Friction is non-conservative force I.e. the energy spent to overcome friction is lost to the surroundings as heat.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.
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 😉
I hate when someone become topper because they memorised all the maths question in workbook teachers should give questions out of book in maths to test conceptions , creativity , logic instead of memory

That’s really helpful ! Thanks sooo much to your videos , it really helped me understand these confusing thingies for my test tomorrow ! Continue with the good work 😍🌷👍🏻🔥

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

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🤗🤗
thank you so much..your videos are so helpful. for me i didn't took physics and now i'm struggling in our current course, however, your videos and explanation made it easy!! So Thank you!!
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??
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 UA-cam 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 UA-cam, 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 ?
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.
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!!!!
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.
You're most welcome. We are glad that you understood the concept. We are happy that we could help you learn. Do support us by subscribing to our channel. 👍👍
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?

Friction: Am I a joke to you?
Haha
Bro that's the reason why he used to do it on a smoother surface making it easier to do it bcuz of less Friction force

btw space is a vacuum

@@shanemu125 No, it is not a true vacuum.

Very deeply explained thanks mam

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

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,
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?

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….😁
