So wonder if this works for bodies? As a military parachutist we often jumped at around 180 meters …(idea being to reduce chance of being shot at- I did a search on military jumps just to check if I had forgotten and it said sometimes actually 150 meters!}) according to this rule, that gives us less that 6 seconds before we hit the ground. It takes 3 seconds for the parachute to open which we count out before we check our canopy. If there’s no parachute there I would have 3 seconds to register that fact to pull my reserve which by the time it deploys I guess I would already have said hello to the floor!
I actually had one on this Day but the ground was to rocky and i couldnt measure it . My rangerfinder needs a flaat surface to get a Laser responce . But im thinking about making another Video , with water underneath . Hope it works with water though
I don't understand. If a second is 5m, then 3 seconds is 3 x 5 = 15m. OK, so far so good. But why multiply by 5 again to get 45m? Similarly, 4 seconds is 4 x 5m = 20m, not 80m?
Distance = .5 * Gravity * time^2. Gravity on earth is 9.8m/(s^2). 9.8 * .5 (or 9.8 divided by 2) is 4.9 which is approximately 5. So take your time in seconds, multiply it by itself (square it), then multiply that by 5. T*T*5 = Distance.
Thanks! I will use this when I’m outside again. Love your videos 👍🏻
💪🍺

I think a read once that a freefall from 200 meters is around 6-7 seconds so you might be wright
Moin Albert ☕️👋 egal ob Entfernung oder Tiefe bestimmen, du erklärst das optimal! Gruß und 👉 👍 👈 Patrick
Moin ..Danke 💪. Guten Rutsch wünsche ich 🚀🍺
You should do another with a laser rangefinder to compare

Thanks for the trick! That looks like an old quarry or mine?
Yes ,its a quarry , but its not in use anymore since 2017 . Great Place if you like to look for some Minerals 🔨
man lernt nie aus... thankx
Jeden Tag was neues und man bleibt Fit 💪
That's not how gravity works. It's geometric, not arithmetic. Well, up until terminal velocity...
I think you think to Complex here .
I can't wait to try this in NYC next month. Can I use bricks or cinder blocks?
Yes , but make shure there is no one underneeth you
@@yyyalbert well, that's no fun.

Hey , every Second the Rock speeds up .
1 sec x 5
2 sec x 10
3 sec x 15
3 sec. = around 45 m... 4 sec is 80 m... 4x5x4 ... multiply the meters with the seconds... 20m x 4... at 1:30 he declares
Distance = .5 * Gravity * time^2.
Gravity on earth is 9.8m/(s^2).
9.8 * .5 (or 9.8 divided by 2) is 4.9 which is approximately 5.
So take your time in seconds, multiply it by itself (square it), then multiply that by 5.
T*T*5 = Distance.
Perfect 💪
yeah that was probably the worst explanation of anything i've heard in some time
You know we all take math in school. You could just give us the formula.
I did 😁
Please don’t encourage people to throw rocks off of cliffs. You don’t know what/who is down there.
I encourage people to go outside and learn , but you are wright i should have told it in the beginnig and not only show it in the first 15 seconds
