was flying at the time. Although there wasn't enough space for the eagle to get airborne, the loadmaster quipped that if he could get it to fly it could help with the takeoff... a lively - and humorous - argument ensued about the acceleration vectors and whether the mass of the bird should be included for [takeoff/cruise/landing] performance calculations should it take flight. In an attempt to resolve both these questions, it was suggested we operate de-pressurized with the ramp and door open. I think, even after many post-flight beers, we still did not resolve this fully.

Relative motion is mind blowing. What is the moment when do you become part of a moving reference frame?
