First, i wanna thank you so much. I live in Turkey and my English is not that good but even with that, i can UNDERSTAND what is your explaining. I search the same video in Turkish language and i found LOTS OF videos about it in my main language. But these videos have 5 minutes long. If you are not genius or something you can't fully understand a topic like that in five minutes. That's how it should be to teach something to someone. Again, thank you so much.
I have been studying calculus as a hobby for a few months now and I knew that velocity was a vector quantity which means magnitude a number and vector a direction but did not understand It because I didn’t understand direction but when he talks about direction of a rocket taking off at a specific angle theta light bulb went on. So to know the direction of a curve at any moment, we know the velocity at any moment. This instantaneous velocity is determined by the slope of the tangent line he we get by taking the derivative of the curve function.
I’m a little sad I’m 54 and just now absorbed the fundamentals of scalars and vectors, after years of (struggling with) math, calculus and physics classes. I remember having troubles with my intuitive understanding of vectors as a kid, and it really hampered my understanding of what I was doing in subsequent courses, and all it took was a 1-d demonstration on a simple number line to reinforce the concept. My life would have been much different with Jason’s teaching methods, and I had some pretty decent teachers.
You got it! It seems weird at first, but actually makes sense. Velocity is a measure over the whole trip from start to end including direction so if you start and end in the same place, then from a total trip point of view you’ve done nothing and that’s why the average velocity is zero.
Nice one again, Jason! Just a wee remark, that maybe it more people start pronouncing Uranus as greeks meant, then there will be less confusion and bad jokes ;) (ua-cam.com/video/idjPlOb-ANo/v-deo.html)
There is plasma, dust, molecules and atoms, and gas in space, with temperature being a measurement of the motion of those particles. You’re correct in thinking there would be no temperature in a perfect vacuum, but there is no perfect vacuum, even in interstellar space. Edit - oh crap, sorry, you knew this - I didn’t notice your smiley when I started thinking out loud. 😮
I would like to be able to run 5 meters per second! That's almost 3 full leg movements per second...that's fast! Cheetah can run 70 MPH but only for a short distance. A bear is what will fool you...they look fat and slow but they can run up to around 30 MPH and can climb trees!
Jason, you're a true professional for being able to keep a straight face while tongue-in-cheeking Uranus' vibes.
Well done! :) haha
Lol thanks much!
The best of the best! This teacher's teaching skills are millions and millions dollar worth!
Thank you!
Yes!!
Every remarkable video, every single days!!! Thanks a hexillion for sharing your knowledge with us!
So nice of you!
Best explanation for speed and velocity .I bow my head for your crystal clear teachings
I absolutely love this. My fav youtube channel by far.
Wow, thank you!
Thanks!
Welcome!
Could literally be the best teacher on earth. Thanks for making this publicly available.
best science teacher I have ever had.Bless you

Thank you very much and by your comment your English seems wonderful to me.
💜❤
Very interesting, love it. After completing my masters in 2012, I still want to recap lessons. Thank you so much

Great explanation velocity should be explained like this in calculus
You got it!
Thank you!
No way boring lesson. Thank You Doctor. I’m waiting for the conclusion .
Your presentation is great. Thank you sir --- from India.
I can’t believe I actually watched the whole video, you make it much more interesting then I originally thought it would be👍
Awesome!
God sent tutor. the best
Many thanks Sir Jason

BEST SOURCE OF INFORMATION EVER GIVEN
Born to be a educator.
Awww thank you.
Thank you Jason 🎉
Thanks 🙏👍 dear teacher 😊 the best explanation lesson
Thank you! 😃
Hhh muqidisho maa joogtaa mise 😂

Thanks you so much incredible for your support!!!
Thank you too!
What’s strange is gravity is more and less at different places. Not by much but something to think about.
why i havent see you in past i could be another level
You are a modern day Mr. Wizard (Don Herbert).
This is the absolute best compliment I’ve ever received. He’s one of my idols, and I used to watch him as a kid :-)
@@MathAndScience me too ...... should have posted 'You are a modern day Mr. Wizard (Don Herbert) FOR ADULTS'
any recomendation
Thanks a lot, Sir
Thank you sir
Hold on a sec, let me write that down...."Uranus is very very large"! OK got it 😆 🤣 😂 😹
THANK YOU... SIR...!!!
Most welcome!
Carefulness suggests time is not feed to become stronger.
Is it?
4:19 I think you scientists use Uranus as an inside joke :)
Remember, Uranus is big!
When you ask the diameter of Uranus I thought you were setting me up for a joke
Im glad someone said this
“It means that Uranus is really really big” how on earth do you say that with a straight face with all that build up!!
Interesting may I get ur contact
3:50 & 11:35
Wow!!!!! It’s been proven that Uranus is huge!!!!!!! 😂😂😂😂😂😂😂😂 Math is finally being used for seeking the truth!!!! Good on you math!!!!!!
If I understood well , an object goes to the moon n comes back to the same point on earth. The velocity is zero .
Thanks for the video.
You got it! It seems weird at first, but actually makes sense. Velocity is a measure over the whole trip from start to end including direction so if you start and end in the same place, then from a total trip point of view you’ve done nothing and that’s why the average velocity is zero.
@@MathAndScience thanks !!! 😊😊😊
why you are giving figures in km and not miles?
Nice 👍
Thank you! Cheers!
Its funny how some of your most recent videos could be used in warfare.
thank god you use metric system
Ah, I see now how a 47min video can be considered to be a 10minute video. Its all relative.
Laf, no - it’s a 47min average time vs a 10min time displacement. :)
Now, I understood why the vehicles have only speedometers. How much time it takes for the light to reach the earth from the moon.
Just a few seconds light time from moon to earth.
It means that Uranus is really really big 🧐
Nice one again, Jason!
Just a wee remark, that maybe it more people start pronouncing Uranus as greeks meant, then there will be less confusion and bad jokes ;)
(ua-cam.com/video/idjPlOb-ANo/v-deo.html)
But it’s more fun this way :). Thanks very much! I appreciate it.
@@MathAndScience Sorry, one more suggestion. Perhaps, you should've included an example of Average Velocity = 0 when Average Speed > 0
Why is there a temperature in space if there is no air there then? :)
There is plasma, dust, molecules and atoms, and gas in space, with temperature being a measurement of the motion of those particles. You’re correct in thinking there would be no temperature in a perfect vacuum, but there is no perfect vacuum, even in interstellar space.

Chuckle, just be sure to run WITH someone slower when trying to out-vector Smokey.
👍🌷👍❤
4:08 really?😂
i know you like physics sir
U remind me of don herbert
Yes! Love this!
