This guy deserves more views. I've gone back to University after teaching ESOL overseas for 10 years, and COMPLETELY lost in physics coz they teach like we remember all the basics out of highschool. This is so simple and easy to understand, and thorough (for such a basic overview style). Cheers mate, I'll turn my addblock off on your vids.
Thank you for these videos! I've been having so much trouble in my 200 level Physics class, it's been driving me INSANE! These are a great overview of key topics!
I'm a college freshman student and I'm about to take the very first physics course in my life. I never took physics in high school and I dropped math eventually. I was thankfully able to understand the differences between vectors and scalars from this video, as well as trigonometry. Calculating vector components sounds a bit complicated to me though. I still have an interest in astronomy and physics, and this channel is helping me understand the main concepts of my classical physics class. Just currently praying that this class won't end up in disaster for me. Thanks Dave.
@@Silent_Quasar Oh yeah I remember this comment. I ended up completing Physics 1 & 2 and this course helped a ton. It was super hard but I got by with a B. Now I'm a senior engineering student!
@@Silent_Quasar Im happy to hear that! My astro/physics interest is more of a hobby for me nowadays. But the way I got through physics and math was just by passing. Now I'm in electives that I thoroughly enjoy with work I don't stress over. It's a lot of fun, I don't regret it.
as a high school student teaching myself physics over the summer, I wanted thank you for everything you offer on your channel! this is far better than khan academy for my style of learning. My goal in life is to never stop learning, and you have made that goal far easier to obtain! thank you Professor Dave!
Hello! English isn't my native language, but i want to study abroad, so i should learn subjects in English, and here you channel really helps! Thaaank you so much!!!!
Do you teach in a university. I mean what do you do apart from these extremely great video lectures ? By the way, your lectures are extremely great and I can confidently tell that you are one of the greatest teachers in the world.
thanks kindly! i used to teach organic chemistry at a little trade university but now that the channel is picking up steam i just do science communication and freelance curriculum development. it's a lot of fun and i look forward to building the channel as much as possible! please spread the word!

Thank you again for explaining the math side in such a pure simple way for us newbies to physics in a long time. The simple click that vectors are in relation to the Pythagoras equation. Thanks :D
Nice!! Thanks man! Professor Dave rocks! I am a software engineer... and sadly, 5 minutes ago I didn't know what a vector was or a scalar lol. Now I know how to find sin, cos, tan. 5 minutes ago I didn't know what those terms even meant. ... of course I knew at one point but long forgot
christ I never understood algebra and using cos/sin was a mystery to me as a kid but just putting it down like this visually instantly makes it make sense, thanks
You are the best really Now I understand anything, but at school I can't So thank you for your lessons and efforts. This video was really interesting and helpful for me I wish you all the best in your life 🤗🤗🤗🤗
Thank you for explaining things in a way so that someone like me might understand. I like to learn, but sometimes I need a lot of dumbing down. Thank you!!
In the boat example, it depends whether you want to cross as fast as possible or to take the shortest path from bank to bank. If the latter, then you should point the boat upstream and the result would be sqrt(15) m/s and zero degrees.
I've been adjacent to your videos, and have watched some to better understand some topics in calculus and chemistry, as well as your videos involving the flat earth community and arguments with that one "apologist" (i forget his name), but i didn't know you made more comprehensive series for large topics, thanks!
Thank you Mr. Dave. I always wish i had a dry erase board when I talk to people. I will refer them to you. ( I teach music, but harmonic sequences....DOH!)
Found you from your Globe Busters smackdown. Making my way thru your tutorials cause you teach so well. But damn the difference in your hairstyle threw me 🤣 not bashing it, just surprised me lol
Thank you so much! Your explanation is amazing ! But i didn't get how to calculate the inverse of sin, cos and tan, yet. I'm going to search a bit more. Am from Brazil👏
I have listened to 100s of videos on physics. Big fallutin ivy leaguers. You beat them hands down, period. Plus you are physics math and chemistry rolled in one. My retirement plan is set.
I don't know why some people dislike your video, don't subscribe to your channel, don't watch your videos. Do you have any solid answer of that WHY? Because I don't know.....
At 8:00 Prof Dave made a mistake. According to how the question was asked, if the boat is travelling upstream at 4 m/s and there is a current of 1m/s downstream then his resultant velocity would be 3 m/s upstream. The question said nothing about the boat travelling perpendicular to the current. I realise that travelling across the river might imply from bank to bank but this would be an assumption.
Why is the current point downwards? I would expect it to be just interpreted as -1 so the netto speed would be 4-1=3 m/s. Could somebody explain to me what I am doing wrong here.
Yea I got confused too, but eventually realized he meant crossing the river and not traveling along with the river. Crossing from one side to the other, hence pushing the boat to the side and not backwards. Looks like in physics you *really* need to be on point taking things into account

If I had math and physics teachers like you in high school, I might not have majored in literature.

funny but I relate
your teachers like mine, were not that good.
Relatable. Because I'm also looking forward to major in literature.

Professor Dave is my new physics professor! Thank you for your videos, they have helped tremendously!
Thank you Professor Dave !!! It helped me alot !! Plz make a video on cross product and dot product of two vectors !! It would be a great help !!
that's coming soon!
Professor Dave Explains thank you sir
Thank you for these kind of videos your lecture help me to understand physics and now i find physics more interesting 💜
love your intro music, never change it EVER!!!

Since I don't have any idea about vectors, watching this helps me a lot❤ thank you Prof. Dave
Gonna binge this series (and as many others as I can) all the way through this holiday!
If anyone cannot follow the SOCAHTOA mnemonics device, it might be better to memorise this mnemonic device:
*S*ome *P*eople *H*ave
*C*urly *B*rown *H*air

This denotes:
Sin θ = Perpendicular/Hypotenuse
Cos θ = Base/Hypotenuse
Tan θ = Perpendicular/Base = sin θ / cos θ
U are one of the best (if not the best) teacher I've ever had
If u can’t donate him money pls do watch full ads.....so that he could get some money..🤗 I watch full ads ...As he os a grt teacher
yes please! and even click on the ad if you're feeling generous! that's how i get paid :)
Will do!!
Me too. Since I can't donate.
But I'm very grateful for his videos
dont tell me what to do

... of course I knew at one point but long forgot
I'm watching your videos from India. I feel blessed that I am learning from you. Thank you very much sir 💓💓❤❤💓❤💓❤
its 2022, and this man still saving lives. Time to binge all the vids
Basic concept explained in simplistic words... it helps in laying strong fundamentals of discussing subject. Thx prof. dave..
christ I never understood algebra and using cos/sin was a mystery to me as a kid but just putting it down like this visually instantly makes it make sense, thanks
I understand almost everything,
When professor dave explains
Professor Dave I owe you my life
Thank you so much! I hope to watch more videos from you. You enlighten me. God bless, SIR! You deserve a BIG THUMBS UP!
This video made things so much simpler than in my physics class
ua-cam.com/video/wjcOW6hmjfY/v-deo.html
A whole a lot easier lol
long live professor Dave !!
Finally a great explanation! Even you explain the reason behind all the formula!
Honestly you made this super easy
I love your teaching style
Thanks
Your lectures are truly amazing. Love your work, please do not stop. ❤
its 2019 and i am watching this dude i am lost in ig physics you really help man
Omg 2019?! Back where everything in the world used to be good... Atleast for me it did...
@@TouhidLota lol 2019 was kinda not good for me. good for everyone who had good old days tho
This is awesome, thank you Professor Dave!
Its 2021 and your vids are still helping us! Thank you!
Thank you sooooo much u just summed up 3 whole lessons in a 10 minute video that was sooo helpful thank u again!!
So far physics makes sense.
all the contents were very clear to me. It was so easy to understand.
You are the best really
Now I understand anything, but at school I can't
So thank you for your lessons and efforts.
This video was really interesting and helpful for me
I wish you all the best in your life 🤗🤗🤗🤗
You are a totally renaissance type of person! Amazing.
Helped me with math tysm
will you be going through history of how these methods were discovered? (ie Galileo's ramp experiment that discovered the independent x and y Forces)
ooh good idea! maybe i'll add it to the list.
glad i could help :)
the intro always makes me feel alive and ready to learn lol
Thanks so much for this! Really easy to follow and very understandable! My deep appreciation!
2:01 did i just hear?
"you Do nOTE" HAHAHA
Nice! Really useful - good enough for a 10 year old!
my ten year old son really liked it
It was SOOO clear.

You are doing a very good thing by explaining these things for free.
In the boat example, it depends whether you want to cross as fast as possible or to take the shortest path from bank to bank. If the latter, then you should point the boat upstream and the result would be sqrt(15) m/s and zero degrees.
I've watched this video about 4 times. I think I'm ready for the next lesson.
You are making me remember stuff which is making me miss school Sohcahtoa OMG!!! how could I forget that?
I was watching this video at 1.25x speed and it took me pretty much exactly 7.4 minutes to finish by the end. Are you a wizard, Mr. Dave? 1:14
Excellent explanation.
His videos are short but informative! Thanks!
professor Dave ROCKS!!!
@75, I needed a review of Newtonian physics. This looks good.
This guys the reason im gonna get into physics
I've been adjacent to your videos, and have watched some to better understand some topics in calculus and chemistry, as well as your videos involving the flat earth community and arguments with that one "apologist" (i forget his name), but i didn't know you made more comprehensive series for large topics, thanks!
Awesome and helpful videos... Ur videos have always helped
Thank you for this great video
my science teachers loves this guy for some reason
because i'm the shiznittle bam shiznat
@@ProfessorDaveExplains i thought u were professor dave
@@asmallmistake that's me, bud.
Sin, Cos, Tan can be also remembered as ' OLD HARDY AND HIS OLD AUNT ' that is Sin= O/H , Cos= A/H, Tan= O/A
Thank you professor to make it easy to understand ..now I will correctly learn
Thank you prof. Dave
Who in the seven seas has been disliking these purely scientific videos
the jingle sounds especially good in this video for some reason
thanx this is very helpful for my studies
Physics too ❤
such an inspirational video 10/10
love it your video sir...really gret sir
this is an incredibly informative video,

the quadratic formulas aint woking for me...i mean i worked it out and the answer aint the same with yours and believe me i tried lots of times.
