In this Mission Mid-Term series, your favourite BYJU’S educator, Saurabh Sir, revises important concepts and formulas in your class 9 Science chapter 9, Force and Laws of Motion.
Some of the topics discussed in this class are as follows:
1. Newton’s Laws of Motion
2. Conservation of Momentum
3. Inertia and Mass
4. Balanced and Unbalanced Forces
The natural tendency of objects to resist a change in their state of rest or of uniform motion is called inertia. Further, the sum of momenta of the two objects before they collide is equal to the sum of momenta after the collision given that there is no external unbalanced force acting on them. This is known as the law of conservation of momentum. Join this class to learn more about force and laws of motion.

Newton's fourth law of motion 😂😂:-
Every book continues to be in state of rest and covered with dust until and unless internal and external exam appears and the speed of page turning is directly proportional to the syllabus to be covered and tension in mind remain constant .
😂😂
😂
🤣🤣🥲
🤣🤣
😂😂
Lesson starts at 8:41
tq
Thank you
Who skip 5-6 minutes in every video 😂😂
not five to six minutes, half of the video is of promotion and stuff...
I watch sessions of sir in 1.25x speed 😂😂🤣 who else
I watch in 1.5x speed
Bruh he speaks so slow. I watch it in 2×.
From now after reading your comment me too 🤣🤣🤣
I watch in 2x
I watch in 1.75x
inertia ex : us sleeping and still want to stay at the state of rest but external force (mummy ka thappad to be specific
)is applied which makes us moving
😅😅😅😅😅😅😅😅😂😂😂😂😂😂😂😂😂😹😹😹😹😹😹😹😹😹🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
just wanna say that; in such one shot sessions, please dont't interact with the live chats. it actually wastes time.
i just understood the entire chapter very clearly....thank you sir and byjus
My all doubts are cleared in this session, thank you Byju's.
Hello Keshree, Glad it was helpful! stay tuned for more such sessions🤗
Muje laga carpet par dust particles ko dard lagta he isliye gir jata he😅
Sir can show the chats what they telling or saying because you read question in mind , then you talk to them , we can't understand what you are telling
This 1shot season is very helpful sir!!
Hello Sadhana, Glad to hear that! Keep Watching and Keep Learning😊
thank you byju's for understanding this physics chapter this much easy you are the only one who can help us for feature learning
Best teacher i ever seen
Thank you byju's classes !!!
In my school there is a physics teacher named saurabh sir 😅 all saurabh sir teaches well
Direction
Dear Sir,
I just wanted to say a huge thank you for making physics so much easier for me. I used to struggle and cram just to get through it, but your clear explanations and engaging teaching have changed all that. Now, I actually enjoy learning and remembering the concepts we cover in class.
Your passion and dedication have made a big difference in my academic journey, and I’m truly grateful for all your help.
Thank you so much!
thankyou sir can really understand very well
superb 😃😃👏👏👏👏
धन्यवाद
Good evening sir
Its so helpful for me ......even i am not very good in physics.....but after listening and see this video i think i can became very goood in physics 😊😊thank u so much byju's

😂
Thanks sir I understand every well thank you byjus
I am watching this one day before my exams 😅
Thank you so much sir you are the best teacher and thank you byjus 😌😊🙏
Hi sir🎉
sir you explained inertia of motion ,inertia of rest , inertia of diection but what is the defination of inertia sir plz reply
Property of body which allows it or inclines to maintain its state!
Friction
Me watching before my exams 😂😂
Force and laws of motion
And I will tell my friends to also watch the byjus
Thank u sir
Yes
Galileo
Inertia of motion
It was Very helpful Thank you
Never thought I would understand physics so well thanks to byjus
It is clear sir
Hai Shiva, Glad to hear that, Keep learning with us😊
class was awesome
Sir can you please cover work and Energy
How many law of motion of Newton in all
3😊
@@user-zi8jx1bd3g thank you bro
❤
From sanjana
Force have magnitude
Your class is amazing but in 50 miniutes class 10 minutes for Advetersment
Newton
❤❤❤
This lesson is pretty well explained
Thanks sir

Okay but you're my fav teacher here
Never thought I would understand physics so well
Thank you byjus :)
Hello Axel, Glad to hear that, Keep Learning with us😊
This chapter was very hard for me but after the class I felt like this is not the thing which my teacher thought me
It's better to learn here in very deep manner Thank you Very much!!
I have master in this chapter 💖☺❤
You're welcome Chaitali😊, Keep Watching and Keep Learning!
Who all are seeing this video just before the exam
I am having my exam today bro
😂😂😂😂
What is your name
External forces' qct on it
Sir Issac Newton
👍
Thank
Sir good evening
😢
Who are series video in
2024
I watch the session of sir in 1.5x😂😂😂😂 speed who watch else
What is inertia in one word
Inability
Hi
hi sir
larger the mass larger inertia
Good Mirza, Stay tuned to our Channel for further updates on upcoming Amazing Sessions 😊

Nice chapter
Nice chapter
English ma na

I also skip 5 to 6 mins
sir ur hair is not visible
Ayo what💀
💀
🤣🤣🤣🤣🤣🤣🤣
3 min to video age bhadaya h
I want in Telugu
What are you teaching😢😢
Hes overacting too much and answering unnecessary live chat’s instead of actual studying
