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

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
here are my answers:- Q1, (b) Q2, 0.5 m/s^2 Q3 Yes because the change in direction is considered a change in velocity even if there is no change in magnitude. You made this concept so much easier, thank you sir
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
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.👍
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
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🤔
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
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?
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
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😊
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..
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 TH-cam.
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**

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.
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...😊
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.
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
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 .
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.
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 .
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.
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
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...😀👍
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.
Oues 1= -9.8 m/s per square Oues 2= a=v-u/t Initial velocity =0 Final velocity =30m/s Time=1min = 60 sec a=(30-0)/60 Ans = 0.5 Oues3=No,it is not accelerated motion beacause speed 1m/s is constant but direction is not constant
Bhai 3rd ka ans.... Bhi yes hoga... Kyuki bee randomly roam kr rhi n.... So it would change it's direction too.... And if direction is changing velocity is changing which in turn results in accelerated motion..... 🙂🙂🙂
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.
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
Q1.) B. - 9.8 m/s^ Q2.) U = 0 m/s ..V = 30 m/s ..T= 1min a = v - u ÷ t = (30 - 0) m/s ÷ 60 = 1/2 = 0.5 m/s^ Q3.) Yes , it is an example of acceleration as the direction of the flying bee is changing ..!
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.
You have taken great effort to make us understand the basic concepts. As a father, I was able to understand your explanation and help my daughter to do the same
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
Hello Sir... hope you're doing absolutely great. Thank you so much for such an amazing content.😇 This is one of your old students who is following you since Grade-9 and now I'm in Grade-11. Sir, I have honestly always loved your videos and your way of clarifying the concepts. I really request you to kindly start uploading videos for 11th Science. Would be of great help, Sir. Please consider this request and start uploading as per time permits. 😊🙏 Hoping for a reply.
Q1) ans= -9.8m/s^2 Because, when we thrown the ball upward there's retardation means decreasing The acceleration means negative acceleration so it is- 9.8m/s^2 Q)2 ans= (u)=0m/s (v)=30m/s (t)=1 min = 60 sec a=v-u/t =30-0/60= 30/60=1/2=_0.5m/s^2_ Q3)ans= it is accelerated motion because, 🐝 bee is flying randomly but it changes it's direction and it's velocity is constant hence bee is in accelerated Motion........ 👌👌👌👌👌Thanks sir for understanding me very clearly and nicely really sir you are great ,sir one boy or girl commented you that plz talk in Hindi but sir when you talk in English then we will understand it More clearly thanks sir.....🙏🙏🙏🙏
Brother ... velocity is change in speed and "direction" and we know that if velocity is same or constant then acceleration is 0 ...... but the given question direction is not same so velocity is not constant that is why 🐝 bee is in accelerated motion ....❤️ Your answer is correct but your explanation is kind wrong 😅🙏🏻👍
Sir bundles of tnks from a years we studying only theory thats why we not understanding clearly,practical work is one of the best work and now my concept become clear to watch this video ,sir you are the great person.May an evil eyes not affected ❤❤❤❤❤❤😊😊🤗🤗🤗
thank you sir Q1] 0m/s^2 Q2] 0.5m/s^2 Q3] YES, it is accelerated motion because the bee is moving randomly that means u and v are not constant and[ the bee is applying force to move]* additional
Q.1 Ans:since the ball is thrown upwards it reduces it's speed also known as retardation and since no data is provided it's value will be 0m/s²that is option (c)..... Q.2 Ans:0.5m/s² Q.3 Ans:no the bee is maintain a constant speed but the bee changes it's direction so it is accelerating... That's just my understanding and pls correct me if I'm wrong ✌️✌️ And yeah thanks for the video need more videos related to this subject that is physics ♥️ Thank you 😊
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.
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.
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.

thank you sir, u cleared the pending doubts of last 10 years
You are most welcome
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🤔
"That's right" this word encourages us to give answers more!
Yes
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

t = 1min=60 sec
a=v-u/t
a= (30-0)m/s /60s

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.
Oues 1= -9.8 m/s per square
Oues 2= a=v-u/t
Initial velocity =0
Final velocity =30m/s

@@princypatil3270 Thanks
@@user-anhat07 you are welcome 🤝🤝
well explained sir, , , ,
which camera and all set up u use.. please reply
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.
I am blessed to be able to find this video 🙂🙏😌Thank you sir, we actually seek teachers like you.
You have taken great effort to make us understand the basic concepts. As a father, I was able to understand your explanation and help my daughter to do the same
Glad to hear that.
Thankyou sir , you are really best.
Most welcome
I UNDERSTOOD EVERYTHING ABOUT ACCELERATION FROM THIS VIDEO...VERY GOOD EXPLAINING SIR.THANK YOU
You are most welcome
I loved the explanation using practical examples it made it so understandable thank you sir
You are welcome
Thank u so much sir 🙏... it helped me alot ..
Most welcome
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
Very good explanation 👍
I understand easily.
Glad it helped
Great sir may God bless you to give us more explation
Thank you, I will
All concepts are crystal clear....Thankyouu sir.....your way of teaching is wonderful....💟👍😇
Hello Sir... hope you're doing absolutely great. Thank you so much for such an amazing content.😇
This is one of your old students who is following you since Grade-9 and now I'm in Grade-11. Sir, I have honestly always loved your videos and your way of clarifying the concepts. I really request you to kindly start uploading videos for 11th Science. Would be of great help, Sir.
Please consider this request and start uploading as per time permits. 😊🙏
Hoping for a reply.
Please
Thankyou sir you are one of the best teacher in the field of physics
Great to hear that you liked the video :) Thanks a lot!!
Q1) ans= -9.8m/s^2
Because, when we thrown the ball upward there's retardation means decreasing The acceleration means negative acceleration so it is- 9.8m/s^2
Q)2 ans= (u)=0m/s
(v)=30m/s
(t)=1 min = 60 sec
a=v-u/t =30-0/60=
30/60=1/2=_0.5m/s^2_
Q3)ans= it is accelerated motion because, 🐝 bee is flying randomly but it changes it's direction and it's velocity is constant hence bee is in accelerated Motion........
👌👌👌👌👌Thanks sir for understanding me very clearly and nicely really sir you are great ,sir one boy or girl commented you that plz talk in Hindi but sir when you talk in English then we will understand it More clearly thanks sir.....🙏🙏🙏🙏
Brother ... velocity is change in speed and "direction" and we know that if velocity is same or constant then acceleration is 0 ......
but the given question direction is not same so velocity is not constant that is why 🐝 bee is in accelerated motion ....❤️
Your answer is correct but your explanation is kind wrong 😅🙏🏻👍
Thank u soo much sir. Great explanation👍👍
Most welcome
Sir bundles of tnks from a years we studying only theory thats why we not understanding clearly,practical work is one of the best work and now my concept become clear to watch this video ,sir you are the great person.May an evil eyes not affected ❤❤❤❤❤❤😊😊🤗🤗🤗
practical is the best process to learn👍👍
thank you sir
Q1] 0m/s^2
Q2] 0.5m/s^2
Q3] YES, it is accelerated motion because the bee is moving randomly that means u and v are not constant and[ the bee is applying force to move]* additional
Most welcome
First wrong
@@trisanjitsarkar624 Thank you for your comment I got the answer -9.8m/s² please tell if it is right 😀
@@kamalendubhattacharjee2219 yes it's right now
@@fahimcreatives8475 Thank you
Your teaching is really very unique and interesting thank you so much sir for clearing my concepts in your each and every video 🙂🙂🙂🙂🙂
Are you real bts
@@madhiraashok2582 SANA BTS means I'm a Army 🙂
Q.1
Ans:since the ball is thrown upwards it reduces it's speed also known as retardation and since no data is provided it's value will be 0m/s²that is option (c).....
Q.2
Ans:0.5m/s²
Q.3
Ans:no the bee is maintain a constant speed but the bee changes it's direction so it is accelerating...
That's just my understanding and pls correct me if I'm wrong ✌️✌️
And yeah thanks for the video need more videos related to this subject that is physics ♥️
Thank you 😊
did you know this aswer is right
Sir, Your explanation made the concept compelety clear to me. Thank you Sir.
You are most welcome
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.
Sir your teaching style is very unique....I highly appreciate your teaching style...❤️❤️❤️
Thanks for liking
1ans.(a) 9.8 m/ s^2
2ans.1/2m/s^2
3ans. Yes,it is acceleration motion because it is in random speed
Sir your teaching way is so much great.
I want just teachers like you.
Wow, thanks
@@ManochaAcademy I must say thanks sir. 😍
@Toki 🤠
this sir is very practical and he should continue this in future too i like this type of teaching
Q.1 (b)
Q.2 (1/2m/s)
Q.3(yes , because it changes its velocity with change in direction)
😍
Sir you are genius and you teaches better than my teacher
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.
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.
Ans of q1=-9.8m/sec square
Ans of q2=0.5m/sec square
Ans of q3=yes. Because acceleration happen when speed or direction of a body change.
2nd answer should be 2 right ? Because 60 can be divided by 30, because 30×2 = 60,,
Good practical example. Thank you sir
Great explainasion sir, i liked this video too much
Thanks for liking
