Byju's teacher are best ❤😊 Because they are very hard working person 😊😊❤❤. Byju's is the besttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttțtttttttttttttttttttttttttttttttttttttttttttțtttttttt❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
Sir nice explanation thank you sir this English teaching is useful all over India but Hindi teaching is only meant for Northern parts only so try to explain in English sir thank you

@@SHAZAIN.11 yeah? ig
4:15 class starts
Thanks 😂
Ok
onense opon thime therr was a boy
Thanks
Thx bro
5:55 true 👌
9:03 with different velocity
9:19 to increase or decrease smoothness comparison of the friction
4:47 Rolling Friction
anyone here in 2024
yes i am
hmm
Namaste 😅
Mee ❣️
💀
4:18 class started
19:46 thanks for extra knowledge able
Byjus teachers are best
Bro magnet brains is also best 💪
Phisics Wallah is more best than magnet brains and byjus......

Adhesion meaning- The tendency of different molecules to attract each other, causing materials and objects to stick together
thanks
Really! You all just made my day♥️♥️♥️
Thanks a lot for liking the session Shambhavi🤩 Keep watching!
41:44 in short, front wheel is receiving friction and rear is applying friction
Sir more than teaching you are answering those children 😢
Sir actually your teaching is excellent
True
it is a recoded live steam
It is their responsibility to answer them and it is also additional information for us
So please try to be happy
thank you sir for this video 😊😊😊
Most welcome Bhavesh😊 Keep watching!!
Any one making notes 👇🏻

thankyou very much byjus!

Sir why the friction was there in forward if the real wheel was moving forward?
wheel is pushing the ground backwards, that's why the wheel is moving foreword.
I know the person who has asked the question is now in class 9 but this answer is for those who don't know
the cycle is running without a chain
39:10 ghumna hota hai😂😂😂😂😂
Sir both are true 6:23
Sir I like ur classes and I am a subscriber of byjus I also attend live byjus classes why don't u come and teach us in our regular classes sir
I can't understand how the friction of rear wheel is in forward🤔🤔🤔
33:52
Friction between road and bicycle
30:52 static
😊
15:05 more the weight more will be the friction😅
Thank you sir, fell in love with your teaching style
😮
13:06 to increase decrease frition
5:56 False
Thanks sir for this wonderfull explanation❤😊
True
15:44 w = mg
Weight= mass × acc. due to gravity
No, every teacher are. Best all channels
18:31
Because it has smooth surface
4:19 class start 😂😂😂
Up down shaking byju's teachers rocking💯🔥
class starts 4:20
"Quantum stabilized atom mirror" is found to be the smoothest solid surface as flat, rigid, perfectly smooth
11:13 thanks sir I am yesha shah your subscriber....
Name any object which have a '0' percent of friction
Class Start at 4:19
13:55 smoth surface less friction
but when both hand are moving together the friction acting on them is fluid friction
How
Thanks a lot
Most welcome Bhawana🤩
Byju's teacher are best ❤😊 Because they are very hard working person 😊😊❤❤.
Byju's is the besttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttțtttttttttttttttttttttttttttttttttttttttttttțtttttttt❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
According to me saurabh sir are best 👍👍👍💯💯💯💯😊😊😊😊❤❤❤
There are no many shourabh sir
Here is only shourabh sir😂
It's used for respect
Try to obey people
Don't tell me to "how to obey elders okay" I know better then you
4:52 opposite direction
Thanks sir
Welcome Rupesh🤩
Sir Mithlesh here
4:20 is when the sesssion starts with the chapter
6:00 true
friction causes heat and air pressure
Sir 6chapter 🎉🎉
24:28
🔝🔝🔝physics class ever I seen in the world 🌍
8:42 static friction?
Please eat something yellow in color and semi-solid in consistency.
Soo good ty soo much
Sir aap bhout accha padha te ho
true
Thank you byju's for your hard work 🎉❤😊
Sir the friction exerted on rear wheel is apposite to motion not from the direction of motion
Sir .your answer is right. And Sorry for my reply. You teaches the best
Sir nice explanation thank you sir this English teaching is useful all over India but Hindi teaching is only meant for Northern parts only so try to explain in English sir thank you
Thank you sir for clearing my doubt
mujhe joh doubt rehta hai sub ye video dekh ke clear hoj ata hai

Heehee
10:03 sir I have a doubt what about the mirror ?
Hi 14:19
best teacher for physics in byju
Thank you sir for giving wonderful explanation.I got full marks in physics. thank you for good explanation and your best wishes forehead also ❤️❤️❤️🥰🥰
Thanks a lot byjuse teachers🎉🎉🎉🎉🎉🎉🎉🎉
Sir back wheel also move forward
4:20 / 52:37 class start
Sir you are the best teacher
Sir your best ❤u explain very well ❤❤😊
1 like = 1 hour study
Please study atleast 1 hour from my side😂😂
Best physics teacher in byjus

Great explanation
Thanks
Welcome Riyaz🙌
Sir ur teaching is really amazing

ddddddd
👍👍A great session
Byjus is always best👍👍
Best way to study --Byju's
Keep it up 👍👍👍👍👍👍
Thanks a lot Ananya😍 Glad you shared your thoughts! Keep watching!
sir why old bags have 2 wheels and nowadays they have 4 wheels why and how it is helpful
13:14
nice explanation
Sliding friction
Exam is near
nothing is clear
dont worry
when Byjus is here.
