Alakh Pandey sir lied to us that this is a revision course. but teachers here a teaching from scratch to advance by the way thank u to physics wallah team for making our exams special.

Newton's 4th law : Every book continue to be in rest until and unless internal or external exam appears and speed of page turning is directly proportional to the syllabus to be covered and tension in the mind remains constant

Yes! hitting brakes is acceleration as there is change in velocity(change in magnitude),thus changing the speed.

6:02 yess when we apply breaks the speed deaccelerates which can also be called as negative acceleration . So applying breaks is also acceleration but negative.

We are very lucky that we get a great teacher like Rakshak sir 🤗

Who' forgot the online classes and 😸😸 now' we have physics Whllaa 💖🔥 Wow ....

I am😀 in class 11 and watching this for revising the previous concepts.thanku sir

5:47 yes, applying brakes will also considered as acceleration because acceleration is change in velocity and change in velocity can be brought by changing speed and direction. also, after applying brakes, our vehicle's speed decreases. Therefore, one can say that applying brakes is acceleration.

Yes, applying brake is accelaration. Because, when we apply brakes the speed(magnitude) of the object decreases. A decrease in magnitude means a change in velocity. Hence applying brake is accelaration.

yes applying brake is also a acceleration but the acceleration is on opposite direction and is written with a - sign (minus)

Yes, applying brake is an example of acceleration because through brake it changes magnitude which results in change of velocity and further it changes acceleration

5:58 Yes, applying brake is accelaration. Because, when we apply brakes the speed(magnitude) of the object decreases. A decrease in magnitude means a change in velocity. Hence applying brake is accelaration.

5:40 Yes. When we apply brakes,the velocity is change,that cause change in acceleration.

1st Flim ,,, 7:01 sir vin Diesel vs R.I.P Paul Walker race scene Flim fast and furious My favourite flim ❤️❤️❤️❤️❤️

Yes sir, applying break is acceleration since the velocity is changing when we apply break ( decreasing to be specific)

Sir's "KHATAM" always reminds ME of RAHUL GANDHI.. 😅

Yes, acceleration also occurs when brakes are applied on an object as its velocity decreases to zero.

Sir you are just like your name ...Rakshak ..(a savior of physics )💜💜💜

How many of you are watching in August ,just two weeks before midterm 😅

Aap jaise sir ki yaad hame exam se ek din phele aati hai 😅😅😅

Sir aapki teaching ki vajah se mere saare physics k concepts clear ho rhe h. thank you physics wallah team

Yes sir while applying brake velocity also change and change of velocity is called acceleration💯

in q2 of challenger question by applying 2nd eq of motion we get s2=3s1 solution s1=ut+1/2at^2 putting, s1=1/2×a×100=50a now, u=10a s2=100a+50a=150a therefore we can say that, s2=3s1 I think the correct option of q1 is (a) Thank you sir

5:53 yes break is called acceleration

Yes . Applying breaks of a vehicle is also an acceleration . Because in this velocity changes as it decreases . In this case acceleration is negetive because it's direction is opposite to the direction of velocity .

Yes ,applying breaks is an accelerated motion.This is because in this we chage the magnitude of object.

Yes Sir , When we apply brakes the speed of an object decrease . The Acceleration in this case will be negative .

The three best physics teachers for class 9th: Sanjeev pandey sir (Edumantra 9th) Rakshak sir (physics wallah 9th) Abhishek sir (Vedantu 9th)

Yes, applying brake is an example of negative acceleration (retardation or deceleration) as the magnitude is decreasing and as we already know that change in magnitude of velocity causes acceleration.

8:10 Sir excited to study Rohit Shetty's law of motion 😂 . I hope we will study soon .

Yes if we use the break then also acceleration is available

Yes when we apply brake the acceleration happens because change in velocity the magnitude is decreased it speed has been decreased so that is acceleration

6:01 Yes when brakes are applied there will be acceleration because change in velcocity will change.

Yes sir. When we apply the breaks, we essentially decrease the speed of the car with friction and therefore change velocity. The acceleration in this case would be negtive and is called Deceleration or Retardation.

I have exams today (current time:-12:22 am) i was really not able to do acceleration from 5 days but in more minutes i got it 🦋🦋 thank you so much sir ✨✨

When an object is brought to a stop, such as when applying brakes to a moving object, there is indeed acceleration involved. However, it's important to note that acceleration doesn't just mean speeding up; it also refers to changes in velocity, which includes slowing down (deceleration). In the context of braking, the object is slowing down, which means its velocity is decreasing. Since acceleration is the rate of change of velocity, and the velocity is decreasing, there is indeed acceleration occurring during braking. This deceleration (or negative acceleration) is caused by the force applied by the brakes, which reduces the object's velocity until it comes to a stop.

Yes because when we apply the brake the speed changes to zero. Acceleration is change in velocity

The way he just calculates the answer in his mind is just amazing,,, shows his experience

Answer yes when velocity change its called acceleration.

6:30 Actor:. Vin Diesel Movie:. Fast and furious Can i gat 1 like ple

Best teacher ever really

Yes sir applying break is also acceleration because magnitude is changing

5:42 yes because the car will come to rest this will change the magnitude of the velocity and body accelerate

Yes if we put break it will decrease the speed and it is rate of change in velocity.. Hence it can change magnitude and it is acceleration 5.57

This is the best channel for class 9 Physics,I recommend every class 9 student to watch this channel especially for physics

1. A- POLE 1 & POLE 2 2. B- S2=3S1

Yes, when we apply brakes it cause a change in the magnitude of velocity ,so it is acceleration

yes, applying break the magnitude of a vehicle can be changed so velocity automatically changes

We are very lucky that we get a teacher like Rakshak Sir

Sir u r the best teacher of physics🤩🤩✨🙏

Love the way u r teaching ....... mujhe apna syllabus 1 month me khatam karna tha or aapka ye chanel aagya ......thank you 😇😇😇😇

You are a good teacher

Love you saying "school wali madam gussa hogi"

Yes when we apply brakes the change in velocity occurs

Thank you sir u are the real God for me because u have clear all my doubt in physics you help me a lot not me only but all the students who study physics from u

Yes, applying breaks is Acceleration because when we apply breaks there is change in magnitude and it changes velocity that's why applying breaks is acceleration

Yes sir if brakes are applied than it known as acceleration of decreasing velocity which is known as DECELERATION

5:52 answer is yes when brake is applied then the velocity is change then the acceleration is also be change

yes sir, when we apply break a velocity of moving body decreases with time, the acceleration is said to be negative acceleration or retardation

Yes it's correct, acceleration is velocity because we applied brakes on an object, the object are stop so that's called acceleration

8:14 Rohit Shetty law of motion 😀😀😂😁😁😁😂😂😂

Bhai comment Karo jinke school me gravitation bhi khatam ho gya or yaha motion bhi samaj nhi aya 😂😂

Yes, when we apply break then, speed is less/ and velocity is change. So, it is acceleration.

Awesome Thanks again…. For this amazing lecture

Yes, applying brake means acceleration as when we apply brakes our speed decreases and as we know velocity is speed with direction and any change in the speed or direction, cause the change in velocity and thus producing acceleration.

Answer of Challenger question 1 - A) Because velocity is increasing constantly because of acceleration until the car reaches 4 pole . So lesser the velocity , the more the time taken to travel

Sir you have committed a mistake here 20:00 , Question demands is in other way,i.e., asking retardation, so the answer must be in +ve ,.i.e, 1m/s². Your answer would be correct when the question demands is for acceleration,.ie., -1m/s².

Yes ,offcourse sir, there is a acceleration when we apply breaks due to which magnitude decreases.

Everyone: writing wonderful comments Leh me : searching the name of movie in comment section which sir told 🗿

Yes, Pressing break is acceleration because change in velocity is acceleration either decrease or increase in case of applying brake velocity in is dethe velocity is decreasing that's why applying brake is acceleration

This is my first physics class where I don't get bored

yes braking is a type of acceleration because velocity is changing

I want these type of teachers in my school they are so good I was not able to understand this in school but now I got it thanks to you sir 💜💜

Why no one talking about sir's tshirt 😅 😂

.to apply break is to decrease acceleration i.e in negative acceleration.

Best physics teacher so far ... finished my school n college but never found somebody with so amazing teaching skills.

Sir thank a lot bcz other platforms always provide this type of lectures by money and even notes. But i like this series by deep of my heart

well explained sir !! thank u it helped in exams alot ☺🙏

Best best best teacher every 😊 salute to this teacher and this channel. Who helped me a lot in science. Love from heart.❤. My all credit of marks will go to you

Answers of NTSE numericals:- 1) pole 1 and 2 2) S2=3S1

Thanks sir for clearing the concept of equations of motion.

You are the best teacher in physics 👏 🎉🎉🎉🎉

48:42 Alakh sir be like - na na na itni chaiye kaun banbayega🤣🤣😂😂

Yes sir, applying breaks are also acceleration because it change the magnitude of velocity of the object.

yes, application of break is acceleration because when break is applied speed (velocity) is change that is rate of change of velocity is acceleration wonderful session sir✌

thank you sir Alakh Pandey for giving us the best sir on the RU-vid channel to learn physics Love from Pakistan

6:00 Yes applying brake is a negative acceleration

at 6:59 movie = The Fast and the Furious: Tokyo Drift

Challenges. 1. d) pole 1 and pole 2

5:46 Yes, applying brake is also acceleration as we are bringing change in the velocity of the vehicle...

yes when we use brake then speed (magnitude) changes and so velocity changes....and braking can also be retardation

When We apply brakes in automobile then Velocity is also changed.

5:46 ha Acceleration hai kyunki speed change hone ko Acceleration kehte hai aur yaha speed change ho rahi hai to yaha Acceleration lag rahi hai 🥲🙂

Yes, applying brake is also a acceleration because when apply brake speed is decreased that why applying brake is acceleration

Yes, sir, braking is also an acceleration.

5:50 If we apply brakes then velocity will change and acceleration is exactly the change in velocity . So yes.

Yes sir brake lagana acceration he because ap 45km/h speed me bike chala rahe ho aur aap ne brake mara to speed suddenly Kam ho gayi

Best teacher in the world as far as physics is concerned
