Would be nice to mention that, even if both the surface and the object were perfectly smooth (Which would cause no friction), the particles such as plain air would still, while very slowly, eventually cause enough friction to completely stop the object. It is also impossible to create a vacuum with no particles in it.

Ma'am you are an excellent teacher. All of your videos are very informative. .Don't Memorise is one of the best channel for educational videos. Kindly, may I know your name, please?
Summary of this video Wow ! So there are 2 factors affecting friction :- 1.The nature of the 2 surfaces in contact :- whether they are rough or whether they are Smooth Smoother surface :- lesser friction Rough surface :- more friction Reason :- Irregularities in form of grooves and ridges ! 2.The force with which the 2 surfaces are pressed together . Also depends on the mass of an object for eg :- a 5 kg ball will move slowly cause it applys more force on the surface but a 2 kg ball will move faster because it doesn't press down much on the surface 😉
Friction also depends on the area of the surface being in contact with another. Like an object with wheels is easier to move than an object without. Tha air also makes a difference in the friction on an object, if an object has more surface area in contact with the object the more friction and vice-versa.
I was watching this before my exam and it helped me a lot because I before thought it was difficult, now it is very easy for me now. THANK YOU SO MUCH ma'am

Just a question related to friction. If there's no friction on the surface and we take a ball and try moving it on the frictionless surface. Will it roll or slide? If it will slide then is friction needed for a object to roll?

I am a subscriber of yours. I have analyzed a few RUclips channels and found that in comparison, you still have quite little number of subscribers, say (1/10)th subscribers of those channels which publish videos of same level as of yours. Also, a few amateur informational video publishers on RUclips, with far less number of published videos than yours, have about as many subscribers as you have or have more than half of the subscribers that you are having presently (I am talking about those amateur video publishers who publish hand written content, related to elementary studies or college level studies and are steadily posting videos from at-least 2 years). In short, I wish you had more subscribers because your content is just "excellent" and your lessons are also very easy to understand. I really appreciate your efforts and hope you get more subscriptions soon. I found your channel to be very beneficial. Keep up!
Thank you so much Aakash! Yes, we agree with you. We're just trying our best to create quality content, and we're happy some subscribers like you appreciate it. Hope to touch the 100k mark by October :)
"As a result, we get the rule of linear fast defense and angles of angular momentum, respectively, because space is homogeneous and equinoxic. Because of the time being, we get the rule of energy conservation." Can you explain ?
4:02 but even without friction, the brick with the lighter mass would still reach a greater distance right (in accordance to the second law of motion where mass and acceleration are inversely proportional)?
Some of the energy during friction will transfer into heat right? Does this mean that every time an object has friction it will loose atoms and become lighter?
Yes, for example if you rub a chalk on a rough surface it loses some particles. The same applies for others objects too in some objects like the one made of iron or any other strong material it will lose particles in a very small amount. If a hard object is rubbed on a surface for a long time the change will be noticeable.
But we learnt in school (Grade 11) That friction is caused by molecular forces of attraction, not the interlocking of hills&Valleys. Also we learnt that smoother surfaces have more friction than rough surfaces. Can you Please explain these two things??
Thank you. I have a hard time memorizing science now you made me understand to understand and visualize it not memorize it. I hope I will get a perfect score on the test.
The channel name Suites a lot and actually I used to memorise but due to ur channel I don't memorise I try to understand what it's saying and ur concepts r amazing🤗🤗
plz can you allow us to download the videos because here is no download option plz display the link of download of these videos because these videos are very helpful and w shoud be able to watch them anytime offline!!!!
but wait mam according to modern view friction occurs due to cold welding between molecules that are in contact of both the surfaces so pls do teach modern view also
The last part on weight made me think of a question. In zero gravity (like in the ISS) does that mean that an astronaut throwing a tennis ball or a brick with the same force would go the same speed?

Take blacktop and chemically adjust to blending car tires will lesson the friction of the car tire
Summary of this video
Wow ! So there are 2 factors affecting friction :-
1.The nature of the 2 surfaces in contact :- whether they are rough or whether they are Smooth
Smoother surface :- lesser friction
Rough surface :- more friction
Reason :- Irregularities in form of grooves and ridges !
2.The force with which the 2 surfaces are pressed together . Also depends on the mass of an object for eg :- a 5 kg ball will move slowly cause it applys more force on the surface but a 2 kg ball will move faster because it doesn't press down much on the surface 😉
Definately one day will I get good Marks in physics because of u❤🤩
4:40 can we also say that the amount of force applied is also a factor? Pls reply ASAP
Yes we can say that but that will be the weight of the object itself
Well done ma'am...
Thank you
Tnx!!!
Can u also pls explain normal force & weight? I don't get their difference.
force starts with f and weight starts with w
@@cacalightx Omg thank you!!
Friction also depends on the area of the surface being in contact with another. Like an object with wheels is easier to move than an object without. Tha air also makes a difference in the friction on an object, if an object has more surface area in contact with the object the more friction and vice-versa.
forced of friction is independent of area.
Nope , Friction force =coefficient of friction X Normal force. Therefore it's area independent.
Also rolling friction is different

4:02 but even without friction, the brick with the lighter mass would still reach a greater distance right (in accordance to the second law of motion where mass and acceleration are inversely proportional)?
yes but it would slide forever until a wall or any barrier blocks it then it would slide the other way hit the wall again and so on
@@yllaw2161 oh true
That’s tru but acceleration also depends on friction if there was no friction then….they both would move at the same speed…and go on infinitely….😁
Thank you ❤️

Very nice all doughts clear
But we learnt in school (Grade 11) That friction is caused by molecular forces of attraction, not the interlocking of hills&Valleys. Also we learnt that smoother surfaces have more friction than rough surfaces. Can you Please explain these two things??
It is because of adhesion which means sticking ,when two smooth surfaces are bring together they stick with each other by making bonds,
It was too helpful for my exams
