Hello mam
I am Mansi
Mam here are my questions
1) Mam kya extension spring balance automatic hota hai
2)Mam what is the definition of rolling friction
3) Mam laws of static friction kya hota hai
Mam kal mera test hai toh please bata dijiye😊😌
Mam mujhe pata hi nahi tha ki aap maths ke sath sath science bhi padate hain aur bahut achha explain karte hain aap
Wish you a happy teacher's day mam
Kyuki aaj teacher's day bhi hai na aur aap teacher hi toh ho
Wish you a happiest teacher's day ever

Ma'am I had one doubt, in the previous chapter we had learnt that when two forces act on an object in different direction but are exerting the same force, the object does not move. So here, does it mean that the amount of force we are exerting on the object will be equal to the force of friction that is exerting on the same object in the different direction? That is why the object stops moving? Sorry for the long question.

[prachiverma]

Ma'am please teach us physics through 3D images by showing us not just by explaining.

[frogy_life]

Ma'am hardness pe bhi friction depend karta hai kya??? Like steel with same weight produce more energy(friction) than wood

[vanitandon]

watched 8 hours 20 minutes before exam and this video helped me a lot in exam

[ටPSYCHOGURLට]

Mam what is the simple defination of friction

[ayfun]

Who are the students of 2023-24 batch who are watching this video..

[Jinwoo_]

Mam 9:15 vo rolling friction hoga sliding nahi kyuki cycle mein wheels hoti hai aur vo roll krti hai ❤

[santoshtripathi]

mam to apply friction the surface and the object both should have rough surface then only the friction will be applied right??

[neetuchoudhary]

Thx mam for this explanation on 14 there is my science exam it helps me so much..✌️

[khushibaranwal]

Ma'am tell me please that when we rubbing hands then friction increase or reduce

[sonamrohela]

Mam this is very helpful video...
Keep it up magnet brains....
God bless you...

[aariz_]

Teracher with respect I agree with you but if roughness is friction than how come two smooth surfaces are having so much friction example- glass sheet is there in a very smooth rubber disc but glass is pretty smooth and rubber is also very smooth
Plz explain

[ujgamer]

28:16 i found mistake


Spikes also slip on smooth floor

[biroispiro]

Mam your explanation was great....I will complete my syllabus to the help of your video's thanks mam and magnet brains.🙂

[taanyamothia]

Thank you mam for your excellent explanation of this chapter tomorrow is my exam and this video is very helpful for me

[PremSinghParihar_]

Thank u for this lecture.
Is there any pdf of the notes? If yes how can i access them?

[SiyaPahel-Jain.]

Thank-you mam...for nice explanation...😇😇
