Hell yeah. I love space.
That was fun to watch, thank you.
I have been searching and searching for a good Newton 2lnd aw video, saw this and said (Ok ...let's try the astronaut maybe he'll be better at this) AND YES! finally right to my classroom. Thankssss
Hermosa demostración. Gracias
(Beautiful demonstration. Thanks)
Perfect demo video for my science class.
Is there any way to hide comments on these videos so I could share them with kids in my class?
Use a browser extension that blocks youtube comments, I know this works. You may also be able to turn off comments under youtube settings, but I'm not sure about that.
@@Kleinage nope imma save your kids
@@luishernandez-xq9lb wrong @, Louis
i think there is a website called safetube that can help (or something similarly named)
Send them...😊
I really wish i had seen them while studying in school
How is this gonna fix all the problems on Earth?! Just kidding, I love these, keep it up!
Thank you!
AWESOME Video!
love your work
So since the bungee is attached to the station, when it pushes the objects is the station's orbit being measurably affected by newton's third law?
Obviously it'd be undone when the object hits the far wall, but still seems like something interesting to look at.
It probably is affected but the mass of the ISS is almost 1 million lbs, traveling at over 17,000 mph, so the effect would be negligible.
Its not. Because at the end. The iss wall stop the object velocity. Basically same amount of force being released and received. Unless you aim at outside the station
Sorry for my bad english
The fidget spinner one at the start was cool😀
Please tell me that was an ironic statement-
you actual weirdo
That was very cool.
love it!
amazing
NASA is best
haha you said it buddy
thank you sir! I have a question.
would the velocity be constantly increasing?
Yes,coz its space,no air mean no way of stopping the object so it constantly gain velocity
Only during the application of the force. As soon as the elastic and the mass are apart, the mass mantains its speed constant because in the equation F=ma, F is equal to 0 and so must be a.
Be home safe cya Love ya takecare thankyou
Cool
This is so cool!
ew, a gacha ಠ_ಠ
Tegan Gallegos ew, a Gacha hater.
Sir Issac Never looked better.
AMAZINGGG
Physics test: “Without”applying the Energy from within you, choose an object of your choice, and apply only the Force or Net Force needed to push it away from you or pull it towards you. Please let me know if you’re able to. This is only a test. Thank you.
Uh oh, might there be a demonstration with less *impulsive* baggage? Working backwards from our Newtonian model, speed of the object after leaving the makeshift bow is its momentum divided by its mass. Its momentum is the accumulation of the force over time, impulse, while the bow is pushing against the object. The force is not constant over that event, and the total time is not constant for the different objects. The more massive objects received more impulse from the bow.
Consider new demo: For each object, have it eject, with a spring, a smaller mass that is constant for the different trials. There will still be some impulsive differences, since the smaller mass can't be insignificant compared to the trial mass. The only way we can eliminate such momentum factors would be to have a constant force over enough time to measure it and the acceleration. To use a noticeable change in velocity as a proxy for acceleration without a constant impulse...This is why we use fan carts at first, not bows. Can you invent an equivalent of the fan cart in the space station?
Just putting it out there, don't hurt me, there are 69,069 views.
not anymore
In my school in Canada we meet a real astronaut
Cool ! 😊
I want to know how an rc plane or drone would go in the iss.
Normal drones are designed to counteract gravity. On the ISS the drone would immediately crash into the ceiling (one of the walls).
hpekristiansen I know. I just want to see how cool it would be.
Will they accelerate forever in space if we apply force
No. Accelerate means increasing the speed. Obviously the speed wouldn't increase. It would stay constant and it would only slow down if there is something like little particles.
How do they upload videos on youtube in space?
They have satellite internet.
Grafight23 Wow, it might be incredibly fast though. Haha
Omg cool nice
1:54 ... THANOS SOUND
This is super skibidi
That's cool
Yeah, except Newton never said that. He said that the force impressed on the object is proportional to its change in motion. I really want to know who came up with F(net)=ma and why they didn't get credit!
Fnet=m*a is a modern interpretation of N's 2nd law, that enables us to learn it without first introducing momentum. N's 2nd law in its original form uses rate of change in momentum. The substance of the law is still the same, just expressed in a different form.
hum astronauts scientist kaise banau
NASA missions between 1968 and 1972 were premature and too advanced for the common people mind, but today is better than scifi movies.
how do they have wifi in space
Nah man it all about newtowns first law motion
Thank you so much. I'll show this video to my students!
PS.: eu preciso estudar inglês... lol
lol my teacher showed this video to my class
wait
Teacher!?!
@@rezon60fps25 😂
بشرى جيتك ته " go " وش صار في موضوعي .***
yep
I don't get it -- I thought the Law was that if you drop two things of different mass at the same time they will land together. But these examples show that objects of different weights fall at different speeds, and therefore land at different rates.
It still holds. Drop a penny and a brick at the same time and they will land at the same time.
No, if you drop a 1 pound weight and a 5 pound weight at the same time gravity pulls 5 times harder on the 5 pound weight. So their acceleration is the same and they hit the ground at the same time. In this experiment he is using equal force on different weight things so their velocity ends up being different.
That is sooo..... Coooo.....l 😮
This gets me wondering: doesn’t the restroom stink an insane amount?
No it doesn't.
Why do you have a big Japanese flag
in your spacecraft?
because Japan owns that spacecraft, or that part of the spacecraft.
my teacher is making me watch this
My school sent me this then gave me a 0 on my grade. there was nothing i had to do other than watch this video and yet i still get a 0.
If he posted the video in space it means in space they have internet I want to go to space my internet is not working 😂
Bruh I’m watching dis for school BTW
20 billion dollar annual budget. Thanks NASA!
when you were in lift off were you scared or happy?
Woooww
when ur here bcos u have to answer a gforms for science:
ขอบคุณมาก วิดีโอของคุณทำให้ฉันมีการบ้าน Thank you !!!!!

Kids get confused by the idea of force to accelerate a stationary body, inertia, versus acceleration due gravity, by two falling bodies, one light, one heavy. They both start to fall at the same time and reach the ground at the same time. Is the force different for each? The elastic used to propel the various objects here applied equal force for all, but it seems gravity is proportional to the object. Is each object interacting with the force in such s way as to make their acceleration equal?
The ether vortex theory suggests that that is exactly what happens. To test that theory has, as far as I know, yet to be performed. A very simple arrangement: dropping two spheres of unequal mass in vertical alignment, rather than side by side, in vacua. If the heavier body's ether efflux is altering the velocity of g so as to proportionately act on the body, is the smaller body's motion relative to the larger altered?
😂 Can see NASA calling you in space saying ASRO Bresnik , we need you to put back the mattress into the storage room. Thanks for an actual view of science in action. Hey, does blowing air out of your lungs give enough force to move you?.... 😂 does farting impart enough force to move a person??? 😂 😂 😂
pog
there are now 69 comments 🤣
despacito
who else is watching for school
POV: your here from class
POV: youre here because of science class
The earth is flat 4
Hello..... My aim is I became an👨🚀👨🚀 astronaut
why did they slow down the frames when he launched the chapstick and the little space ship? Ridiculous.
Big white bag filled with Helium.
Not quite sure what you mean but the video does not slow down.
So the person is filled with helium too?
STEM is elitist. Where are the welders and machinists??
This is misleading. It makes it look like a fixed force on varying mass creates a proportional velocity! The force varies in a complicated way from a maximum down to zero. This completely obscures the linear relationship between force and acceleration. Thumbs down.
Scheppersinstituut is de slechtse school 🤷
🤣You don't even read your own NASA propaganda. You are not in space! You are in Low Earth Orbit. The gravity there is 88% of earth's surface!
Anything above the karman line is considered space.
But they are still weightless because they orbit the earth at such high speed and are basically in free fall.
Green screen movie magic. One time just film a 360 degree turn while on space walk. nasa can't because it would reveal the fourth wall. 👎🏽
Still no commercial space travel. Maybe in another 50 years. Lol😂😂😂. No visible stars in space. Yeah no, they're really in space. Sandra Bullock is an astronot, I saw it on t.v. Lol😂😂😂
Jimmiejoe Sparky light pollution exists just like how it's hard to see the surrounding area when a car flashes their head lights at you, the closest we have to flying a plane to space is the U2 and that only goes to about 70k feet noe if you're talking about fully going into space (as in go to the moon or stars) it would take about 3 days to get to the moon and to go to our nearest star (besides the sun) it would probably be around 400 years
"no commercial space travel" uh, ever heard of ULA? Orbital ATK? SpaceX?
Of course, you still think they're fake.
Benjamin Casillas
I've herd of space x of course, the other 2 never herd of. But if you check space x has been absorbed into nasa. Nasa is their only customer. Like I said, no commercial space travel. Not even a ticket for a quick trip to experience weightlessness, and see stars, or see the curvature of the earth. Every countries space agency is the same. Its been 49 years since supposed moon landing. Face it, commercial space travel is never coming, because they are lying.
