Answer:
1. (a) Elastic
(b) Potential
(c) Gravitational
(d) Kinetic
2.( 500/1000)kg*1m*9.8
=4.9J
3. Both have same potential energy, because it does not depends on path.
Thank u sir.🤘😎
Only this person in whole RUclips ( according to me ) is doing very hard for only one and one purpose to teach the students who are not understanding topics not for earning money.
Great salute to this man
Happy to help
@@ManochaAcademy Thanks Sir for your reply
Sir, I'm stuck in one problem
Can you help me sir ?

ANSWERS:
1. Potential Energy and Kinetic energy
2. PE=M×G×H
PE=0.5 Kg(500g) × 10m/s²(Gravitational force on Earth is 10m/s²) × 1m
PE=0.5 × 10 × 1
PE=5 J
3. Both the boys will have the same potential energy as both of them have the same mass. The path taken to reach the first floor does not matter. So, the height also remains the same. Both of them are on Earth. So, the gravity is the same.
Thankyou!
Excellent!! All your answers are correct!!

@@ManochaAcademy cool teacher even I got the same
No teacher teaches in your way sir especially with live experiment. Hats off to you sir
The only topic I understood yet in full chapter. But I swear, a feeling if satisfaction when I opened book after seeing this video🤯🤯🤯. Thank you for the clarity sir.🤐👌👌👌👌👌👌👌
Q1 .a-elastic energy
b-kinetic energy
c-gravitation due to accelerate
d-kinetic energy
Q2-given
M-500g--500÷1000----0.5kg
H-1m
g-10
Soln.
P.E=mgh
= 0.5×1×10
=5j
Q3
Both boys Aand B Have same P.E has they both reaches same hight
No the gravitional constant 9.8+0.5
Hear 9.5 is constant
And 500g is mass of the the book converted into 0.5kg
Therefore 5.25 is answer

Thank u sir. Ur one of the best. It really feels better than school.
Most welcome
☺️
@@ManochaAcademy have u Sir any whatsapp group related to science
School is the best
I feel you
I'm italian and in these days I had searched a lot of video about these arguments and with this video i have finally understood everything, thank you so much
You are most welcome
Are you really an Italian?😀
@@ManochaAcademy Sir.. please make a video to the answer of q.no.1 that you have asked in the video.
Q 1. (a) Potential as there is a change in configuration. (b) Potential energy as it is on a height from the plane.
(c) It is also potential energy as thr ball is still on a height from the plane.
(d) It is kinetic energy as now the ball is landed on the surface and it gains kinetic..
BTW You are the one which master our concepts thanks a lot... You teach very good thanks for your help and work sir..
HOMEWORK:
Answer 1: (a) Potential energy as there is a change in configuration.
(b) Potential energy as the ball is on a height.
(c) Kinetic energy as it is falling
(d) Potential energy as again it was on a height from the reference (i.e. the table)
Answer 2 :(500g)(0.001kg)(10m/s^2)(1m)= 5 J
Answer 3 :Both of them will get the same potential energy on reaching the top
As potential energy depends on height to which a object reach not the way in
which it come , if it comes to the same height as of th other one the potential
energy will be equal of both of them.....
BTW sir you are a very great teacher and an angel for me thanks a lot for this video
I have understood all the concepts...Thanks a lot and please bring super amazing videos
like this ....

Question, in the formula PE = mxgxh where do you find the value for g, or is it usually 10m/s^2?
First time pata chala pure RUclips per koi physical examples lekar samaghya eatane acche se ❤❤❤
1)At A and D it has elastic potential energy, at B and C it has kinectic energy due to motion.
2)5 J (in SI unit)
3) both have same potential energy as potential energy depends only on height reached and not on the path taken.😊
1ans)A) potential energy stored it it .
B)potential energy converted into elastic potential energy due to change in it's configuration.
c) elastic potential energy converted into gravitational potential energy due to change in it's position
d)gravitational potential energy loses and gets converted into kinetic energy as velocity is produced .
2.A)5 joules
3) The potential energy is same in two bodies as they reached to same height
Came hare after very long time .
And still your videos helps me.
Thanks sir you teach very wellllll💓❤❤❤❤
I hope you give this comment a heart cause It's really easy to understand from some viewers watching your very detailed explanation
We want this man as a physics teacher in our school 🌞
I wish we had RUclips back in 2014.
If we had such teachers back then i would have been an engineer now. I chose science in my higher classes as i loved learning it.. Unfortunately in state boards our teachers only let us cram to score good because thats what actually matters in our education culture.
I am preparing for competitive exams now for which i am watching your videos. I feel so bad kyunki science graduate hone k bavjuud bhi science se zyada acha hold i have in general studies ..... definitions sb cram hai equations etc..... lekin when it comes to practicals it is zero. Thanks to you for making such useful content . You are doing a wonderful job sir ..God bless.❤
I'm also thinking the same.. 😅.. Why we are not having such teachers who explain to make our concepts clear instead of completion of syllabus...I've join coaching for my prep... But here alsoo they don't show practically things... Just teach give examples derive nd move on😅...
The form of Energy are:
1. Elastic potential to Combined Potential and Kinetic Energy going up, when it reaches the topmost part and has its sudden stop before dropping is Potential Energy, and while dropping it again acquires Potential and Kinetic Energy. Finally, when it lands and stop moving, its KE and PE are zero and assumes now Rest Energy.
2. 5 Joules
3. The boy who is in the escalator will reach the the first floor first and so his PE compared to the boy who took the stair will be more than the PE of the stair boy. however, when he also reached the same height of the escalator boy, both of them would have the same PE by then.
Sir you are the best teacher i've seen in the WORLD
1a.elastic potential energy
b.gravitational potential energy
c.kinetic energy
d.kinetic energy
2. 5 joule
3.both are same
Sir i like your videos very much it clears all my doubts about physics
Sir please do reply
C.will also be potential energy since it is at hight. ( i think so !)
4.9j

Wow, thank you!
1Qa) elastic potential energy -compressed spring b)potential energy-ball is at height with velocity zeroc)ball is moving at maximum velocity-kinetic eneegy d)ball produces sound - sound energy 2Q)P.E=5Jouls 3Q)potential energy of both boys are equal because of same mass and height and also acceleration due to gravity is 10m/s^2 thank u for your clear explanation sir jai hind
Answers : 1. a) Elastic potential energy b) gravitational potential energy c) kinetic energy d) kinetic energy
2. 5J
3. Both boys will have the same potential energy ( as it foes not depend on the apth taken to reach to a particular height).
Yes I loved this video I am byjus student but there about this topic there is not perfect but I understood very well in this class tq soo much sir😊
It's my pleasure
Crystal clear explanation and crystal clear concepts
Thanks

Aggressive teaching with examples.Go ahead Manocha Academy.
Very nice explanation 👍👍👍😀
Thanks for liking
Good videos! A couple of details:
1. The gravitational potential energy is not exactly “inside” the hammer.. if we look inside it would be identical to before (elastic energy can be said to be inside the rubber band..looking inside the molecules will be adjusted in various ways). We can imagine some kind of invisible force field between Earth and hammer and so the gravitational energy is stored in this empty space between and nearby.
2. The work energy done by the force depends on only the relatively small displacements of the projectiles meanwhile the force is acting when in contact with the pushing elastic, and is not related to the large distances moved by the projectiles. Once clear of the pushing elastic no more energy is given to projectile of course.
Ur video is full of zest... Mzaaaa aa gya.. Sir.. I thnks to d lord who have given a teacher to me like you..... It seems to b ki ap hi vgwan ji ho...
It's my pleasure
Q.1.(a) totally Elastic Potential Energy.
(b) Gravitational P.E due to hieght.
(c)P.E changes into K.E during down ward motion.But just before it hit the ground,the enrgy was entirely K.E.
(d) P.F and K.E both becme zero as it hit the ground.
Q.2. (5J)
Q.no.3 They will have Equal P.E because it does not depend on the path followed But on the Hieght.
Saw many explanations of potential energy on RUclips, but yours was the best! Very intuitive and easy to understand. Thank you very much🙏
Thanks a lot!! Awesome to hear that :) Do share it with your friends!
I can't express my present feelings through words i mean sir u are another level.🌟💪💪..I was on leave when this part is taking and i was like frustrated..By only watching your video i got this concept really clear thank u so much 😊🙌✨💫
How nicely explained!! Earlier the thing that was not at all clear got into my head because of your help sir. Thank you so much for making this video. 🙏🏻
1) Elastic potential Energy
2) W= mgh
= 0.5 × 10 × 1
= 5 J
3) Both are reach in same time , because energy is independent of path it is only depends on the distance ( s)
Sir you are world best physics teacher. I have no words for your praise

I'm from Tanzania,taking a bachelor degree in BSc,your videos have become very helpful,Keep it on
Glad to hear that
Really!!😀
Q1 - (a) Potential energy
(b) Potential energy
(c) Kinetic energy
(d) Kinetic energy
Q2 - 5 J
Q3 - Both have the same Potential energy
Best explanation video in english for 9th village student. Thanks uuu sir
A)elastic potential then gravitational then kinetic then it comes to rest and no energy
B)500g/1000kg = 0.5 0.5kgx1mx9.81m/s^2 =4.9 J
C)there is no difference in potential energy since it doesn't depend on the path and rather it depends on the height
You are my role model.
Whenever I want understand the real meaning of concepts I came on this channel
GREAT !!!
q1:
a, Elastic potential energy as the spring had the potential to create energy or work.
b, gravitational potential energy as the ball was at a certain height.
c, kinetic energy as the ball is in motion.
d, kinetic energy as again the ball is in motion.
q2: if i take the value of g to be 9.8 then answer is 4.9 joules = 4.9 j
q3: According to the situation we know the height is directly proportional to potential energy so greater is the height greater is the potential energy but in this question it is not mentioned weather the stairs are at a greater height or the elevator, usually in a building both the stairs and the elevator are at the same height so we can say that since both have same height both will have same potential energy.
Can we take g=m because gravity increases with height or we should always take g=9.8m/s²
@@rubichaurasia5003 value of g is fixed 9.8m/s^2 sometimes in question they will provide it as 10 tht time u can take 10 but generally its 9.8
@@alhudatq613 okay I understood and thanks for reply🙂
(a) elastic potential energy
(b) gravitational potential energy
(c) potential energy
(d)Kinetic energy
2.P.E=mgh
m=0.500kg
g=9.8m/s²
h=1m
P.E=0.500×1×9.8
P.E=4.9J
3.the same potential energy
Super explanation sir . I love your class
Thanks and welcome
1 (a) p.e is in the compressed spring( b)p.e is stored in the ball (c) stored p.e starts changing into k.e
(d) k.e is maximum in the ball
2. 5 joule
3. Same as p.e depend only upon
the height and mass.
Such a great teacher I have never seen
Great, your explanation is Easy To Understand.
Glad it was helpful!
I have completed my hs on pure science in 2016, but now I understand what I read past years... You helped ne so much sir...thank you..😇
Finally I understood the concept of potential energy⚡
Your method of explanation is very amazing and better than byju's
Thank sir I first time understood the topic.

Thanks
wonderfully explained through practicals 👏👏
Thanks sir because of you I understand the topic
Glad to hear that keep watching
1a - elastic
1b - gravitational
1c/d - kinetic
2-5
3-neither cause they are same
Mate, thank you so much , I was struggling to understand but now I do.
You are welcome!
I love this video.
The way you explain it's beautiful.
Potential energy
Thank you so much!
(Answer of Q1) (a) elastic potential energy (b) gravitational potential energy (c) kinetic energy (d) sound energy
(Answer of Q2) PE=m g h
m=500g=0.5kg =(0.5 X 9.8 X 1)J
g=9.8m/sq.s =4.9J
h=1m
(Answer of Q3) potential energy depends on mass, gravitational acceleration and height. As these things are the same for the two boys, both of them will have the same potential energy . The path of going doesn't matter in this case.
