What is Acceleration?
HTML-код
- Опубликовано: 7 ноя 2018
- What is Acceleration? Does it mean going really fast? Acceleration in Physics is defined as the rate of change of velocity. Acceleration and retardation are discussed with simple everyday examples! Acceleration due to Gravity is analyzed using the motion of a ball. Uniform Acceleration and Non-Uniform Acceleration are compared.

Ver nice sir thank you so much
Yee true
Q1) (b)-9.8m/sq.s
Q2) a=(v - u)/t v=30m/s
=0.5m/sq.s u=0m/s
t=1minute=60s
Q3) Yes,it is acceleration . Because acceleration is change of
velocity and velocity is speed with direction . As the bee is flying randomly, the direction is changing
. It has a constant speed but not a
constant velocity.
This is the best, most complete explanation of all answers I read. Everybody please watch your annotative symbols; many answers had a dash (-) before the numbers! Too troublesome to interpret correct answer; i.e.
i.e. Kaayu Murgeshwari
Thank you sir for this amazing video.
Answer Q.1 (b) -9.8m/s²
Answer Q.2 0.5 m/s²
Answer Q.3 Yes, It is an accelerated motion as it's not travelling in straight path and its an example of non uniform Acceleration and Acceleration is rate of change of velocity. It is randomly flying.
Thank you sir❤ Please come up with Doubt Classes In RUclips.
I like teachers teaching and showing practical examples
Thanks for liking
Mee too😎😎
I too....

Me too.......
1- 2nd option because of retardation means -ve
2- 0.5m/s.s
3- yes, due to change in velocity...
Thanks
1. -9.8m/s2
2. 0.5m/s2
3. Yes it is accelerated motion because the velocity is not constant and the direction will not change
Sorry no1 = 0m/s2
3: is changing the direction
Top 3 questions answers-
1) - 9.8 m/sec² since this case is retardation.
2) 0.5 m/sec².
3) yes it's accelerated motion since the velocity is changing here. We know that Acceleration is rate of change of velocity.
Sir would you please check my answers?
No
1 ans is -9.8 m/s square
2 ans is a=30-0/60=0.5 m/s square
3 ans yes because the bee is flying by changing its direction.
Super! All your answers are correct :) Also try the Quiz for this video on my Website. Quiz button is below the video: www.manochaacademy.com/physics/motion/l/what-is-acceleration
@@ManochaAcademy Your explanation is outstanding. Keep teaching us such a splendid way with more and more topics.
I would like to say...that I tried to understand a lot from my teacher and many other you tube videos....but I was not able to understand acceleration at all....but sir you have made it crystally clear...thank you sir a lot lot lot....may you always make such useful videos for our help ...thanks a lot
It's my pleasure
Same to me!
Me too
Sir ko kitna saara pyaar du samjah ni aa rha yr maine 5 I'd se subscribe kr diya love u sir asap jaisa teacher har jagah ho to bache 9th me top karenge top
Same like me i always learn acceleration velocity from last 3 year but didn't get the idea about this thanks a lot make the more videos in such manner practically humble request
thank you sir, u cleared the pending doubts of last 10 years
You are most welcome
1. B , 2. 0.5m/s^2 , 3. The bee is in accelerated motion. Because of change in direction of the bee (randomly)
Ans1; -9.8m/s²
Ans2; 0.5m/s²
Ans3; It is in accelerated motion with changing velocity in every direction.
1st answer
The value of acceleration of a ball is -9.8m/s² because the ball's speed is decreasing due to earth's gravity. So,it is a case of retardation while when ball is goes down it's speed is increases so that is the case of acceleration.
2nd answer
Initial velocity of a car is = 0m/s
Final velocity of a car is = 30m/s
So, Acceleration = Change of Velocity÷Time
a = (v-u)÷t
a = (30-0)m/s÷60s
a = 30 m/s ÷60s
a = 0.5m/s²
3rd answer
Bee is randomly moving in a room at a speed of 1m/s. It means bee is not changing it's speed that's why it's speed is constant. But it is changing it's direction because it is randomly moving in a room . So, bee is changing it's direction that means it is changing it's velocity .
And Acceleration is a rate of change of velocity so, this is accelerated motion
And finally sir you are a great teacher and your explanation are too good
Great job annayaa
1. B
2. 0.5 m/s^2
3. Since it is moving randomly, its direction is changing as well. But the point is speed/velocity is the same. I think it is accelerated motion. Quite tricky though🤔
2) 0.5 m/square
3) It is an accelerated motion because as the velocity is constant but it direction is random and as the velocity is a Vector quantity , the change in the direction of the bee cause in change in velocity and hence it is an accelerated motion..
what about the first question
@@owamink I think it should be g- a🤔
1.(b) -9.8
2 .=30/60=0.5m/s^2
3.yes because of the change in direction= change in velocity=acceleration
Crt 😎
Your all question is right bro
Q1 answer -9.8m/s*2
Q2 answer 0.5 m/s*2
Q3 answer yes,bee is in accelerated motion because it's changing its direction with speed 1m/s. As we know we can change acceleration by changing direction.
Thank you sir
You are wrong kid

Sir how to see your all physics class vedios....sir i see vedios in playlist only 5 ..pls add vedios in playlist
If you want to see all Physics videos, you can go www.manochaacademy.com. The 2nd row has the Physics videos.
Thanks for your feedback :) Yes, I'll add a Physics playlist in RUclips!
HW..
1. b.-9.8m/s^2
2. 0.5m/s^2
3. It is accelerated motion as it moves randomly.Change in direction can result in change in velocity, thus leading to acceleration
but its actualy speed
Q.1)Ans- (-9.8)m/s²
Q.2)Ans-u =0m/s
v=30m/s
t = 1min=60 sec
a=v-u/t
a= (30-0)m/s /60s
a=0.5m/s²
Q.3)Ans- No, it is not in accelerated motion as velocity is speed with direction.
Let the speed is constant which is 1m/s but the bee is flying randomly means changing its direction. So, it is not accelerated motion.
1) b)-9.8 m/s squared
2) 1/2 m/s squared
3) yes. Because though it's speed is constant, it's direction is random. So it is accelerated motion.
Please tell me sir if the answers are correct
Thank you sir 🙏🙏🙏
You are explaining awesome sir.
Thanks
Sir because of u I transshipment my studies I am weak in physics firstly but now what a magic because of Ur superior teaching I figure out and improve my self a lot . I know so many students like me change because of this superior teaching I hope sir u were my school physics teacher.
It's my pleasure
Sir
1st ans is option"b"
2nd one is 1/2 or 0.5
3rd ans:it is accelerating , because it is not travelling in a straight path rather it was going randomly.
Sir thanks, sir. I wanted to study physics with the best visualisation and with concept clarity. Even though the byjus app gives us animation, you teach not with animation but with the real world. And it will also be easier to understand as you are using the objects that we use in daily life to illustrate. I am from a poor background, sir. And I wanted to learn physics like this but in tuitions, they will charge big amounts. sir no words to say your effort for teaching. I love it. Don't stop teaching at any point. You are doing one of the holy jobs on the planet. And answers for the top 3 questions
1) b. 9.80ms^-2
2). 0.5 ms^-2
3). The bee is accelerated because displacement is a speed in single direction or a line. If we take any point in the line we can see that the velocity will be different because the bee is randomly moving round the room. Which in turn affects the velocity. And it may not be accelerated if it's inittial and final position is same. Because, then the displacement will be zero. I was stuck at this chapter for a day. Then I found you. Probably the best find in my life.👍
I've never felt better about Physics Ever....
I've never seen a teacher that explains stuff in such a fun manner
This man deserves a reward...
So I'm gonna dissaper and u can solve this **snaps**
**Appears in a different video**
I am blessed to be able to find this video 🙂🙏😌Thank you sir, we actually seek teachers like you.
Answer 1- (b) -9.8m/s^2
Answer 2 - 0.5m/s^2
Answer 3- Yes, it is accelerated motion because bee is flying randomly so it will change its direction, go upward and downward. So in case it is changing its direction chances are that its velocity will decrease, so it is retardation(negative acceleration), if it is coming downward force of gravity is acting on it so it is acceleration.
Thank You for such a nice video😊
Answer. 1 - o m/s^2
We want more teacher like you.... Love from West Bengal
Ans 1) (b) -9.8 m/s^2 (gravity is causing retardation)
Ans 2) 0.5 m/s^2 (a = (30 m/sec - 0 m/sec) / 60 sec)
Ans 3) Yes, it is in accelerated motion because its velocity is changing due to change of direction.
Very Brilliant Idea Sir...I Cloud Never Think That Someone Can Explain Acceleration With A Real Car!!! Really Proud On You Sir.
Question 1: (b) -9.8m/s²
Question 2 : 0.5 m/s²
Question 3: yes it is accelerated motion because bee changes its direction
1)-9.8 m/s^2
2) 0.5 m/s^2
3) Bee has wings so,that wings help bee to move randomly . Here wings accelerate the bee to move .So it is acceleration motion
By Supreet.wale
1)-9.8m/s2
2)0.5m/s2
3)yes ,it is in accelerated motion because its direction changes and there is no constant speed as a result there is a change in velocity. Due to change in velocity it is in accelerated motion.
Excellent!! All your answers are correct :)
Q3, even though bee is going at constant speed of 1 m/s since direction is changing it is still considered accelerated motion. Since velocity is changing with the direction change.
Ohhh k sir tqqq. Ur way of teaching is excellent. I have understood the concept very well.
Great to hear that :) Thanks a lot!!
1st =(-9.8)m/s²
2nd=30m/s²
3rd=yes because it change his velocity and direction
Q1:- (b) -9.8 m/s*2
2:- 1/2 or 0.5 m/s*2
3:- Yes, because the Direction keep changing , And as we know, changing the direction is the way of accelerating ,
If direction changes then velocity also changes .
im taking online physics for summer since it was full, and the materials are all self-study, this video really helped!
Your study is just like enjoyment
Glad to hear that
@@ManochaAcademy actually it should be glad to read that coz you are reading a comment and thank you for explanation
Q1: option (b) is correct b/c acceleration is caused against to force of gravity.
Q2: vi=0m/s
vf=30m/s
And time=1min=60s
a=30-0/60s
=0.5m/s2
Q3:yes it is accelerated motion b/s it changes its direction.
thanks bro
When I see practical of motion I really remember it forever .
It's you sir who helped me in learning
Glad to hear that
Ans 1. -9.8 m/s²
Ans 2. (30 - 0)m/s / 60s
= 0.5 m/s²
Ans 3. It is an accelerated motion because the velocity of the bee is changes if it flies randomly.
1.-9.8m/s(sq)
2.1/2m/s(sq)
3.accelerated motion
Wish you were my physics teacher in school.
Happy to hear that you liked the video! Do check out more videos at www.manochaacademy.com
@@ManochaAcademy sir please clarify my doubt
Yes u are right
1: -9.8m/s
2: 0.5m/s
3: yes it is in accelerated motion as the bee flying randomly it must be changing the direction and change in direction is change in velocity. *the rate of change in velocity causes acceleration
1.-9.8m/s²
2.0.5 m/s²
3.yes,it's direction changing.
Answers:
1. (b) -9.8m/s^2
2. 0.5m/s^2
3. It is accelerated motion because the velocity is changing with every direction the bee is moving.
1)-9.8
2)0.5 ms-2
3)yes it is accelerated because velocity's direction is changes
My answer also same
I had seen many video before this but ur teaching style and example are made me understood everything ....
Thanks 🙏.....
This is the best explanation ever...imagine if he is yr teacher and he will take us classes outside like this..
well explained sir, , , ,
which camera and all set up u use.. please reply
Sir your teaching is great. I like your explanation very very much.
You explain concepts practically.
Thanks for liking
THANKS a lot sir!
ANS 1= (A) 9.8m/s^2
ANS 2= 0.5m/s^2
ANS 3= Yes, it is accelerated because, its direction is changing.
Wrong 😮
Good practical example. Thank you sir
Sir I have a question on a 60 km track A train travels the first particular metre with a uniform speed of 30 km per hour fast must the train travel the next 30 km per hours so that the average speed 40 km per hour for that entire tips
Woah!!!! Its really amazeous.....ur giving practical examples sir....plz post upcoming videos in practical way sir.....so, all can learn easily....so it will be fair to learn...
My age is 35 and i am seeing his videos to learn something there is no age of learning tq sir for ur wonderful explanation you have Cleared my Doubts
Q1.
-9.8m/s²
Q2.
0.5m/s²
Q3.
Yes, because of change in velocity or particularly direction...
Is it right sir.... Don't forget to tell sir
Q1 is ,B cause it's reverse the direction of gravity
Q2 is 30m/s²
Q3 , yes it in accelerated motion cause it change her direction continuously .
I've been stuck in this lesson for days and after i saw the vid it helped me really thank you ❤❤❤
Saudi Arabia .
1)option (b)
2)1/2=0.5 m/s^2
3)No , because it is clear from the question that it has neither increased nor decreased it's speed.....
#THANKYOU SIR....keep it up for us...😊
3) The bee will be accelerating because its direction is changing, so the velocity will also change and hence, there will be acceleration...
Thank you so much sir for explaining the complicated topics in a practical way to make that easier for students! I wish all the teachers adopt this way to teach in our country!
Ans 1} -9.8 m/s²
Ans 2} a=v-u/t So, 30-0/60
= 30/60 = 0.5 m/s².
Ans 3} Yes, because the bee is continuously doing acceleration i.e. changing its direction.
I am from Bangladesh. I like your videos with practical examples in physics and chemistry. You can also learn how to drive a car.
Ha Ha Thanks
Very good explanation 👍
I understand easily.
Glad it helped
Sir, you know what only because of this topic my whole chapter was not at all strong but only because of you....i got this chapter in a super duper way...Thanks a million...😀👍
1 a(-9.8m/s2)
2( 0.5m/s2)
3 yes because of change in velocity
pls reply sir
You are really an amazing teacher your teaching way is fantastic
1. 9•8 m/s^2
2. 0.5m/s^2
3. It is an accelerated motion, because of the change in its direction.
acceleration will be --9.8 m/s^2 because initial velocity is 9.8 m/s and final velocity is 0 m/s .
and also ball speed is retarding.
--9.8 m/s^2 will be answer if you are talking about acceleration.
this sir is very practical and he should continue this in future too i like this type of teaching
You are the real physics teacher 💕 hats off to you sir 🤘✨✨
Thanks for liking
Q1- ans (b)
Q2- acceleration is 0.5m/s^2
Q3 - yes , as bee is moving so it’s changing it’s direction therefore it is accelerating
Kindly tell is all the answers right or wrong
1ans.(a) 9.8 m/ s^2
2ans.1/2m/s^2
3ans. Yes,it is acceleration motion because it is in random speed
Q1. -9.8 m/s squared. Because the direction is opposite to the gravity.
Q2. 0.5 m/s squared. a=v-u/t putting in the values, 30m/s - 0m/s / 60s which results in 0.5 m/s squared.
Q3. Speed is same but direction is different which means it is an accelerated motion.
Thanks yaar🙂❤️
I love your teaching techniques thanks for this video and create some more videos with pratical example, soon you will reach 10 million milestone.
Live examples are very much necessary to understand physics.Thanku sir
Keep watching
Good explanation...sir
1) -9.8 m/ s^2
2)0.5 m/ s^2
3) change of the velocity
2nd answer should be 2 right ? Because 60 can be divided by 30, because 30×2 = 60,,
Thank you very much sir ❤️ you are practically understand me what acceleration ...keep it up 👍
Thank you sir. I really appreciate your hard work.
Happy to help
Q.1) The right answer is -9.8 m/s^2.
Q.2) Given: u = 0 m/s, v = 30 m/s, t = 1 minute = 60 seconds. Accleration of car = v - u/t = 30 - 0/60 = 30/60 = 0.5 m/s^2.
Q.3) Yes, it is accelerated motion because the bee is flying irregularly and changing its direction.
Sir I have solved the answer tell me that the answer is right or wrong.
G i saw you in the last video as weel
@@lovishdhillon4512 ok
Khota
My guess is that the last one is non uniform motion because even though the bee is flying with a constant speed but we don’t see that its flying in a specific direction. So my guess is its non uniform motion.
Q1-(b)-9.8m/s^2
Q2-1/2m/s^2
Q3-Yes, it is an accelerated motion as there is change in direction of velocity.
1ans- -9.8 m/s^2
2ans 0.5m/s^2
because u= om/s and Vf=30m/s t=1mint= 60 seconds
put the values in formula you will get answer
3ans- velocity is vector quantity its magnitude is equal to speed of the body which is constant in this case
and its direction is changing randomly so in every second the velocity changes 1m/s
hence it is the case of uniform acceleration
1. a) 9.8 m/s²
2. Step By Step solution:
Car starts from rest so the initial velocity will be zero.
'Reaches' means final velocity or final point... Which is 30 m/s.
Time taken is one minute.
Acceleration = v-u/t
By putting the values the answer will be
0.5 m/s²
3. Room is not long... Since it is moving randomly everywhere, it needs to change its direction. We know that velocity is speed with direction. So change in direction also means change in velocity.. so it is in accelerated motion.
Q.1 (b)
Q.2 (1/2m/s)
Q.3(yes , because it changes its velocity with change in direction)
😍
I loved the explanation using practical examples it made it so understandable thank you sir
You are welcome
Wonderful...... Cleared concept very easily
(1) -9.8 m/s^2
(2) 0.5 m/s^2
(3) well yes... acceleration literally is change of velocity*..... and since the bees change their direction, it is an accelerated motion
* = velocity is motion with direction
Hi plz can you tell me the second answer how did come
Loved the way of ellaboration,thanks a lot
Really an awesome elaboration in a lucid way
Your teaching style is very good...you cleared all my doughts..thank you sir
Glad to hear that
Doubts*
This is the way to teach,make it simple with examples,the main aim is to make it understand,Sir,you are good teacher, students studying under you will definitely have lots of benifits plus respect for teaching talent,thanks,God bless you,Sir.
