Every Tuesday I have a 2 hour long lecture on physics, after the class I come to your guidance and I learn so much about the same topic but in less than 5 minutes! Thank you so much Professor.
for coming to Italy, i learned Italian from you, now i am studying at university .. i am still learning everything from you.. i hope the best for you always and everywhere .. i really dont know how to thank you ...
my teachers act like as soon as they explain something you should know everything about it but when I watch your videos, I do know everything about it.
Sweet this makes it waaaaay easier to understand IR spectroscopy ....I swear, IR is just about the most difficult thing I have encountered that I have to go back constantly over every time I have to use it....I'm getting there, but it's annoying. Only 1-H and 13-C NMR is worse. Thanks Dave, you the MAN! (..^.^..)
Dear professor thank you so much for ur videos l understood their entire Mechanics from kinematics to dynamics within a night ,thank you so much hope God bless's u and ur good work ,u really work wonders thank you❤
hey thanks for making these videos! I am taking 2 physics courses over the summer so I will definitely be watching all of these (and liking and sharing links too lol)
Explain relationship between newton's third law of motion and reflection of light. Or Differentiate , in your next coming video Plz plz plz plz I hope you are honest professor .
All jokes aside Dave. I was a inspector for a railroad and there is something called a harmonic unbalance it say. The difference between cross level between rails in 7 consecutive joints can not exceed . If I remember correctly it is 1 and 5/8 of a inch and if it does the track must be slowed to 10 mph. . Rail length are about 32 feet so a joint are staggered every 16 feet . If not a train car will rock off a track. I assume it is similar to a tsunami in the ocean.. why would that cause a harmonic unbalance.?
At 2:22 you said that force exerted by the spring is always opposite the motion But while coming towards centre, force and motion are in same direction. Shouldn't it be like ' force is opposite to the direction in which spring is streched or compressed' ??
I'm sure that's ultimately what he meant. The spring force is a restoring force, which is proportional to and opposite the deformation from its neutral unstressed position. The spring force doesn't "know" what the velocity or acceleration is of the mass. Viscous drag would be proportional and opposite the velocity, while the apparent "inertial force" (D'Alembert Force) of the mass is proportional to and opposite the acceleration.
It's acting opposite to the direction of the force we apply, suppose a mass is connected to a spring. We apply the force on the right side, the spring tries to pull us backwards to get back to its natural length. That is, to restore equilibrium. So the force is negitive.

He knows a lot about the science stuff, professor dave explains! This intro song is stuck into my head, help.
i read this while the intro was playing
i remember that episode of the regular show
ME TOO HAHAHA
@@kevc6666 bruh
After reading your comment it’s now stuck in my head 😂

Yesterday my sir explained about this but I didn't understand ,but now I clearly understood about this ,thank you so much professor 🙏
this was 3yrs ago, thankfully i saw it here i really need it. my teachers lecture was not enough
This man looks like a walmart version of jesus, I love it
😂😂😂
hahaahahahhahaha
haha
Walmart version of an Afghanistan?
🤣🤣🤣🤣🤣
Thanks!

THANK YOU SOOOOOOOOOOOOO MUCH THIS SAVED ME RIGHT BEFORE MY EXAM!!!
This is just the perfect way to learn physics , love it
This dudes intro is honestly mush better then half of the intros out there not gonna lie🤩
Neatly explained, Mr. Dave
thank you for this video just learned that the force is always negative because its acting in the opposite direction
Dear professor thank you so much for ur videos l understood their entire Mechanics from kinematics to dynamics within a night ,thank you so much hope God bless's u and ur good work ,u really work wonders thank you❤
you are saving my life!!!!
Thank u we are following from Rwanda🇷🇼
This video reminds me of my late friend Elliot 😢, the action of the spring reminds me how he used to caress my skin back and forward 🫶🤞
Thank you very much man I was having so much trouble
Thank you so so so so much you're a life saver I can't thank you enough! I wouldn't be able to get through IB physics without you :)
How is your exam now?
I can't thank you enough,sir
sir,I live in bangladesh.your lecture is very nice!!!
this channel has made watching linus tech tips ten times easier
hey thanks for making these videos! I am taking 2 physics courses over the summer so I will definitely be watching all of these (and liking and sharing links too lol)
Fvg
How aren't you famous yet
4:11 why we put (-)for (f)
negative sign indicates force is in opposite direction
The negative sign in the equation is simply indicating that the force is opposite of the direction of the spring displacement.
From india here...you explanation is absolutely awesome. I understand everything here thanks a lot professor Dave
Thank 's it teaches
I am a Earl of March gr 12 students and thanks for helping us get through Mr. Inman!!! :)
I really really love your discussion.
Explain relationship between newton's third law of motion and reflection of light.
Or
Differentiate , in your next coming video
Plz plz plz plz
I hope you are honest professor .
Thanks for such a helpful video
I have cleared my all concepts
Excellent, thanks very much from Colombia.
My teacher can't explain these things as easily so this helps a lot
Thank you for your content! This is soo helpful
Thank you. Your are a genius.
i love your content, it is easy to understand. thank you😁
I love yr opening... sould make a 10hour version
Very nice thank you sir
That intro song is living in my head rent free💔😂😂.....way stuck than the school stuff
Thanks for the explanation Sir ❤️ From Sri Lanka🇱🇰
thank you so much!!!! your videos help me a lot professor.
buti ka pa naintindihan ko modules hinde salamat po sir dave💚😔
thank you Professor Dave❤
thank you sir
Thank you teacher i always watch your videos 😊😊😊
On seeing the process of teaching so great!!! why so less subscribers?
Saviour of my studies
I thank you professor for changing me you are really Intelligent
I am a designer but I should learn more about science so you earned my sub.
You are the best professor!!!!!
Thanks professor
You teach very well sir! Got it 💓
Thanks Dave. Your video reminds me of Baywatch. There is a lot of harmonic motion seen when people run on the beach.
All jokes aside Dave. I was a inspector for a railroad and there is something called a harmonic unbalance it say. The difference between cross level between rails in 7 consecutive joints can not exceed . If I remember correctly it is 1 and 5/8 of a inch and if it does the track must be slowed to 10 mph. .

Very well explained! Thank you prof.
Commerce? 😆
@@chewinggum5550 why asking me?
Nice explanation
Thank you very much
Thank you!
really thank you professor dave its being easy
from UAE
It was good and clear 🙏🏼🤝
Cause of this vidoe I understant my lesson , thanks very much about that you have like this explanation and share it 👌👌
I am late for this is my first time watching ur video,hope these will help much in future
Hi Prof Dave could you please explain to me as to why the force on the spring is negative?
i think it's because the force of the spring causes an acceleration in the negative direction? i'm not too sure
@@ProfessorDaveExplains true opposite to force applied
thank you!
Great video! This topic is very confusing so thanks very much!
Good job
Amazingly explained
I really like the music at the end of the vids.
Super sir from india in tamil nadu
This is awesome! Thanks
Thanks sir I have made it easy to understand
I be class chilling like i don't care , because professor Dave will explain 😂😂😂
Thanks 🙏
you are a legend of explaining!
2:19 Hooke's Law
Thanks a lot feel benifitted
Thanks professor dave
I Fu*king love this guy
HE IS VERY VERY GREAT YES YOU ARE RIGHT
can't believe bro thought us all of this in 4 min
Now one but our great sir..
Intro best..
He know all about science ❤😘
Cool video. Thank you for your work.
thankyou so muchhh
Great stuff!
4:14 Why is f negative?
Huh Idk 😅😅
At 2:22 you said that force exerted by the spring is always opposite the motion
But while coming towards centre, force and motion are in same direction.

He is forraner Anand KUMAR !!!!👍👍
What about me?
I too need a reply from Dave!
you got it, friend!
He is newton and Jesus at the same time 😀
you are awesome sir. thank u
thank youu
I would like to ask why the force has a negative sign. Is it because it is stretched?
It's acting opposite to the direction of the force we apply, suppose a mass is connected to a spring. We apply the force on the right side, the spring tries to pull us backwards to get back to its natural length. That is, to restore equilibrium. So the force is negitive.
do you have any lectures on carbenes..... but i like your lectures...:):)
california!
Plz make all videos of class 12. We are your greatest fan. So we want to learn physics from you next session it is in class 12
Great!
Explain the chapter system of particles
After many years of searching, I finally found Jesus
3:28 What about the formula for kinetic energy of the spring?
2 hour lecture in 5 min
Sheeeeeesh
I'm arabian and finally I get it thanks for u
amazing content
TEACHER EXPLAIN SMOOTHLY ALSO THATS WHY ITS AMAZING
