Scalars and Vectors

[@akhan727]

I cannot stress enough how well you explained this. This video is refreshing!

[@xanderbotha5538]

This guy explains very well, even though you can't ask him. Helped me alot

[@ramkumar-mf6ct]

3-4 periods of lectures which lead me to this channel and after his videos I am back to school to teach my friends😎😎 Bozemann!!!!you are a boss man !!!

[@howdyslots]

I was having so much trouble with this... Not anymore! Thank you, Mr. Andersen!

[@ellmatic]

6:48 - I ask myself this question every day.

[@georgebotha6861]

^^ Truth ^^

[@mrwilkey]

So true

[@deborahsaunders3127]

You did a wonderful job with this video! It gave me great understanding of the difference between a Scalar and a Vector. I got almost all of the Scalers correct in the review. Thank you.

[@SirPhysics]

Love the demonstration and you explain the concept well. My only issue is that you use mass and weight interchangeably (force in grams) which can be confusing. Just call it a 10-newton (or even use pounds) weight from the beginning and it will be much clearer.

[@bakhadher2240]

you such a great teacher .thank you so mush . student from yemen

[@SoraHarukihartCookies]

Thanks for the vid! This helps for my report in Science. I really had a rough time studying and researching. Thanks again!

[@MS-tf5su]

Thankyou so muchhhh !!! I saw a lot of videos on youtube about Scalar and Vector quantities but couldn't completely understand.. Your video was the best :) I already subscribed to your channel.

[@Heavygatz]

You're a real genious!!! I'm amazed you almost know everything!!!

[@Spider2015]

what a way to study for finals. Thank You very much. God answered my prayers

[@stanlynathan8718]

This was great. Thanks for posting! 👨‍🏫

[@MilkLubb]

I just learned more information then I had at school today.

[@sylviamieze8768]

I now understand this, thanks 👍 for the help

[@oa793]

thank you so much really cleared things up, great teacher!

[@theindiana5114]

It is really good videos for understand scaler and vector.

[@celin3598]

awesome...i was struggling so much thank you!

[@BrowningMath]

Thank you, Paul!I will show it to my students tomorrow, We start vectors:-) I plan on starting with philosophical chair "Whether two people can pull out a puppy from the hole

[@adarshyadav253]

Nice demonstration

[@FahadAli-bp4zb]

Ur explanation is super great

[@sujithsubramanian748]

Good to get back to basics .. Thank You.. Was very helpful.

[@fazilat8648]

wow what a explanation it is very practical with understandable english thanks

[@AslamKhan-ul9no]

This helps to understands physics very well thanks

[@stephenmwaura6642]

Thank you so much for your help. I wish you are my physics teacher

Timmy Baek did u pass?

[@sweetyjasmine7410]

@Kim Quach poor

[@iSpeakUnknown]

This was helpful, thankyou! I finished my report, so thanks again! :D

[@prachetaghosh2308]

amazing videos..very good teacher

[@Milkylim1997]

i cannot understand what my teacher is teaching about at school but i can understand what you are saying about ^^ thanksssss a lot XD

[@ctoumi2]

very good example - 9/10

[@astropoptart04-56]

Anyone here from 2021 he taught me more than my actual teacher

[@harrymallory6566]

Great stuff. Explained quite well!

[@rubinsingh1851]

nice video man ... really helpful.

[@theelitebum5913]

9 years later and teachers are still assigning this video for students to watch 😅.

[@blackspotedcow]

Wow this is way better then what my teacher shows my class. Try learning this stuff/chemistry by a youtuber named crash course.

[@darryltaylor3803]

I sat in my introductory Chem/Phys class in college and asked my professor what difference did it make whether I identified something as either scalar or vector.....the light bulb finally turned on.

[@juliacullen1986]

This was so clear !!! Thanks for posting !

[@meetvetri]

Good one thanks for posting

[@pakistaniart4666]

Great teacher 👍

[@hueance]

great stuff enjoyed it thanks

[@henryegbe6496]

thanks a lot. really helpful

[@arham1079]

Good video. Really helped!

[@baldevrawat]

Thanks a lot... really helpful.

[@AnimeFreakPhill]

My Physics teacher told us to play Angry Birds Space when it came out.

[@kartarsingh9557]

Thanks very much

[@gurvinderkaur9686]

Your an Amasing teacher

[@Nathanacosta00]

Yeah when I do rope hammer curls (100lbs btw) it is significantly harder to bring my hands away from the center than it is to keep them together.

[@grantacox]

Great video. Clear, good examples. If you don't mind, I have a question about the technology you need to make videos like this. I have a Mac and a cheap webcam. What else would I need? (I'm also a physics teacher, just starting out on making videos for my class. So far, I've just used the webcam, index cards, and photo booth). Thanks for any help you can provide.

[@danieldelic9172]

good enough

[@THRILAH]

thanks this really helped me with my study keep up the good work =p

[@Gotchya97]

Watching this on summer break... Hahah. c:

[@kumarar745]

Very nice

[@fardeen_0047]

Hey viewers, Mr. Anderson circled pressure to say it is scalar but pressure is just a force/area and force is vector then, how pressure could be scalar?

[@waqasahmad2939]

Pro Gamer when we put a gas in the cylinder/container it exerts pressure(F/A) in all the direction across the walls of that cylinder/container thus the direction of quantities involved in pressure remain fixed pressure become scalar quantity.

[@MegaLock12345]

Shoutout from CVHS

[@marcelfoto1]

please do a video about blast waves

[@LeoKasper426]

I wish he was my teacher!!! He’s fun!

[@negroween]

Where have you been all my life?!?!?!

[@LRNFZX]

265K views at this writing and mass/weight (scalar/vector) are consistently confused in the video. Major problem. Mass is a scalar to be measured on a balance in metric units of kg or g. Weight is the vector to be measured on a scale in units of N. The only reason that stupid scale is labeled in g is because mass and weight are proportional since W = mg. This confusion of mass/weight will lead to problems with all of Newton's Laws of Motion and Gravity and Satellites and Energy - basically all of Mechanics. These will help with that distinction: Mass vs Weight, Balance vs Scale: kzbin.info/www/bejne/i2ndY4mtqad7iaM I Was Wrong - Mass vs Weight: kzbin.info/www/bejne/Z2Sqq56Lo7-cq7M

[@SamuraixJack]

Mr. Anderson. I'm currently brushing up on some mechanical engineering, even joined the club at my school. Is there any difference between drag and friction?

[@YuvrajSingh-io8gu]

***** thanks dude☺

[@mellowpipes7105]

thx man, really good

[@laibamalik5162]

useful information

[@DropMadBombs]

@makinmimis77 Mr Andersen knows a ton about everything, although as an old student of his I can tell you that he rocks the most at science :)

[@thomasanderson1416]

I got all of them except pressure, I guess it's 'complicated' because on the micro level it's definitely vector value.

[@Gogododo23]

Pls do more videos on physics

[@paritoshambani2573]

Thanks really helpfull

[@gianfranco5759]

Around 8:18 of the video he's talking about how both scales are supporting the kg weight at a angle both with 1kg of force. I thought kilograms were a unit of mass and we use newton's as a unit of force but after watching this it confuses me alot can someone please explain and clarify why this is.

[@argus1392]

+Batroc Y I think its because weight is also measured in kilogerams altough its just the force of gravity? Altough, i think there is a specific unit for it like a " force-kilogram" or something like that :P

[@DontMissVideos]

Thx for this! helped alot

[@hirukabadugama1221]

Sir,is area a vector?

[@DragonGooey]

Thank you for these videos!! I am not taking physics right now in high school, so this is great! lalala~~~!

[@TejSwaroop]

can someone please explain why is pressure a scalar. just like dimension analysis Pr = force / Area where pr is dependent on vector data type - force

[@sumsar01]

+Tej Swaroop Just a guess of the top of my head F=(-F)

[@TejSwaroop]

+sumsar01 in a system it might / might not cancel but that does not make a quantity scalar or vector

[@romandeprez]

+Tej Swaroop pressure is in all directions and not just one making it a scalar.

[@chandrasekhar-gk7jm]

Durgesh Karpe pressure is scalar because it is normal force per unit area where the normal force is component of resultant foce so it becomes scalar

[@Theycallmehoff]

Thanks!

[@APC9906]

thumbs up

[@karlvincecasitas3177]

thank you !

[@saraswatimandi6517]

what is magnitude

[@gulshinwari3420]

can some 1 plz tell me difference between magnitude and position...?

[@jackiecarl9609]

+Gul Shinwari Magnitude is how much of something there is, and position is where something is.

[@clancrybaby]

thanks man!

[@roshanelison6062]

thanks bro

[@supercard9418]

You're awesome

[@michaelunachi7413]

Nice video. Except that "saying 1000 gram weight" is not entirely correct in Physics. I wanted to show this to my students but i couldn't because i already taught them to express quantities in their correct units. Gram is the unit of mass, weight is measured in Newtons.

[@gloreyyachinaza3526]

Is weight a vector quantity?

[@allisonsheridan8101]

Gloreyya Chinaza yes.W=mg. And gravitational acceleration "g" has a direction which is downward.

[@gloreyyachinaza3526]

Amtul Shafi thank you

[@allisonsheridan8101]

U r welcome dear

[@Jennthepan]

i wish you were my science teacher.. ..

[@Jerry12132]

thanks dude :)

[@TejSwaroop]

Time in my opinion has direction and can be classified as vector , -10 secs ; 0 sec ("event") ; +10secs What do you say Internet ? :)

[@sumsar01]

+Tej Swaroop It is pretty much a one way train though. Some people theorize that anti-matter moves on the negative time scale though.

[@era2089]

negative here doesnt refer to direction time has no direction i cant go west in 7 minutes north😉😉

[@era2089]

Thank you :)

[@lakshmin8780]

good comedy at first and explain good

[@rickandelon9374]

I want all of you to know that //Vectors can be 0 and negative but Scalars can never be zero or negative!!!!

[@spankagev4582]

can you explain scalars can never be 0 ?

[@daniell707]

He realized just how danger 23 m/s would be when going around a curve and appropriately slowed to 23 miles per hour..

[@yahboip]

i need 2 know this in middle school.

[@manojkumarthumbalam6369]

pressure is a tensor

[@davethurlo]

Brenda, it's 9.8 m/s/s.

[@leonoramaya1157]

you kinda look like Matt Damon lol but thank you this lesson was helpful.

[@maximilianharvison9965]

i wanted to watch angry birds

[@piyushgarg1030]

Me too

[@JB-pj2lj]

Length and time are vectors my friend

[@chaoandy10]

1000 grams is not weight, it is mass. U got me confused
