I agree strongly with you

I can't understand why this video only has 1 500 views on the time of this comment It's so well explained !

Yes

Excellent explanation. I totally understood it. Earlier I was really confused about it. Thanks a lot!

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

The mathematical explanation for work related to kinetic energy was so easy to understand. Thank you!

Such a clear explanation. Thank you bhai

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.

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 🙏🙏🙏🙏🙏🙏🙏🙏

It really healped me .... thankyou sir😀

why dont they teach so good in schools ??? ???

😊Thanks sir,you made this theorem as smooth as butter for me 😊

A really wonderful explanation thank you sir

your explanations are great, please make more videos :) Love from England

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

how does this only have 200 likes? its an amazing explanation

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

thank you soooooo much!!! i have an exam three days from now and this has helped me immensely :)

Phenomenal!!!!!!!!!!

You cleared my confusion Sir Mahesh, Thankyou!

Loved it mahesh sir you are so awesome physics guru

I swear to god it's always an Indian guy who does it better . Excellent explanation

I love you Sir, Best thing this video helped me get 4 marks in my exam 🤩🤩

Learn alot from this video thank you keep it up❤

Very clear and to the point! Much appreciated! By the way, as a side note, gravity can't push, only pull.

That's relative

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.

That was so helpful thankss!!

thaaaaanks well explained be blessed

Thank you so much well explained

Very underrated......

Sir thank u soooooooo much i can't explain how helpful is this video ❤❤❤❤❤❤

Superb

SO GOOD THANK YOUUUUUUUUU

Wonderful explanation sir😊😊😊😊😊😊😊😊😊😊😊.

This man is so good 😊

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!

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...

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?

Thank you!!!!

I think this video needs more views and likes🥀

Good explanation but there are some misconceptions too!!!

For the case of the puppy, isn’t ur work done the gain in gravitational potential energy, mgh? How can it be 0?

@drofeng

Жыл бұрын

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

Great sir

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
