Since 2k22 I'm following this channel, my total knowledge was gained by the help of this channel i'm very grateful to you . I have changed alot coz of this channel very very big thanks.
i am confused with the puppy example. you raised the potential energy of the puppy which means you transferred energy to the puppy so how is there no work done blse the definition of work is clearly stated as the amount of energy transferred?
There is no kinetic energy in a moving mass there is force Mv squared, kinetic energy is the energy of consistent work from a consistent force regards Graham Flowers
I was wondering the same thing. If work is equal to kinetic energy. Then, did he skip a step when creating connection between kinetic energy and work. When kinetic energy is equal to 1/2 m x v^2. I am very confused...
Sir I was looking for exact explanation 😃 video now I have understood after my school n College Life 🤭 Thanks a lot sir u deserve a lot of thanks 🙏🙏🙏🙏🙏🙏🙏🙏
There's work done by you thus making you lose energy, which is then gained by the cupboard but just as quickly removed by friction as it does negative work (probably converted into heat and sound) so there is no kinetic energy left in the cupboard
The math equation explanation is correct. However, the push cupboard and raise puppy examples need to be broken into two parts: acceleration from rest, and deceleration back to rest. That would be a better explanation.
I think explaining the first situations as adding/removing kinetic energy is not appropriate since you can't just add or remove energy. there's actually conversion of energy working behind it.
Thanks, I think I should have worded that better! You can always add/remove energy from any object. It's just that that energy has to come from/go somewhere. In the case of the video, that energy is coming from/going to my body!
The work done by the gravitational force is the negative of the change in potential energy. Hence, the work done by an external agent (you) to move the puppy up against the gravitational field is mgh (the total gained potential energy). By moving the puppy up slowly (quasi-static, constant velocity, dynamic equilibrium, neglecting inertial effects) i.e. Fnet=F-mg=0 at all times If we are talking about the net work done, the net force (Fnet) on the puppy is always zero, and therefore the net work done (by the external agent + the gravitational force) on the puppy is zero

Words can't explain how much I am grateful to this video. GREAT JOB!!!!!
👍🏻
I agree strongly with you
Excellent explanation. I totally understood it. Earlier I was really confused about it. Thanks a lot!
I can't understand why this video only has 1 500 views on the time of this comment It's so well explained !
😒
Yaa
Yes
I swear to god it's always an Indian guy who does it better . Excellent explanation

12th grader here! You're such a blessing Mr. Mahesh, this video helped me a lot to clear my doubts
It really healped me .... thankyou sir😀

i too have the same doubt if you got the ans reply
I have never seen a teacher like you

why dont they teach so good in schools
???

I love you Sir, Best thing this video helped me get 4 marks in my exam 🤩🤩
Such a clear explanation. Thank you bhai
The mathematical explanation for work related to kinetic energy was so easy to understand. Thank you!
Phenomenal!!!!!!!!!!
Sir I was looking for exact explanation 😃 video now I have understood after my school n College Life 🤭
Thanks a lot sir u deserve a lot of thanks 🙏🙏🙏🙏🙏🙏🙏🙏
You cleared my confusion Sir Mahesh, Thankyou!
Wow! So simply explained!
A really wonderful explanation thank you sir
😊Thanks sir,you made this theorem as smooth as butter for me 😊
This video is helpful for me 😊
Thanx you for making this video
how does this only have 200 likes? its an amazing explanation
Loved it mahesh sir you are so awesome physics guru
Im confused about the cupboard. work = force x displacement. In the example, a force was applied and there was displacement so how is there no work?
There's work done by you thus making you lose energy, which is then gained by the cupboard but just as quickly removed by friction as it does negative work (probably converted into heat and sound) so there is no kinetic energy left in the cupboard
Because friction acts in opp direction , so total work done is zero
That was so helpful thankss!!
Wonderful explanation sir😊😊😊😊😊😊😊😊😊😊😊.
Learn alot from this video thank you keep it up❤
The proof why you solved for every equation makes sense than the thing done in my TBK. I am so happy that I got an explanation something like this
thaaaaanks well explained be blessed
your explanations are great, please make more videos :) Love from England
What about the gravitational potential energy of the puppy being raised? 8:00
Sir thank u soooooooo much i can't explain how helpful is this video ❤❤❤❤❤❤
Very clear and to the point! Much appreciated! By the way, as a side note, gravity can't push, only pull.
That's relative
Superb
Very underrated......
Thank you so much well explained
This man is so good 😊
The math equation explanation is correct. However, the push cupboard and raise puppy examples need to be broken into two parts: acceleration from rest, and deceleration back to rest. That would be a better explanation.
Tank you.
thank you soooooo much!!! i have an exam three days from now and this has helped me immensely :)
I hve one tommorow 😢😢
I think this video needs more views and likes🥀
SO GOOD THANK YOUUUUUUUUU

For the case of the puppy, isn’t ur work done the gain in gravitational potential energy, mgh? How can it be 0?
The work done by the gravitational force is the negative of the change in potential energy. Hence, the work done by an external agent (you) to move the puppy up against the gravitational field is mgh (the total gained potential energy).
By moving the puppy up slowly (quasi-static, constant velocity, dynamic equilibrium, neglecting inertial effects) i.e. Fnet=F-mg=0 at all times
If we are talking about the net work done, the net force (Fnet) on the puppy is always zero, and therefore the net work done (by the external agent + the gravitational force) on the puppy is zero
What about the work energy theorem in a resistive medium ???
Thank you!!!!
Great sir
He sounds exactly like the guy from Floathead physics
KYNETIC energee
I can recall Mahesh voice
nice video
In the mathematical equation where did the 2 go
??
It will be mv^2/2-mu^2/2
Which will be further 1/2×mv^2 - 1/2×mu^2
Now, W=K.E final -K.E initial
Good explanation but there are some misconceptions too!!!
how do i get songs out of my head
Seriously😂😂😭like howwww
