What is a Vector in Physics, Math & Engineering?

[@myda2856]

Just what I needed. All the work you do to help people is absolutely unreal. I decided to go back to school for Electrical Engineering, and was horribly anxious about the math involved. Your website helped me realize I love math, I just never had the right teacher!

[@JulietNovember9]

Same here! Change of careers to EE. First day of class is next month and this channel has been amazing for my math review. Good luck to you!

[@Spencer_Bikes]

Same here! Just finished up my Freshman year. Best of luck to you!

[@surajshukla6813]

I learned so much from this lesson. Really loved the way you make it so easy to understand. Thank you sir 🙏

[@nathanjohnnie6768]

Excellent refresher for vectors. Thank you!

[@ironBird83]

my like for this video is for the four time he emphasised on the important stuff....every teacher must do this in class.

[@HomeByTheSeas]

Repetition is key to memorization!

[@DoLtYsh]

You’ve helped me so much to understand the Quantum Gravity Field n now I’m a astrophysicist in reality n I can explain to folks. I love your way of explaining

[@yogibruh9556]

Is this real?

[@DoLtYsh]

@ if you ask the right question on the first place and try to get to the answer; answer is hidden in different variables n you slowly start to peel it layer by layer like an onion.

[@KouroshBozog]

A very useful video for me, thanks

[@0_0merry]

I needed exactly this. The basic meat and potatoes explanation of what a vector is, thank you!

[@andrewliberman7694]

Thanks!

[@MathAndScience]

Wow thanks much!!

[@dadadavid1409]

It's amazing how you explain this concept. I hope you make a video on vectors in Maths. Thanks!

[@JohnBond-m4t]

I knew what a vector was, but you have an interesting angle on the subject .

[@Mash88-c7k]

Can't wait for the video to add vectors 🎉🎉

[@djc736120]

Hello professor. I understand the concept of a velocity vector representing the velocity at the point. Thank you for making that clear. But, what about velocity vectors drawn on a motion diagram ? I was taught that velocity vectors drawn on a motion diagram represent average velocity over the length of the vector. Can you explain this better? This confuses me a little bit. Thank you sir. You are very good at explaining things.

I dont know if you reply here, but i have a question at 20:12 you said it doesnt matter the middle part of the displacement, it only matters the starting and ending point, but if we move here and there and then finally reach at destination, dont we call it distance instead of displacement? we have studied in our books that if we move from point A to B in specific direction than we call it displacement, and if we move here and there and then reach point B than we call it distance, kindly clear that. Thanks

[@MathAndScience]

If you travel from point A to point B and have a bunch of different stops back-and-forth and back-and-forth along the path then if you add up the total distance you traveled from A to B including the zigzag that’s called the distance. It’s not a vector. It’s just how far you went, including all the back-and-forth. The displacement from A to B would be ignoring all of the intermediate stops and just looking at the starting point and the ending point and how far you traveled in a straight line from A to B and also what direction you traveled from A to B ignoring everything in the middle - that is the displacement.

Nice 👍

Thank you so much, sir Jason.

[@CertifiedSkank]

Maybe if I watch enough stuff like this I’ll know math.

[@dadsonworldwide3238]

Really great details that aren't understood. Even in general conversations with loose reference order of magnitude vectors and scaler terminology throws people for a loop and they're guilty of blaming me for being to phylosphical about things lol This seems to be more of a recent issue as opposed to talking with those who grew up being taught more about dialectical vision minds eye positioning. Or machinest & tool and die all pick it up. .someone who really understands galleos ship & history of discovery & language gets it all.

[@alexprokhorov407]

Time is not a one line movement, time greatly depends on curvature of space, especially when, and they often do, massive objects are present. You take time as a fourth dimension, but it can change with the other three as time depends on the volume and actual shape of the volume.

[@robinrothe9369]

In simple terms - time is affected by gravity. Since the universe is expanding, c is not constant. Think about that for a time. If what I have said is true, then all of the atomic constants are not constant. So does that mean we are living in a virtual reality?

[@anonymousnoname3022]

Whats your vector victor?

[@frankroper3274]

In air conditioning we are taught the concept that heat moves to cold. Heat energy always flows from a warmer to a cooler object. Would that not be a direction from warmer to cooler?

[@muhammadhussainsarhandi9928]

That's right, but a vector is defined as any physical quantitiy that has magnitude, proper unit and spacial/spatial direction. "Spacial" word is derived from "Space". And by space, they mean x-axis, y-axis and z-axis. Warmer and colder are not spacial directions, which means you can not locate warmer or colder along x, y or z-axis. That's why heat does not belong to verctor family as it does not satisfy spacial direction.

[@frankroper3274]

@@muhammadhussainsarhandi9928 So would light not be included with temperature since it expands in all directions? There is a degree of light in the atmosphere the same as temperature.

[@hemrajue3434]

Time is no doubt a scalar quantity but not a physical one.

[@toolman550]

A good lecture but rather basic in Electronics we use vectors all the time in an series RC circuit the vector of 45° is called a half PowerPoint it means that the output is -3db down and is the knee where the circuit will drop off a -20db per decade for a single pole filter

[@alexprokhorov407]

I disagree on all points. Time iis relative. Mass has certain amount of atoms in moles but there's great uncertainty even with best instruments at this day. And pressure, well, it greatly depends where you measure it from. All of those are NOT scalar figurei. Even the speed of light is not scalar, although it's maximum speed in vacuum is established, there were speed of light in liquid helium that were below 20 meters a second
