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
I like teachers teaching and showing practical examples

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.

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!
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
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
Ans1; -9.8m/s²
Ans2; 0.5m/s²
Ans3; It is in accelerated motion with changing velocity in every direction.
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
Sir waste 100 rs of petrol to tell us concept 😄😄🤣
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)
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

Your all question is right bro
ANSWERS TO TOP THREE QUESTIONS
1)_ 9.8m/s(square)
2)1/2 m/s (square)
3) yes, it is accelerated motion.because the rate of change in velocity is called acceleration in the above situation bee flying randomly it means there is a change in direction so automatically there will be change in velocity also so it is in accelerated motion. Thank you
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.
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🤔
Who watching this vidow in 2024😂😅
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
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.
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.

Yes u are right
1) B
2) 0.5 m/s2
3) yes...because direction will change
1 ka c
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.
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 ..!

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
1) 9.8m/sqaure
2) 0.5m/sqaure
3) because the direction is changing
1,If I'll throw a ball in upward direction then due to Earth 's gravity it's velocity will decrease and as velocity decreases there will be retardation (-ve acceleration ) So acceleration= - 9.8m/s^2। 2.0.5m/s^2. 3.Given, Speed= 1m/s = constant. Direction =random ( not constant ) Velocity means speed with directions, here speed is constant but direction is random So bee is in 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..... 🙂🙂🙂
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😊

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 .
The answers are:
1)- Here,
Initial velocity (u) is greater than 0, and the final velocity (v)=0. Clearly, it is a case of retardation.
Hence, acceleration is -9.8 m/s^2.
2)- Given, u = 0 m/s
v = 30 m/s
t = 1 minute
= 60 sec.
We know, a = (v - u)/t
→a = (30 - 0)/60
→a = 30/60 = 0.5 m/s^2.
Hence, acceleration of the car is 0.5 m/s^2.
3)- Since the direction of the bee is continuously changing, therefore it is in accelerated motion.
