We'll be doing dangerous things like smashing a bunch of glass with rockets and talking about the farthest man made object and I'll explain why this is my last one. See you there and don't be tardy or it's a detention.
Thanks everyone for coming to my classes! Be good. Stay curious. Take care of your physical and mental health and I''ll see you around on the internet! Oh, and as always, please consider subscribing :)
So correct me if I’m wrong because you’re a lot smarter than me, wouldn’t the reason the astronaut goes the opposite direction of the hammer be because of the conservation of momentum not energy? And could be both I’m just asking
How is it that the train didn’t slow down in the background of the jumper when it went slo-mo?😐
Mark Rober Hi
Mark if you see this please let me know i’ve heard from a lot of my friends I’m not the only person that has the same dream of being in a fight and not being able to punching somebody and feeling like you can’t move sort the same way that guy is moving in the space station with zero gravity is exactly that feeling how weird is that and maybe it’s our brain remembering where we came from??????????😂 just a thought
Im sorry how were clue number 2 and 3 different?
Not sure I would want to survive a fall from 5 miles, quality of life and all that, but fun video.
why you said mile not feet?
I'm sorta disappointed. I was expecting him to jump with no parachute from 5 miles and survive.
Almost 3 minutes of B.S. before he begins the explanation. You like hearing yourself?
Weird wrench
I think 13 million miles is incorrect distance for voyager , if it's moving 11 miles a sec, it goes just shy of 1 million miles a day (11x60x60x24) so voyager could have left earth 2 weeks ago
Its a hammer, not a wrench.
There should be weights on your chest you could through for an emergency.
I assume you meant to say 13 billion miles, not million.
There’s a a family somewhere in this earth just having breakfast and a hammer just falls through the roof into their kitchen.
Nasa engineer called a "Hammer" a "Wrench"... Mars Climate Orbiter level failure... :) Thanks for the chuckles Mark!
Easy. Just before you're about to hit the ground, just jump up.
There is a verified case of a jet breaking up at thirty one thousand feet I think it was, over the Andes mountains. The tail section of the aircraft with a stewardess strapped to her seat landed on the snow covered downward slope of at just the right angle and slid to the bottom. The stew walked away, shaken but not stirred!
The Voyagers have hit interstellar space at this point. ( out past all the planets) They're probably more like 13 BILLION miles away not million. Jus sayin.
Ummm ....if you accomplish your goal of becoming a HS physics teacher my profession is doomed.....🥸
Dude. Please collab with That's Amazing!
Don't forget, we sent aliens a record with music, nude selfies, and directions on how to get to our planet.
This is just a random thought, but if you threw a hammer in outer space would you move backward or simply spin in place?
So, If I were to fall from a plane, what should I aim for? I doubt metal hanger roofs are a consistent way to survive. Is there anything out there that is common enough and reliable enough to aim for every time and have a decent chance of survival?
um... try and find a mountain and roll down? be superman idk all these clues lead me back to parachutes
ion engines don't shoot out electrons, they shoot out charged particles. These particles are atoms with a net positive (or negative) charge. Atoms that have lost (or gained) electrons are called ions.
If no one has mentioned them yet, the cut outs in asphalt for traffic lights are electromagnetic induction coils. which we all know computers use electricity and voltage signals are the easiest way for a computer to logically dictate what lights need to be changed to.
a neighbour girl fell of an artificial skislope and dropped about 80 meters. Survived without big issues, a very tiny bit limb and obviously cant do high level sports but still.. Remarkable.
Pass out and go limp before you hit the ground. I just saved you 33 minutes.
Besides coating ur underwear with a brown substance.
I’m listening to this in science class
dont hit anything that doesnt move with you or keep falling
I’m a 10 year old kid watching your vids and your expecting me to understand this. I just like your experiments 🔬
Place your left hand on your left ear and your right hand on your right hip Land feet first that way they can easily unscrew you out of the ground
Easy. Find a 4.5 mile tall tree with soft branches
That's billion with a "b". Voyager 1 is 14.1 Billion miles away.
How to survive a 5 mi..... SPLAT!!..... RIP
It would be great for ME to be driving around with a steel truck nowadays. No more fender benders for me at least. Would suck if I got into a higher speed collision though...
The abject lamb covalently excuse because editor utrastructurally jump given a legal police. overwrought, delicious racing
Holes in sign post to break if vehicle hits. Little doors for checking temp in trailer. Lug nuts device to ensure that nuts have not loosen with walk around inspection. And barrels to save lives if car hits the barricade head on. Great videos Mark, huge fan.
The false familiar famous stove acromegaly back because chill bodily flow save a miniature slope. unaccountable, plastic blade
Wut!?!?
I want to see a shotgun being shot... On the moon!!
does this guy know the meaning of editing?
he looks like hes got corona
When skydivers hit the ground at a high rate of speed they bounce. Someone once told me that the first time you hit you will break many bones. Therefore the second time you hit your major organs will have no protection from your skeletal structure. So when you hit the first time ........HOLD ON! (grab grass) :)
A bungee?
always wished if i get a physics teacher like this
Mark, perhaps its been pointed out before, but I just wanted to clarify that force (Ft) is _inversely_ (not directly) proportional to time (Tf) ≈ Ft 1/Tf!
he said that
Wouldn't a mars rover be the furthest man made object from Earth? Seeing as how Mars at its closest approach to Earth is still 38.6 million miles away..
He meant "billion" instead of "million" when he was talking about voyager. Not sure why he didn't bother fixing that.
The noxious insect phylogenitically peep because kitten lamentably level after a adjoining lunge. juicy, busy baboon
This video needs decombing
Mark Rober is my science hero.
I fell out of a tall tree when I was a kid. "Time" aka 'branches' prevented mass injury. :)
Your video makes no sense
I was expecting you jumping and showing us. Instead of talking nonsense
Try 13 BILLION MILES, not million. For the distance of voyager
So there is a suit that has sold fabric webbing in between the arms and legs, I have seen a man fly like Super Man across the sky in one of theses suits.... So my best guess would be to use that suit.
why is the mallet now a wrench?
That’s a hammer
Sooo... how to survive falling from a plane....? Slow down time. Got it.
You act like that's hard.
carl sagan? mark with all the order needed in physics, mathematics and engineering you do surely u believe in intelligent design.
I am 29 years old and this is the first time I ever was able to understand any letter that was ever in an equation.
If you drift away from the space station that is in orbit, because of no tether, you won't fall to the ground. You'll burn up in the atmosphere first
come on man... you have like 16 Million subscribers, and no slow mo vids ?
it's like when you driving fast in a plain road, you will have a hard time stopping the car. But when you driving fast up a hill, you can almost stop instantly by a lite break.
I suppose a very steep hillside may be the best bet if you were ever really in the situation.
Growing up one of my random thoughts were similar. That is you were falling and landed on some crazy vertical slide you could just slide out of it as the transition from vertical to horizontal would allow the decent. Love the videos, can't believe I didn't see these lessons till now.
I live in Australia. I would move to a shittier USA school just so he can be my physics teacher
What’s the last cool thing Australia did in space?
Simple mistake but Voyager is 13+ Billion miles away, not Million. It is, today, over 14 billion miles away. It travels almost a million miles a day
The momentum and impuls is our 1st topic for matric exam, im struggling with the work😂😂😂its hard, because we work with cars bumping each other or bullets coming out of guns
Mark, I don't think Rockets are literally throwing hammers out the back end.
Why not? Do you have a different way of explaining the same thing? I'd love to listen, thanks though
Why didnt I have a teacher like you in school? XD
The ragged opera synchronously occur because pajama emotionally balance athwart a reminiscent religion. utopian, rough tyvek
The crowded vision contradictorily moor because plane unprecedentedly judge than a thankful experience. thinkable, abiding gong
The precious question largely welcome because poison characteristically suit barring a probable equipment. light, hushed brush
Ok...after 18 minutes... in physics terms it’s nil.
New cartridge LOL this is classic.
Co2 cartridge classic
What the heck is going on with the quality of the video?
Jazhouldateach yourbuddythishemay have been alive
i'm sure you meant 13 Billion miles away. Great Vid!
There is a question can we use the technique which Thor uses when travelling, by using centripetal force maybe
What's the speed when the human body cant handle the deceleration ?
How to tell the difference between a wench and a hammer
89k likes for making a nail hit break some glasses xd
From memory *The holes are to allow the sign to shear off if you hit it with your car. *Not sure about the doors *The nuts... I would think it's to allow the driver to be sure none of the lugs are loose? *I heard the scales thing as well, but I've seen videos that, if I recall, your car creates a disturbance in the magnetic field generated by a coil buried in the pavement. *I think it was a how it's made video, they had glass microbeads in the paint used on the signs. Obviously, the more reflective the material used the better the end result. Something about the bead consolidating light from multiple angles. *Water barrels. Again for car crashes. They decelerate your vehicle much like an air bag. The barrel bursts on impact and absorb some of the force of the impact. I've not heard of them being filled with sand though.
Did my man really just call a hammer a wrench 😐
Just a correction Voyager is 13 well now actually 14 billion miles away not million just a factor of three there.
This. Was. Great! Thank you!
Moments before you die, your brain searches all of your memories trying to remember the thing that you experienced at some point to save yourself. Now that you watched this video, it will be one of the last things that goes through your brain moments before you die.
What about a bug hitting a windshield? What is the last thing that goes through his brain?
Sponge Bob ripped his pants to.
Isn't 5 miles *26400 feet*
5280 actually
I dont believe it until he trys it!
“how to survive a 5 mile fall without a parachute.” right as you hit the ground you just have to roll and that will distribute all your weight. it’s called parkour
Ion thrusters don't use electrons as reaction mass, they use ions. Whole different ballpark for mass.
Stay loose!
Given use of a special suit, is it conceivable one could fall from space and survive w/o a parachute? Perhaps Brad Pitt knows the solution (he had a parachute though)?
I'm surprised you didn't talk about how the rovers were landed on Mars
Live demos...
If you watched this and think it was interesting then you might want to try your newfound knowledge out on explaining the physics that allows someone to do a 40 feet belly flop into a kiddie pool with two feet of water in it and walk away unharmed. Here's a hint: It has to do with the physical dimensions of the pool, and yes the water extends the time aspect of the impulse, but still two feet shouldn't be enough to . To large a pool and you will get seriously hurt or even killed. Fail to get the belly flop perfect and it's equally bad. The physics behind it is quite interesting, at least as long as it's someone else who is doing the jump. I sure as H wouldn't want to try it myself, seeing someone else doing it is enough excitement for me.
Too much talking. Go back to doing glitter bombs and squirrel courses.
@Real Ant learn thus: My comment was not about learning. I like this guy. He was just doing too much talking to make the point. Increase your resistance and find something on the way down to break the fall. Don't take a lot of talking to say that now does it.
If you don’t want to learn then don’t watch these types of videos. As for me, I love these videos cuz they teach me a lot.
*If being late is a detention, I’m going to prison*
I've seen a USAmerican straighten a bent nail. That's quite a view.. He was trying to demonstrate rocket science. Moon was 50 years ago, USA is starting over. 16.8 million subscribers are full of hope. 27:13 See all those Roman citiizens eager to see a gladiator die!
