Very nice videos bro all the best to complete 100k subscribers. We all will support you.❤😂😅

Thank u bro I saw ur video once and I wrote it in just 5 min non stop keep going continue making this type of videos💯💯💗

[@nirmal6030]

Workdone k formula hota h change in kinetic energy or velocities km/h m h to SI unit m lane k lie 5/18 se krte h ya aplog pura 5X1000/3600 krskte h thn after changing in m/s put in formula of K.E yani 1/2mu2 or then 1/2 mv2 or fir dono k K.E ko minus krdngy thats it !🙂
or ncert book m har jgh alg h kisi ka alg or kisi k alg...

[@amarjeet-mc3mm]

Sir but answer is 156250J in NCERT your answer is different 156375J

[@bhavya_manasaaaaa]

Ya because he converted the division into decimal

[@redaim8031]

In my book its 156250

[@Yashu495]

Bro it's approx value so it is right

[@pinkalpatel8599]

Bro please don't convert value in decimal bec it is very long method try to put value in fraction p/q form👍👍

[@pinkalpatel8599]

Your answer is same 156250j

[@farheenfatma49]

Your voice just like ankit sir 👍😘

[@rudrachannel3255]

Sir in my NCERT book answer is 156250 J

[@PRINCE-uc2dh]

Well done 😎

[@silentnature8448]

My thinking Sir your answer is wrong because my ncert book answer is 156250 Joule.
Please sir check your answer again carefully many childrens are mistaken Sir.

[@editepic9245]

Thanks you so much

[@studytip9820]

Sir I have questions why we change
Km per hour in metre per second

[@cyber_tech_pro]

SI unit bro! CGS (Cm,gram,second) and MKS (metre,kilogram,second)
Here the mass is in kg so in mks kg is with metre and second so m/s

[@danishmushtaqdraboo5729]

Nice. . .

[@danishmushtaqdraboo5729]

Super duper

[@yogeshnotfound]

but the actual answer in the book was 156250 J.

[@yogeshnotfound]

[@yogeshnotfound]

Mass of the car, m =1500 kg,
initial velocity of car, u = 30 km h-1
=
30 × 1000m
60 × 60s
= 25/3 m s-1.
Similarly, the final velocity of the car,
v = 60 km h-1
= 50/3 m s-1.
Therefore, the initial kinetic energy of
the car,
Eki
1
2
2 = m u
=
1
2
× 1500 kg × (25/3 m s-1)2
= 156250/3 J.
The final kinetic energy of the car,
Ekf
=
1
2
× 1500 kg × (50/3 m s-1)2
= 625000/3 J.
Thus, the work done = Change in
kinetic energy
= Ekf - Eki
= 156250 J.

Sir thumbnail book NCERT ka LGA diya kro aaassni hoti hai

[@laaatagaming3503]

Why we convert km/h to meters per second??

[@aru8692]

Bcz velocity is measured in m/s

[@laaatagaming3503]

@@aru8692 thanks dude

[@Yguy]

@@aru8692 Velocity can also be in km/h but we need the answer in joules, (which is N m) so we need to convert.

[@aru8692]

@@Yguy oh okay thank you!

[@Nitishkumar-gc8ku]

soo cool

[@evlinevlin479]

We can also do it by
W = F×S
= m×g×v² - u²

[@gazalkaushik]

Sir is ko m/s m kyu convert krna h

[@shrietex3562]

Because velocity SI unit is m/s so that's why he converted

Bhai your study is good but it is 8.33 not 18.33 .

[@plaksha13]

no youre wrong it will not be 1 because 2 is smaller than 3

[@minety_pie]

U converte kmph to mps
By multipleing 5/18

[@SUMIT-jx8ck]

Good 👌👌👌👌

[@Pratik_P4]

bro bu in my book he answer is different

[@naimuddinansari9097]

Sir k.E

[@adityachaudhari6478]

But answer is different

[@akanksha9996]

Thank u sir😊 really it is helpful for us 👍👍

[@MR.SHIVA.RAJPUT_062]

Sir workdone pucha hai to kinetic energy kyu nikalna hai
W=f multiply s

[@aru8692]

Bcz energy = work and work = energy so you can use kinetic and potential's formula to find work done

[@akshraa2007]

Work= energy

[@Yashu495]

Workdone =kinetic energy

Why we had change to m

[@dipakadhikari9021]

Thank you

[@12bsapna57]

Thank you sir

[@ravneetkaur688]

Why you convert initial and final velocity into m per second??

[@shrietex3562]

Because velocity SI unit is m/s so that's why he converted
