Arey, 6th qn is wrong. you hv used wrong formula yaar. Actually speaking, 2as = v^2 - u^2. But, you have taken 2as = u^2 - v^2. KINDLY CORRECT THIS MISTAKE!
You are wrong...eqn to be used here is (v1+v2)/2....the eqn u mentioned is used when "half of the distance" is covered with speed v1 and the other half with v2
@@san4301 if you even check it in half t, Distance 1 =s×t I.e, 40×t/2, 20t=Distance 1 similarly Distance 2= 30t avg. speed= total distance/total time =(20t+30t)/t hence avg speed=50km/h
Your class on this chapter is so good like how they teach in school with clear concept and method
Thank you sir
Thanks and welcome

No he is correct it is retardation
Dude it's correct only he took it in sense of retardation
No he did it correctly
Please solve more questions please. you are doing wonderfull teaching
Yes really
we can use the formula v1+v2/2 then 6+8/2 = 14/2 = 7 at 2:12
I was just about to ask the same
Sir excellent 👍..you and chemistry mam classes rocking
Keep watching
Sir, could u plz do the same for other physics chapters also...plz...
Like AC, Electromagnetic waves, and Electromagnetic induction...plz sir....
Sir for 5 th question we can take 2vlv2/v1+v2
Yes because the object travels equal distance
thank you so much for this most helpful session sir..😊..helped me a lot sir..
Keep watching
way of teaching is excellent
Keep watching
For 4th question better to use v1 +v2 by 2
Thankyou for this wonderful class sir.It's very interesting.
You are most welcome
Thankyou sir for this wonderfull video and very nice explanattion sir
17:04 "if we subtract- "
My sleepy head: why!? Why should i subtract what's the logic behind it. I need a derivation for it 😵
For 1st question better to use 2(v1)(v2)by v1+v2 for easy calculation
But it's wring
Tq for your wonderful class sir
Thank you ❤️
You’re welcome 😊
Sir may I know why in 10th question both velocities are subtracted and in the previous 9th question velocity added....???
Nice explanation sir.
Thanks sir... It helped a lot.
Most welcome!
Is it enough for neet
Hi sir
I have doubt that 1st question answer his 6.85 how did you choose option bis correct answer plz answer me
Because 6.85 is close to 7
I like you sir I love u❤️❤️❤️❤️
Nice sir please give me link for physics motion in a straight line video your explanation very nice
Sir 6th question how to convert 36kmh-1 into metersecond
Sir you are telling so direct method not giving full explanation, what we begeners do?
this is practice for neet not for beginners
Sir how to note total time 2t
Sir 7th one not understanding sir
Physics ln-3 important 2 marks, 5marks , sums podunga plz
Thank you sir ❤️❤️
All the best
Are u making us to rote learn sir. Give the explanation completely.
Sir why in 2 q time is taken as 1
How did you get 3+1, on 5th question
😒
By taking LCM of 40 and 120 as 120
Thankyou ❤️
You’re welcome 😊
Excellent teaching sir
Thanks and welcome
Thank you so much sir ❤️
All the best
VAverage=v1+V2/2
Thank u so much sir...
All the best
Thank you soo much sir! ❤️
Keep watching
Super sir
21:30
Sir motion in a straight line ki nomerical questions
Thank you sir
Welcome
4th one is wrong sir..
Its answer is 48...
(2×v1 ×v2 )/v1 +v2
I got the same ans 48

@@san4301 if you even check it in half t,
Distance 1 =s×t
I.e, 40×t/2,
20t=Distance 1
similarly Distance 2= 30t
avg. speed= total distance/total time
=(20t+30t)/t
hence avg speed=50km/h
Go with the method dont rely on the shortcut formulas.the question solved here is absolutely correct
Your very smart boy
Tq sir
Pls practice more questions sir
Sir your Q4 is wrong answer is 48km/h
Sir say time save mothed
👌🏻
Sir 4 and is wrong
Please teaching in kannada explaination
😂😂😂no he cant
PLZ SPEAK WITH HINDI ENGLISH BOTH LANGUAGE
Noo
Sir u r doing wrong!
Nuub teacher
Thanks you sir
Welcome
Thank you sir
