K.E=1/2 mv 2 K.E=1/2m (2v)2 K.E=1/2m × 4 × v2 K.E=1/2 mv 2 × 4 K.E=1/2 (1/4) mv2 Here 1/2 and 1/4 are cut and it become 1/2 So it becomes K.E=1/2 mv2 K.E=K.E
Yes ma'am in the second question there will be no change in the kinectic energy of an object when the mass get decrease d and velocity gets doubled Ma'am I didi this question in my copy
1.if v=2v and mass is decreased to 4 times. Then there will be no change in K.E 2.if h=2h then P.E will be twice. Note: If we are talking general then the mass will remain constant of the same body.
In the last question there will be no change in kinetic energy Btw ma'am your explanation is full of clarifications, it cleared my all doubts regarding energy 🙏 Thand you so much for this lecture 😊
mam aik question hai kay insan kay andher say jab rooh nikal jati hai to kam krna chor deta hai to kya jo rooh hai wo energy hai jo insani jism ko kam karnay par majboor karti hai?????
In the first que the KE = No change And in the 2nd questin PE= increased by 2times of PE. Great & Lots of thanks ma'am for this video, your explanation is cristal clear & practical...... Please keep it cotineous🙏
Seriously i have seen many video but i can't found any video like this ,this video help me a lot
K.E=1/2 mv 2
K.E=1/2m (2v)2
K.E=1/2m × 4 × v2
K.E=1/2 mv 2 × 4
K.E=1/2 (1/4) mv2
Here 1/2 and 1/4 are cut and it become 1/2
So it becomes K.E=1/2 mv2
K.E=K.E
K.E is also decrease by 1/4m times

Thank you so much for this education ❣️Allah aap ko hamesha khush rakhe❣️
Ameen
Jai shree Ram 🚩
Your lecture was useful regarding practical applications of energy .
Good.
jbrdast💖💖
K.E. remains same & P.E 2 times .
Thanks for clearing all doubts 👏
Yes 👍🏻
Ok
Thank uh mam for guiding and thank to clear my dout☺☺ bhgwan apko kush rke 🤗

Hi
Qasam its amazing dear big love and much respect❤❤
Thanks because of you i understand now how to derive kinetic energy.
A figure among cypher.
Good 😇😇
Your explaination is so good 👍
Mashaallah. Great explanation. Excellent quality work.
Thank you Sir......

Thand you so much for this lecture 😊
My pleasure
Wow great explanation ❤️🥰 mam you are great in the world physics 🥰last vala ka ans no any changes remain same of kinetic energy
Ans sahi h mam
Perfect explanation ❤
Thanks diii😇🤗...u explained with ease🥰
Wow great job superb 👌
Lajwab bhut khoob
Wow fantastic explanations... ❤️😁
This lecture is so informative finally I clear my confusion. I did last qustn thnku mam keep it up
My pleasure 🙂
Excellent God bless you
Great explaination 🙏
Weldone❤️ excellent lecture
Excellent ma'am I was searching for this type of video🙏❤️☺️
Same here💜😄
Outstanding teaching mam
Thanks for great 👍🏻 explanation 🙏🏻🙏🏻
Explanation is very good and I can understand ur explanation ☺️
Glad to hear that
Allahamdulilah ❤️
In second question there is no changes in kinetic energy if velocity is 2 times and mass = 1/4 mass
K.E= KE( equal)
P.E=2 times
🤚🤚
Awesome explanation 😊
Really madam good explanation 🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻
GooooooooooooooooooooooooooooooooooD miss❤❤❤
Very nice thanks dear
Thank you so much for this video
Bhut ache mam mam aap law of motion ki complete video bna kar bajna
Very beautiful work mama
Very nice video great 👌 explanation
Simple explanation
Great work mam keep it up
V. Informative videos !!!
Thank you, I will
@@FalakSoomro ok Thanks
May Allah help u sis!
Really ur way of presentation is very nice
Thanks a lot mam . You are the best ever teacher to me
Shukriya mam
Nice explanation.
Nice explanation mam
Thankyou ma'am for this video !!
My pleasure 😊
Too good
11:22 same /equal to K.E*1
Bahutt mst padhata h aap
Excellent mam 👏👏
First question ka answer k .E =1÷2×(2v)2×1÷4m=1÷2×1÷4(v)2×1÷2=1÷2m(v)2 therefore kinetic energy=kinetic energy. Maim,my answer is right ya wrong.
right
1.If v=2v and mass is decreased 1/4 times then kinetic energy will become 3 times K.E
2.if h=2h then P.E = 2mgh.
Am i right maam???
Yes P.E will be 2mgh ................but K.E should be the same. plz recheck your answer
Apki age??😛
nice bahen ji ,,create this kinds of video
Thanks because of you I understand
Best explanation
2:35
Quantum
Mam mujhe really doubt tha potential energy and kinetic energy ke bich Jo ab clear ho gaya hai thanks mam for this information
Glad to hear that
Nice
Aapke video se laga juggling seek jaenge lekin potential aur kinetic energy samajh a gai 😆😁🤗
Thank u so much mam
Mam op level explanation and the ans. is k.e=k.e and p.e =2
Good Teaching Madam...🙏
mam aik question hai kay insan kay andher say jab rooh nikal jati hai to kam krna chor deta hai to kya jo rooh hai wo energy hai jo insani jism ko kam karnay par majboor karti hai?????
You are good teacher 😃😃
Love you mam super explain
Aap ki aawaje bhi masa Allah bahut khub ha
Masha Allah I am totally appreciate to you
Go ahead sis 🎉
Thank you so much 😊
Thank you ma'am 🙏🙏❤
Thank you mam
Starting word is very powerful word in the 🌎 world
Wao well explanation thankyou so much mam
Nice lecture
In the first que the KE = No change
And in the 2nd questin PE= increased by 2times of PE.
Great & Lots of thanks ma'am for this video, your explanation is cristal clear & practical...... Please keep it cotineous🙏
Yes, correct
Yes Mam
Thanku ma am it is very helpful fot me in mu study thanku thanku very much
Yes
@@manishmishra4406 My pleasure
Very good mam
Awesome 👏
kya padati ho maam aap wahh
Good teacher
Eska ans mere toh K.E=4K.E nikala hia ... Ap bata skate hai ke ap bata sakte hai correct hai yah nhi
... Plz tell me ... 🙏👍👍🙏🙏
Answer is K.E = K.E kinetic energy will remain the same.
v=2v
m=1/4m
K.E = 1/2 * m * v^2
input values
K.E = 1/2 * 1/4 m* (2v)^2
K.E = 1/2 * 1/4 m * 4 v^2
K.E = 1/2 * m * v^2
K.E = K.E
Aye mashallah
Nice👏
Some doubts are clear from this video but some are not clear
Thanks alot....
Man the derivation is of constant forse
Kindly also explain the derivation of variable force by integration
jai shree ram 🚩🚩 bauth accha samaj me aaya
Thanks
Very good mam ....
Thank you
Kya madam
Humara force his direction me hai displacement bhi to usi direction me ho raha hai
To apne f=-m/g kaise le liye
ڀلوڙ
Very well explained ❤️❤️❤️mam
Nice voice....😊😊😊
❤ good ❤
Hi
Ability ha aap me smjhane ka
