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 TH-cam ( 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 ?
S4L4M S43.
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
@@beaulajeevajothijohnrose1847 if it's not given you can take it as 10
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!!

Q1:
A: Elastic potential energy ( the spring)
B: since the ball falls from a height to the table and the ball slows down as it goes up it is Gravitational potential energy
C: as we said in part B the ball slowed down as it went up so height increased. Now in part C the height is decreasing so kinetic energy
Sorry if you didn’t get my explanation
Q2:
PE = mgh
= 0.5kg * 9.8m/s * 1m
= 4.9 joules ( J )
Q3:
I agree with most of the others we need to know which one is higher the elevator or stairs? But let’s just assume they are the same so same potential energy
Potential energy doesn't depend on path taken so same potential energy
@Vijayta Kurtakoti 9.8 is gravity
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.
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.
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.🤐👌👌👌👌👌👌👌
Sir you are one of best teacher in my journey of learning science 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏....
This comment is for all the videos which you've uploaded.YOU ARE THE BEST & GREATEST TEACHER WHICH I'VE EVER SEEN.Thank you so much Sir.God bless you.
Thanks a lot :) Do share our videos with your friends!!
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 ....

your right friend .where are from
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
1
a) elastic potential energy
b) gravitational potential energy
c) kinetic energy
d) sound energy
2) 5J
3) same becuz no depend on pati only hight potential energy depends
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.
2ans- p=mgh
M=500g
M=0.5 kg
g= 10 m/s^2
P= 0.5×10×1
P=5 joule
3 ans is-both have same energy because they are both at same height.
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.
(a) elastic potential energy
(b) gravitational potential energy
(c) potential energy
(d)Kinetic energy
2.P.E=mgh
m=0.500kg

3-potential energy depends on height not on path therefore they have equal amount of potential energy😶
Q1 - (a) Potential energy
(b) Potential energy
(c) Kinetic energy
(d) Kinetic energy
Q2 - 5 J
Q3 - Both have the same Potential energy
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)
I'm sorry but you are teaching better than byjus 😂
Glad to hear that.
He really replyed._. 😂
Tbh u r right
Not better than mangesh Bora sir
That's for sure you are much better than byjus
We want this man as a physics teacher in our school 🌞
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).
Sir you are the best teacher i've seen in the WORLD
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
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.
(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.

At ‘C’ body is falling down so both potential energy and kinetic energy and at point ‘D’ is kinetic energy
1a.elastic potential energy
b.gravitational potential energy
c.kinetic energy
d.kinetic energy

Thanks sir. I understand the topic clearly now and all the concepts.
Glad to hear that
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
a)Elestic potential energy into kinetic energy
b)5 joules
c)both has same potential energy because elevator has elastic potential energy and stairs has gravitational potential energy so they both are one type of potential energy
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

First time pata chala pure TH-cam per koi physical examples lekar samaghya eatane acche se ❤❤❤
Before my concept's are not clear but when I have been watching your videos it's making me easy to understand physics
Great to hear that!! Do check out more videos at www.manochaacademy.com
you are the best teacher from many days i was having the confusion, but the way you explained is just awesome and your english is so fluent and it can be understood, my fav yt channel.
Saw many explanations of potential energy on TH-cam, 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 wish we had TH-cam 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😅...
3. Both the boys will have same potential energy since(as told in the video), the potential energy does not depends upon the path taken to reach a certain height but it depends upon the actual height.
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. 🙏🏻
I hope you give this comment a heart cause It's really easy to understand from some viewers watching your very detailed explanation
Incredible video of a concept my teachers continuously failed to explain!
Came hare after very long time .
And still your videos helps me.
Thanks sir you teach very wellllll💓❤❤❤❤
Crystal clear explanation and crystal clear concepts
Thanks
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..

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
Love it! You did a great job! You've got it be able to so much easier to understand the concept. Physics becomes a lot more piece of cake when you understand their concepts.
Indeed you're born to be a teacher. Your explanation and the example used are so superb. Your teaching is crystal clear. Tq Sir
Your explanation is the best......
Sir How can a body store potential energy in it?
I have always thought real life examples helped a ton with understanding principles !! Thank you so much !! you are awesome!
this made it so much easier to understand. thank you. i usually dont comment on study videos but im a minute in and i already have a better understanding from this video than from other videos
Sir if we take a ball at a height of 4m and it comes at 3m. Here,will we take height as 1m(displacement) or just 3m ?
You are the best teacher 👌👌I have no words to thank you. I ask my daughter to follow your videos before reading book.
Thanks a lot :) You can also go to my website: www.manochaacademy.com and ask her to practice Quiz and Top 3 Questions on each video that is relevant for her.
Thx for the explanation sir! I have a question. Let's say that you lift an object. The potential energy it gets is me giving it energy so I'm losing energy and the object gains it. When I let go for the object it falls down and gives all its energy to to the ground. However if I keep holding it and slowly lower it down the potential energy of the object decreases but where does it go? I slowly lowered it down to the table so it didn't give the table any of it's energy but the object still lost energy. Where did all that energy go? Did I get back the energy I gave to the object?
At point (a)- potential elastic energy (b)- potential gravitational energy (c) potential gravitational energy (d)- kinetic energy

ur teaching method is very effective
Great to hear that :) Thanks!
1-elastic potential energy,potential energy and kinetic energy.
2-5J
3-both have equal potential energy..Because it do not depend on path travelled.
@Ajay Karki, Very good!! Answers of Q2 and Q3 are correct :)
For Q1, you need to identify the forms of energy at 4 places: a, b, c and d. Can you give the appropriate form of energy at these 4 points separately.
A-elastic potential energy.
B-gravitational potential energy.
C-Kinetic energy.
D-Sound energy.
A and B your answers are correct :)
At point C, ball has both height and ball is moving. So it is both gravitational potential energy and kinetic energy.
Point D is just before the ball hits the table. In the video sound comes later. Sound energy is correct answer when ball hits table. Just before ball hits table, ball has only velocity but no height. So at D it is kinetic energy.
those who think the video is nice and awesome 1like plzzzz. sir where do you live?
Q1. I think that there is a gravitational energy
Q2. The potentional energy of the book is 5J cuz if you solve it with the formula its
PE=mgh
PE=0,5kg*10m/s2* 1m
PE=5*kg*m/s2*m
PE=5*J
PE=5J
In question second mass of book will be changed in to 0.5kg . Then h= 1m
PE= mgh
acceleration due to gravity = 10m/s
= 0.5kg ×1m × 10m/s= 5 juoles.
Sir you said that work done
is equals to potential energy stored in the object. Therefore this solution might be correct.
Q,1 = elastic potential energy , gravitational potential energy , kinetic energy
Q, 2 = 4.9 j
Q,3 = same
