I cannot stress enough how well you explained this. This video is refreshing!
6:48 - I ask myself this question every day.
^^ Truth ^^
This guy explains very well, even though you can't ask him. Helped me alot
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 !!!
I was having so much trouble with this... Not anymore! Thank you, Mr. Andersen!
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.
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.
you such a great teacher .thank you so mush . student from yemen
You're a real genious!!! I'm amazed you almost know everything!!!
mr.mr. ANDERSON man u rsimply awesome.
thk u a lot.pls pls continue ur contribution.
What?
Thanks for the vid! This helps for my report in Science. I really had a rough time studying and researching. Thanks again!
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.
what a way to study for finals. Thank You very much. God answered my prayers
My Physics teacher told us to play Angry Birds Space when it came out.
9 years later and teachers are still assigning this video for students to watch 😅.
Nice class be active and smile when you explain
It is really good videos for understand scaler and vector.
I just learned more information then I had at school today.
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.
very cool, like the example made it crystal clear
This was very helpful. Many thanks!
thanks for your wonderful demostration
Thanks for the help :) studying for exam tomorrowww T_T hahaha
Timmy Baek did u pass?
@Kim Quach poor
Nice demonstration
This was helpful, thankyou! I finished my report, so thanks again! :D
I now understand this, thanks 👍 for the help
This was great. Thanks for posting! 👨🏫
thank you so much really cleared things up, great teacher!
Good and attractive introduction.. ! Well done....!
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
i cannot understand what my teacher is teaching about at school but i can understand what you are saying about ^^ thanksssss a lot XD
Wow this is way better then what my teacher shows my class. Try learning this stuff/chemistry by a youtuber named crash course.
very good example - 9/10
Good to get back to basics .. Thank You.. Was very helpful.
This helps to understands physics very well thanks
Thank you so much for your help. I wish you are my physics teacher
awesome...i was struggling so much thank you!
wow what a explanation it is very practical with understandable english
thanks
Anyone here from 2021 he taught me more than my actual teacher
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?
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.
Ur explanation is super great
I got all of them except pressure, I guess it's 'complicated' because on the micro level it's definitely vector value.
Where have you been all my life?!?!?!
Great stuff. Explained quite well!
This was so clear !!! Thanks for posting !
amazing videos..very good teacher
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:

Watching this on summer break... Hahah. c:
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.
good enough
nice video man ... really helpful.
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.
thank you!
Shoutout from CVHS
Good one thanks for posting
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?
***** thanks dude☺
Thanks very much
Thanks a lot... really helpful.
great stuff enjoyed it thanks
Good video. Really helped!
Great teacher 👍
I wish he was my teacher!!! He’s fun!
I want all of you to know that //Vectors can be 0 and negative but Scalars can never be zero or negative!!!!
can you explain scalars can never be 0 ?
Very nice
thanks this really helped me with my study keep up the good work =p
Your an Amasing teacher
Sir,is area a vector?
thx man, really good
please do a video about blast waves
what is magnitude
@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 :)
Thx for this! helped alot
useful information
You're awesome
Time in my opinion has direction and can be classified as vector ,
-10 secs ; 0 sec ("event") ; +10secs
What do you say Internet ? :)
+Tej Swaroop It is pretty much a one way train though. Some people theorize that anti-matter moves on the negative time scale though.
negative here doesnt refer to direction
time has no direction
i cant go west in 7 minutes north😉😉
negative here doesnt refer to direction
time has no direction
i cant go west in 7 minutes north😉😉
negative here doesnt refer to direction
time has no direction
i cant go west in 7 minutes north
negative here doesnt refer to direction
time has no direction

Length and time are vectors my friend
i wish you were my science teacher.. ..
He realized just how danger 23 m/s would be when going around a curve and appropriately slowed to 23 miles per hour..
Pls do more videos on physics
thumbs up
can some 1 plz tell me difference between magnitude and position...?
+Gul Shinwari Magnitude is how much of something there is, and position is where something is.
Thank you for these videos!! I am not taking physics right now in high school, so this is great! lalala~~~!
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
+Tej Swaroop Just a guess of the top of my head F=(-F)
+sumsar01 in a system it might / might not cancel but that does not make a quantity scalar or vector
+Tej Swaroop pressure is in all directions and not just one making it a scalar.
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
Thanks!
Brenda, it's 9.8 m/s/s.
Thanks really helpfull
thanks man!
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.
+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
thanks dude :)
Is weight a vector quantity?
Gloreyya Chinaza yes.W=mg. And gravitational acceleration "g" has a direction which is downward.
Amtul Shafi thank you
U r welcome dear
good comedy at first and explain good
Is it ok to ilustrate grams as a vector? isnt it going to confuse people?
pressure is a tensor
Thank you :)
i need 2 know this in middle school.
thanks bro
Thanks! :)
1000 grams is not weight, it is mass. U got me confused
i wanted to watch angry birds
Me too
the question is though......how do we do math? scientists one unsolved question
Angry birds made this interesting to me.
