How Does Speed & Velocity Work? What is a Vector?

Here we discuss the essential concepts of distance, displacement, speed, and velocity. Distance is the total meters as an object move. Displacement only takes into account the starting and ending point of the motion, and is a vector quantity. A vector has magnitude and direction, while a scalar only contains magnitude information. Speed is is a vector, while velocity is a vector and contains speed information along with the direction of travel.

Every remarkable video, every single days!!! Thanks a hexillion for sharing your knowledge with us!

[@MathAndScience]

So nice of you!

[@AirwavesEnglish]

Jason, you're a true professional for being able to keep a straight face while tongue-in-cheeking Uranus' vibes. Well done! :) haha

[@MathAndScience]

Lol thanks much!

[@ottofrank3445]

The best of the best! This teacher's teaching skills are millions and millions dollar worth!

Thank you!

Yes!!

I absolutely love this. My fav youtube channel by far.

Wow, thank you!

4:19 I think you scientists use Uranus as an inside joke :)

[@MathAndScience]

Remember, Uranus is big!

[@83jbbentley]

What’s strange is gravity is more and less at different places. Not by much but something to think about.

[@GeorgiHadzhigeorgiev]

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 ;) (kzbin.info/www/bejne/n5XNgZ-Fl5J0hNE)

[@MathAndScience]

But it’s more fun this way :). Thanks very much! I appreciate it.

[@GeorgiHadzhigeorgiev]

​@@MathAndScience Sorry, one more suggestion. Perhaps, you should've included an example of Average Velocity = 0 when Average Speed > 0

[@xaimeglez74]

Wow!!!!! It’s been proven that Uranus is huge!!!!!!! 😂😂😂😂😂😂😂😂 Math is finally being used for seeking the truth!!!! Good on you math!!!!!!

Awww thank you.

[@davidvolland7250]

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.

[@davidvolland7250]

Great explanation velocity should be explained like this in calculus

[@MathAndScience]

You got it!

[@MathAndScience]

Thank you!

[@vsdsas]

why i havent see you in past i could be another level

[@joedasilva134]

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.

[@MathAndScience]

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.

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!

[@ronjon7942]

Chuckle, just be sure to run WITH someone slower when trying to out-vector Smokey.

why you are giving figures in km and not miles?

Welcome!

[@ronjon7942]

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.

Carefulness suggests time is not feed to become stronger.

Is it?

[@jaanix_2293]

Why is there a temperature in space if there is no air there then? :)

[@ronjon7942]

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. 😮

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.

[@MathAndScience]

Just a few seconds light time from moon to earth.
