I've done two tandems as can be seen on my TH-cam channel. Once you reach terminal velocity it just feels like you are floating rather than falling due to the air pressure on your body. It doesn't feel scary at all! In fact watch an experienced skydiver practising stable flight at an Indoor Skydiving centre and then realise that that is what a real free-fall feels like.
Terminal velocity is when you can fall no faster. In a tandem skydive the terminal velocity is about 120 mph. Yes solo skydivers can fall faster but that's because they do not use a tandem drogue chute and because they can fall in whatever position they choose so their Terminal Velocity can be up to 200 mph. Tandems use the drogue chutes for drag because you would not want to open the parachute at 200 mph! Anyway, whether you are a solo skydiver or a tandem skydive Terminal Velocity is whatever speed you reach and can fall no faster. With tandems that is about 120 mph as stated in the video and as stated to me by my Tandem Instructors. I have done three tandem skydives now all of which can be seen on my TH-cam channel. In one of my pre-jump interviews the cameraman states that I will be falling towards Earth at around 120 mph.
@The Great Bodhisattva Hachiman I keep telling you that once you get to 120 mph as a tandem then you are AT terminal velocity! You cannot fall any faster than that as a tandem. 120 mph IS terminal velocity for tandem skydivers.
@The Great Bodhisattva Hachiman If you are not going to believe what the video tells you and what I'm telling you then why are we having this conversation? Ok, you'll ll never reach terminal velocity. Is that you wanted me to say? Well that's it then. End of conversation.
I just got to jump by myself for the first time last week. Its strange, but as I was falling belly down, which is the slower position, I shifted my legs in and I "fell down" per say, quickly enough that I got scared for a second. Then I realized I'm already falling. lol. Its so strange to be falling in one position, then shift and fall again. Have you ever heard or thought of this concept? Maybe its one of those things that has to be felt.
I have 2 questions: 1)What is an estimation for the Surface Area of a man with height 1.80m(5.9feet) and weight 90kg(220.462 pounds) 2)Opening a parachute with Surface Area 30m^2(322 square feet) what is an estimation for the time in which the parachutist need to reach a steady velocity of about 5-8m/s(11-18mph)
I'm no scientist, but I'll try to reply: weight doesn't matter when calculating surface area, for example, we could both be 1.80 meters high and 1 wide, yet have different weight. So the surface area really matters on the person, and what they're wearing, try wingsuits! Canopies (parachutes) are measured in feet, 322 is really large (tandems use larger parachutes), while with that weight you would probably use a 280/290. Now the opening time usually depends on a lot of factors: how it's packed, in what position you open and how stable you are. Larger parachutes will take more time than smaller ones but the average time is 5 seconds. So imagine your're falling at 240 km/h, from the moment you deploy, it takes you 5 seconds to reach 5 m/s (18 km/h)! Hope this helped somewhat, bye!
The air resistance is not pushing back it's just more air is being pushed out of the way by your plunging body. The air is basically just in the way and you're falling body has to move more air out of the way in a faster process as your speed increases due to your density and mass, until you hit the ground. Hopefully you have a parachute.
Hey, this is the first video that i have seen from your channel. There is not much science to explain here and you did it interestingly. hope you succeed.
+Volt Pranks (VoltTV) That's fantastic, well done! Glad we helped out a little bit. Let us know if there's anything you'd like us to cover in a video for future tests & we'll see what we can do :-) - Ross
What a shame this is spoiled by talking about the "force of gravity". The force he is talking about is weight. There is no one "force of gravity". Every object has a huge number of forces of gravity acting upon it, one for each object in the Universe. It pains me that even people with Physics related degrees have forgotten this. If he wants to talk about the force of gravity caused by the Earth, give it its proper name - weight.
+KiddAndy17 Hitting water at 120mph would be a lot like hitting concrete at 120mph. If you've ever experienced a bad belly-flop into a pool, you'll know the power that the surface-tension of water can have on your body. - Ross
At-Bristol Science Centre Aha! Thanks. Maximum speed of a Porsche 911. I'd say, impacting at that speed could easily spoil one's day. PS: Is 193 kmh also the maximum velocity that the crazy Austrian had during his space jump? I believe air is a bit "thinner" at high altitudes ...

I haven't done individual jump but I feel like I could sense what you are talking about!
Why does this channel not have millions of subscribers. Literally my kinda tea here.

Thank you!!! finally I can teach these to my fellow classmates. My teacher is lazy that she relies on me to teach her students (including me).

Air resistance is indeed "pushing back". It's how drag works. It's a force.

Akhil Pai Thanks very much Akhil, we hope you keep watching :)
Thanks now I know what terminal velocity i bet you just helped me past my science test.
+Volt Pranks (VoltTV) We hope we helped out - let us know how you got on in your test :-)
- Ross
I was going for an A but i guess a B is good aswell thx again i might : have gotten way worst if i didnt watch this vid

I bet you loved it!
His hair is all fluffed up because of the plane🤣
I thought it was a sonic stage
Gotta go fast!
- Ross
Pretty sure the instructor isnt pulling at 3,500 ft with a tandem lol.
Who else got this for isolation homework?
Terminal Velocity is incorrect. The speed does not stop. The INCREASE in speed stops. Therefore it should be called Terminal Velocity Increase.
I still don't understand .
I only weigh 130 pounds. At terminal velocity, a fatter person would fall faster than me, I would slow down like a feather.
That depends, do you have the same surface area? You might end up hitting the ground at the same time: th-cam.com/video/bHsQ3V2AmEE/w-d-xo.html

I’m sonic
Who has physics rn from Sta

Would a human still be alive if crashing into water at terminal velocity?

+At-Bristol Science Centre -- How fast is 120mph?
The Kaiser
~193 kph
- Ross

Maximum speed of a Porsche 911.
I'd say, impacting at that speed could easily spoil one's day.

The Kaiser Felix Baumgartner reached a top speed of 844mph (or 1,358kph), breaking the speed of sound during his fall to Earth.
