12 - What are Vectors and Scalars?

In this lesson, you will about the difference between Vectors and Scalars and why these quantities are important in Physics, Math, and Engineering.

A Scalar is a quantity that has only magnitude. Examples are pressure, temperature, and time. A vector is a quantity that has both magnitude and a direction. Examples include velocity, force, and magnetic field.

We will use vector and scalar quantities extensively throughout this physics course and in engineering courses.

I'm 68 years old looking for material to help my grandchildren in their studies. I wish I had a teacher that could explain things as clearly as you do when I was at school back in the day. Thank you for taking the time to put these lessons together.

You explained the math and science topics in its clear and simplest way!!! Thank You!!!

[mrmcafeeboat]

Sir makes mathematics easier to understand very well I love it.

Sir,
I was recently trying to learn about vectors and scalars, I was not getting it properly because my teacher used to teach so fast, now I understood it correctly and now I get it, THANK YOU VERY MUCH
Thanking you,

i just started watching your lesson. I am really enjoying it

Thanks Mr. Jason, you have been blessed with that quality of understanding of what students could feel before a new subject, a rare gift indeed. Please accept my wishes of happiness and fulfillment in this 2023 New Year ! ✋ Keep goin' ! ❤

Thank you so much for this channel, I watch many of your videos and they helped explain things in great amount they’re not just cut and dry but have meaning !!

I have a question. You explained in this video that quantities that have magnitude and direction are called vectors, whereas quantities that only have magnitude are called scalars. But what about quantities that only have direction, like the degrees of a circle? If you travel in a 45° angle from your starting point, that is a direction, but it doesn't tell you how far you travelled. Is there a special term for those? Or are they just called "directions"?

[JBond-zfdj]

Once again...thank you!! You explain things / break them down so nicely.

I like how he's like "you've probably takin basic chemistry or physics" and there's just me I haven't takin any I only have taken a little bit of biology 😕. Ps but I understand most of it and thank you for your great teaching I can't wait to blow my teachers socks off with how smart I am lol.

Wow! His pattern of teaching makes learning easy.

Thank you sir

Jason thank you for these youtube videos!

[davidogbija]

Good learning sir, you are a great teacher indeed.

[pantydropperr]

Hé teaches better than 90% teachers in school

[UmarKhan-jdl]

Sir, if we use an arrow below the letter then would it be a right vector quantity? Plz reply me ❤

[skillybiskuit]

We are so amazingly lucky to have free access to such a vast amount of education.

[olaleyeboluwatife]

Thanks for dedicating your time . You teach so well, keep up the good work sir as GOD blesses you

[johnholme]

This is quality teaching! Thanks for the info!
