All NCERT Questions from Work and Energy | CBSE Class 9 Science Physics Chapter-11 | CBSE 2024

[@mdsanu97]

For questions 21 :- if objects free fall to ground the U is converted into K . K= max If object hit hard to the ground then energy convert into sound and heat energy That's all thankyou ❤❤❤

Sir, you have missed v² in question no 17

[@okokopop3993]

Yes U are saying correct

[@gwpratyush8256]

Bro because it is zero as the car stopped

[@PronabMandal-yq3ej]

Q 17 wrong Sir 60 ka sq. Kiye hi nahi 😢

[@flykidgamer3568]

​@@PronabMandal-yq3ej no because 60 is in km/h but distance sI unit is in meter

[@flykidgamer3568]

​@@gwpratyush8256 he means u square

Great Explanation Sir 👏 Thank You Sir

[@pagg22]

Real vedio starts at 1:45 thanks me later 😢❤

[@AyushKumarSah-g9v]

Answer of question 21 : If the object is free falling to the ground, its potential energy gets converted into kinetic energy with decrease in height. Furthermore, on reaching the ground, all the kinetic energy gets converted into heat and sound energy. Thanks you!! Please like my comment😃👍

[@kidarnathgupta2467]

Thanks bro

[@shravannaik8798]

For the question 21 : The kinetic energy of the body will get converted into potential energy

[@blu4278]

When an object falls freely towards the ground, its potential energy decreases and kinetic energy increases. As the object touches the ground, all its potential energy gets converted into kinetic energy. As the object hits the hard ground, all its kinetic energy gets converted into heat energy and sound energy.

[@MaganSingh-jo1xm]

Not wright

[@samyuktha.a7579]

Sir please start gravity chapter………please

[@Vedantukevedanpro]

Sir kindly start gravitation chapter because our mid terms are finished and my physics ma'am has started gravitation chapter ,,,plzz sirrr🙏🙏🙏🙏🙏

[@Arch-ki5dr]

All of its kinetic energy gets converted into potential energy

Question 17 me 50/3 ka square hoga but session was awesome 🔥

[@JasdeepSingh-nb4bt]

Wow super nice kya padate he😂

[@misdesk9148]

Really nice explanation sir

[@GudduRoy112]

Sir but third equation of motion is (v²=u²+2as) so how can it be (v²=2gh) please explain sir i didn't understand question no. 10🙏🏻

[@zaidahmed6299]

a converted into g and s converted into h

[@yashpundir8079]

G is acceleration due to gravity and distance (s) is height so it can be replaced

[@sivanikumari1267]

K.E Chang into Sound energy

9:17 sir light energy bhi hai

[@mohankumarvenkatesan8360]

Q 21 The Kinetic energy increases and becomes maximum

[@rajadeepa4390]

Super sir bahut acha sir ❤ thankyou for your support ❤

[@NayanKumar-m1d]

Que 17 is wrong

[@Nikkugangwar806]

Ya, because he didn't square the 50/3

[@kirishrameshkumar8063]

Sir a small doubt sir in 19th question don't we not have to square 50/3 sir.

[@nazeemasadik2630]

Everyone will top this exam🤎

[@Quattowastaken]

Sir, Question 10 is wrong. The object doesn't stop halfway down. It can't have u=0.

[@rashiagrawal2425]

It is right as if the object will have been stopped, the final velocity will be zero. The u is taken from when the object is dropped by the height of 5 metres.

[@ThakurSaurabhSinghoffici-nz1bk]

[@razzak._.khxn.]

Q17 is wrong sir doesn't square (50/3)
