    • @Kevin Luo Uub

    • Hi

    • @Kevin Luo No, pens don't. Pens also don't work upside down. There is a special space pen that can be used in zero g. Watch What's Inside's vid

    • I have a question Mark Rober: Ok, so if I 1v1 someone and I beat them 30-0 how much better am I then them, cause im not like 30 times, or infinitely times better because that would still be zero. Am I just “better” or is there an explanation to it?

    • Mark Rober I’m a HUGE FAN OF YOU when can you make some videos?

  • who else here from an actual science class

  • Funny I should come across this. I was just wondering this question myself earlier today. The best I could come up with was to spin the astronaut and measure how much energy it takes to spin them up to a certain amount of angular momentum. Then you could work out from the energy required and figure out the mass of the object, or person. Of course this is wildly impractical and inelegant. So I'm sure they've got something better. In retrospect, I'm sure doing the whole thing linearly instead of spinning the astronaut would work, as well. Get something to push them, then measure their speed and how much energy the device put into pushing them and you should get a good idea of how much mass you just moved.

  • I mostly learn things from youtube than school

  • .... Um, inertia IS newton's first law. You're literally talking about the same thing. "Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia." - NASA "in·er·tia 1. a tendency to do nothing or to remain unchanged. 2. (Physics) a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force."

  • I never thought I would actually see someone who worked for NASA play on a baby playground while they’re still in adult

  • Imagine just be walking in a park and then seeing An adult playing in a playground by himself

  • Thank you so much.

  • Ha ha we pulled off the table cloth he said by the way do you not try this at home but try this at home

  • An educational video by a NASA-level engineer, in 2020, and we still have video interlacing. Also why does he sound like a guy about 3-4 drinks in at a party?

  • I think I got it I’m on clue 2. The astronaut will stand on something that pushes them to a scale that will sense the momentum

  • I wish he was my real techer😃

  • What is it called when you lift 5 pounds 100 times instead of 500 pounds once?

  • Thanks for the shout out from a female scientist. :-) Oh,and I've been having fun quizzing my engineer husband to see if he knows the answer to your questions before he sees the video.

  • Bro I’m a boy

  • @6:34 is that why you see some videos of big ships crashing into ports? Where the captain likely underestimated the distance needed to slow down e.g. instead of stopping at 15 miles they stopped at 10miles

  • All science teachers could never

  • im asking my self why i am watching this in the middle of our bible class i also dont know cause i dont really know

  • I thought it was as simple as inertia and math

  • me sees a cool title watches the whole vid until u realized that the answer is just the horse at the playground

  • Mark: just reflect the hammer out of the way easy. Me: sure mark.

  • Hi

  • Hi

  • Woman runs around neighborhood Sees Mark Rober on a five year old toy

  • This is fantastic and perfect for my 8th grade science unit on Mass/Weight/Gravity! Thank you!

  • Mark: I do online classes for students Also Mark: do not do this with YOUR WIFE’S plates

  • You should try skate boarding but learning like sciencey and stuff

  • Mark would be the best teacher out there!

  • is there friction in space??? pls reply :(

  • Please do More of these

  • Tip for ketchup bottles. Open the lid and squeeze the bottle a little and close it back up while still squeezing so that the pressure in the bottle is lower than atmospheric. And now when you open the lid after moving the ketchup to the opening, it will not spew out everywhere . Also, I sling the bottle while holding the base and use centrifugal force instead of acceleration and deceleration lol

  • So the people who work for NASA ... that killed people .. anyhow .... now do this ... ok ))) now the space shuttle’s make sense!! ... oh not

  • Drugs ... ?

  • Welcome back to an adult child ...

  • thank god this si here i am having a hard time learning newtons law

  • Anyone here from a comment from Daily Dose of Internet

  • This is Grade 8 highschool physics right here

  • 1m IQ organic human and hello, I'm fellow organic human

  • These are wonderful, I don't think they need to be Live to be honest! So you can take your time to make them in a way that is convenient, because these classes are excellent (I have a degree in aero engineering and I still find them engaging 😄)

  • Me quiting science to learn more from this

  • That ball didn't stay where it is come on mark

  • not your best work homie

  • Can confirm, mark rover would be an absolutely amazing physics teacher. Any school would be lucky to have him

  • ''mass is what matters'' the physics dads snicker in the background

  • 5:56 my guess is by being pushed or somethins similar

  • *This dude is better at explaining than all my teachers, combined*

  • Wait so if we went to Mars I can finally be able to dunk on 10 feet?

  • I am 13 and you teach me more than i need to know

  • You are good man.. Keep it up

  • This is what we are learning now so I showed my teacher

  • As a physics teacher, I love these videos and would love to use them in my classes, but the auto-captions that they currently have do not meet ADA standards for my Deaf and Hard of Hearing students. ISchats makes it pretty easy to go through and edit the captions for grammar and accuracy (ie adding punctuation and correcting any words that did not transcribe properly). I know some of your videos have full and proper captions, would love to see that for this video as well!

  • 20:13 Oh my god Mark Rober Mars Rover Is it mind blowing or what? 😱

  • Rober's First Law of Motion : "Objects are lazy" 😂

  • I'm not even interested in science but I've always been following his experimental videos and istg if he's the teacher for my science class I'd understand better the way he explains things and all that

  • he knows me

  • Please make some more

  • Imagine what that person jogging with their dog at the playground thought of Mark on the spring thing

  • can you become my high school physics teacher. pls

  • Video idea here: DemolitionRanch on ISchats has 2 videos on shooting a bullet threw a curved pipe and it works, maybe try to partner with him, honestly if your able to get ahold him he would do it any day he could. Then you give us the science on it and that video would be amazing. You could even try to partner with the slow mo guys and do clear pipes to watch the bullet travel.

  • Mark makes science fun WITCHCRAFT

  • Please ╔═╦╗╔╦╗╔═╦═╦╦╦╦╗╔═╗ ║╚╣║║║╚╣╚╣╔╣╔╣║╚╣═╣ ╠╗║╚╝║║╠╗║╚╣║║║║║═╣ ╚═╩══╩═╩═╩═╩╝╚╩═╩═╝ To Mark Rober

  • I wish my physics teacher taught me like this

  • teacher who all im seeing is mark rober

  • Attach a scale to the wall and launch yourself feetfirst with an acceleration of 9.81m/s at the scale at 90 degrees to the scale? Then take a measurement of the largest force that was reached...?

  • Mark simping

  • I imagined an astronaut being slammed back and fourth by ping pong rackets with a weighing scale taped to them

  • Imagine running by a random Man riding a sea horse in the Playground lol

  • Could you do a video on the theragun? I was doing some research and I believe it is a simple percussion motor and companies are up selling their massage devices when it should be less than 100 dollars.

  • Make a rail gun plz

  • 1Q 1

  • When the only online lecture you attend is Mark Rober's.

  • OK Markie - I am a 65 yr old "girl" who loooooooooves your channel! How about that!??

  • Well you are the best today is my test this cleared my all doubt and I am from India 🤓

  • I feel he should not have said that the middle east is "less progressive" womens right wise. Because in islam (main religion of middle east) women are equal to men. Just they are not supposed to be "too close" . but it is fine that you thought that

  • Mark: objects are lazy Machines made of objects: am I a joke to you

  • 4:24 I never knew that they had tomato ketchup during Newton's time...

  • The woman in the back jogging be like What is wrong with today’s generation 🤦‍♀️

  • can someone please ask the caribiner to stop moving 😂

  • (Guess before watching it) They use bands(out of rubber probably) that apply 1 g of force to them towards the scale?

  • Bad astronauts get put in the astronaut shaker

  • ❤️❤️❤️❤️❤️❤️

  • Are you reading cards.

  • 13:17 imagine what that person is thinking

  • Bruh I would rather be taught by mark rober than my science teacher

  • Isn't ketchup a non Newtonian fluid??

    • I personally don’t think so but it’s very likely

  • Can’t wait for new video! Hope it is good because you talking more than 1month to post hehe!

  • I would go to your class like everyday haha! Keep up the good work! Keep going!

  • Kudos and high marks for the person commenting on the previous video for posting about the Mark Rober / Mars rover audio similarity. Perfect, and perfectly apropos. Am often good at those things, but missed that one altogether. Hats off!

  • can you prove earth is not flat?

  • The only thing I got was MOUSEFART MOTORS!!!!!🤣🤣🤣🤣

  • this is amazing just like ur other videos

  • Mark: you're basically Issac Newton! Me: *happiness noises*

  • Marks least viewed video I think

  • Easy on the drugs bro

  • Could buoyancy and density come up with the same results?

  • Uh oh 2:20

  • So cool seeing you talk on Science channel about the SpaceX launch 👍

  • Ho else saw him on tv for the launch

  • 11:15. Me. Oh! They lay in a bathtub and see how much water they displace!

  • Molokai
