Thank you sir....Explian the difference among...Uniform speed ,uniform motion and uniform velocity... Non uniform speed,non uniform motion and non uniform velocity..
Q1 and Q2 are correct :) Answer of Q3 is 24 km/hr. Here is solution: Let's start with the formula for average speed = total distance / total time But since the distance is not given in the sum, we can take total distance as 2x. So 1st half distance is 'x' and 2nd half also is 'x'. Now to calculate total time … Total time = time of 1st half + time of 2nd half time = distance / speed So we get total time = x/20 + x/30. Now plug in the values in the main formula Average speed = 2x / (x/20 + x/30) = 2x/ (5x/60) = 24 km/hr
1.instantenous speed 2.as velocity is speed with direction, although it has a uniform speed but as it turns so it's direction is changing so velocity is not uniform 3.total distance=20km+30km=50km Total time=1h+1h=2h Avg.speed=total distance ÷total time So, =50/2km/h=25km/h
50 is not the total distance, it's the total instantaneous speed, so it can't be putted in the place of distance in the formula, average speed is distance/time
@@abhiram.p.udayakumar6617 Its all dependent on you... But most of the questions want km/hour to be converted to m/s...so make it as a habit while solving the questions related to motion....
Really I'm fell in love with your teaching skills so the ans are Q. Speedometer measures the speed of a vehicle. Q2. No, when we turning the speed become slows down. 13. Idk
Q1) Speedometer measures the Instantaneous Speed. Q2) No the car does not posses uniform velocity as it has changed its path from straight line. Q3) 20+30/2 = 50/2 = 25 km/h
Your answers of Q1 and Q2 are correct :) Answer of Q3 is 24 km/hr. Here is solution: Let's start with the formula for average speed = total distance / total time But since the distance is not given in the sum, we can take total distance as 2x. So 1st half distance is 'x' and 2nd half also is 'x'. Now to calculate total time … Total time = time of 1st half + time of 2nd half time = distance / speed So we get total time = x/20 + x/30. Now plug in the values in the main formula Average speed = 2x / (x/20 + x/30) = 2x/ (5x/60) = 24 km/hr
1)The speedometer measures the instantaneous speed of the car. 2)The velocity of car will change if it takes turn as direction will change. 3) Let the distance be x km . So, time for first half distance= distance/speed ( X/2 )/20 hr=x /40 hr Time for second half distance = distance /speed=(x/2 )/30 hr =x /60hr Total time =x /40 hr + x/60 hr=5x/120 =x/24 hr Total distance =x km So average speed = total distance/total time = x/(x/24)km/hr =24 km/hr

Very very appericiation all video upload by manocha academy I like each video , i watched all video . Very very knowledgeful video by manocha academy Thanks manocha academy :)
question 1 ans is: The speedometer of a vehicle measures the instantaneous speed of the vehicle, which is the rate at which the vehicle is traveling at a specific moment in time. This is typically displayed in units of kilometers per hour (km/h) or miles per hour (mph), depending on the region. question 2 ans is: No, the car does not have uniform velocity. While the car may be moving at a constant speed, velocity is a vector quantity that depends on both speed and direction. Since the car is turning, its direction is changing, and therefore, its velocity is not uniform. qusetion no 3 ans is: Average Speed= Total Time Total Distance Let's assume the total distance is 𝐷 D. The car covers half the distance ( 𝐷 / 2 D/2) at 20 km/hr and the other half ( 𝐷 / 2 D/2) at 30 km/hr. Step 1: Time taken for the first half The time taken to cover the first half of the distance ( 𝐷 / 2 D/2) at 20 km/hr is: 𝑡 1 = 𝐷 / 2 20 = 𝐷 40 t 1 = 20 D/2 = 40 D Step 2: Time taken for the second half The time taken to cover the second half of the distance ( 𝐷 / 2 D/2) at 30 km/hr is: 𝑡 2 = 𝐷 / 2 30 = 𝐷 60 t 2 = 30 D/2 = 60 D Step 3: Total time taken The total time taken is: 𝑡 total = 𝑡 1 + 𝑡 2 = 𝐷 40 + 𝐷 60 t total =t 1 +t 2 = 40 D + 60 D To add these fractions, find the least common denominator: 𝑡 total = 3 𝐷 120 + 2 𝐷 120 = 5 𝐷 120 = 𝐷 24 t total = 120 3D + 120 2D = 120 5D = 24 D Step 4: Average speed Now, we can find the average speed: Average Speed = 𝐷 𝑡 total = 𝐷 𝐷 / 24 = 24
km/hr Average Speed= t total D = D/24 D =24km/hr So, the average speed of the car is 24 km/hr. SIR IS THIS CORRECT ANSWER Here it is: "If I write that you don't give any answers in the comment box."
1. Instantaneous speed 2. No.when car makes a turn it's direction changes so velocity changes and it is a non uniform velocity. 3.direct formula Average speed=2×v1×v2÷v1+V2 You will get the answer as 24 km/hr Please correct me if iam wrong somewhere.
@@yellapudevisravani6603 see sister whenever a body changes direction of motion its velocity changes even though it is travelling with uniform speed therefore a car taking a turn at uniform speed does not have uniform velocity ok🙂
@@yellapudevisravani6603 i said instantaneous speed because speedometer deflects whenever there is change in speed or acceleration so it gives speed at that instant of time alright👍
1- A speedometer measures the speed of the vehicle 2- No as the car has a turning point and it's direction changed 3- 20km/h =10km/h(half) 30km/h=15 ,average speed =10+15=25

TOP 3 QUESTIONS BY AVIGHNA DARUKA 1)The speedometer measures km/hour or instantaneous speed. 2)No, the car doesn't has uniform velocity since the direction has changed. 3) Easy, you find the average speed by applying the simple formula of a sum divided by count. Thus, 25+35= 50 divided by count = 25 THANK YOU FOR READING *****************end of comment please like*****************
3rd question . car speed for half distance = 20 km /h other half distance = 30 km/h = 20 km/h + 30 km/h =50 kg/h avg speed = total distance /total time avg speed = 50kg /h 0 because the time is not given (measure) so answer is 50 kg /h
You can find the time as (Total distance 's'=2x) t1=s/v =x/20h And,t2=x/30h So, total time taken=x/20+x/30 =x/12 Average speed=total distance/total time taken =2x÷x/12 =24km/h
1. The speedometer of a vehicle measures the instantaneous speed. 2. No, because the uniform motion is when the speed is constant and direction is the same. As shown in the video, the car take turn which does not meet the criteria to be included in a uniform motion; therefore, it is a Non Uniform motion. 3. The average speed of the car is 24km/h

= 50/2 = 25 km/h
∴ The average speed of the car is 25 km/h

1) Instantaneous Speed
2) No because the direction has been changed.
3) 30 + 20 / 2

Am I right?
Q1 and Q2 are correct :)
Answer of Q3 is 24 km/hr. Here is solution:
Let's start with the formula for average speed = total distance / total time
But since the distance is not given in the sum, we can take total distance as 2x.
So 1st half distance is 'x' and 2nd half also is 'x'.
Now to calculate total time …
Total time = time of 1st half + time of 2nd half
time = distance / speed
So we get total time = x/20 + x/30.
Now plug in the values in the main formula
Average speed = 2x / (x/20 + x/30)
= 2x/ (5x/60)
= 24 km/hr

your channel is the only one which helped me up til now thanks
Most welcome
1)The speedometer measures the instantaneous speed of the car.
2)The velocity of car will change if it takes turn as direction will change.
3) Let the distance be x km .
So, time for first half distance= distance/speed
( X/2 )/20 hr=x /40 hr
Time for second half distance = distance /speed=(x/2 )/30 hr =x /60hr
Total time =x /40 hr + x/60 hr=5x/120 =x/24 hr
Total distance =x km
So average speed = total distance/total time = x/(x/24)km/hr =24 km/hr

but 3rd will be 24 km/hr
Sir your explanation is good
3rd question .
car speed for half distance = 20 km /h
other half distance = 30 km/h
= 20 km/h + 30 km/h
=50 kg/h
avg speed = total distance /total time
avg speed = 50kg /h
0
because the time is not given (measure)
so answer is 50 kg /h
It's km/h
24km/hr
You can find the time as
(Total distance 's'=2x)
t1=s/v
=x/20h
And,t2=x/30h
So, total time taken=x/20+x/30
=x/12
Average speed=total distance/total time taken
=2x÷x/12
=24km/h
