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
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
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.🤐👌👌👌👌👌👌👌
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.
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!
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
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
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.
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.
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
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
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 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 😊🙌✨💫
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.
(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. 8
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.
Thanx,sir.I am really satisfied.I am a 12 grade student from Bangladesh.I am very passionate about physics.This video has answered my questions properly.
ur the best sir no doubts about tht.... hope ur my next year class teacher..and i just bought ur physics course sir JUST AMAZING SIR ...... read for exam from ur physics course sir
Sir the answer of the first question is a.elastic potential energy b.it has potential and kinetic energy c.it has potential and kinetic energy and last it has potential and heat and sound energy and 2 nd question 5 joules and 3 rd question is they have same potential energy because potential energy does not depend on the path of travel .. Thank you sir
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
1. Potential energy 2. 500g converted to kilograms (kg) is equal to 0.5kg, height is 1m , and gravity is 10. Use the formula PE= mgh, 0.5x10x1= 5J 3. Boy B
Hello comrade in arms. I mean to say I also teach physics, and often share RUclips videos with my students. Why reinvent the wheel. Yours are among the best if not best, specially for introducing concepts.
1) a. PE (elastic) b. PE (gravitational) c. KE d. KE 2. (500g)(0.001kg)(10m/s^2)(1m)=5J 3. Boy "A" and "B" will get the same PE because the height and their masses are equal.
No at point 'd'the ball will not have kinetic energy because it is on the maximum height and when a particle reaches the maximum heigh then it starts to move down towards the earth due to acceleration ( basics kinematics) and you would learn in kinematics that at maximum height the final velocity of the particle becomes zero so it has zero kinetic energy too and since the ball is on some height so it has gravitational potential energy. Hope you got it 😊😊
@@rittikashaw134 yes it was my brother's reply he is in 5th and is in 2 stage of tallentex and also me. I studied it yesterday and he did it around 2 months ago so it was his opinion and he is so small for class 9 material so it might be that he is copying him.
1] A to D it has elastic P.E B to C it has K.E due to motion [2] P.E of the book is 4900j [3] Both have same P.E as P.E depend only on hight reached and not on the path taken 🥰

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

Q1=elastic potential energy and gravitational potential energy Q2=5J Q3= they get equal potential energy
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.
(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.

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.
Crystal clear explanation and crystal clear concepts
Thanks
Thanks Sir, we are much more grateful to you!
a)elastic potential energy
b)gravitational potential energy
c)potential energy
d)kinetic energy
Mass=0.500kg
H=1m
G=9.81m/s2
P.E=m×g×h
P.E=4.9 joules
What about 3q bro
@@kethinenivasu1525it will be same because they height reached at the end is the same and the path taken doesn't matter even if its longer or shorter
Your method of explanation is very amazing and better than byju's
Jr tutorials and you are my favourite study RUclips 🌟 star ♥ ❤❤❤
Wow, thank you!
Thanx,sir.I am really satisfied.I am a 12 grade student from Bangladesh.I am very passionate about physics.This video has answered my questions properly.
You are most welcome
Is ur channel only about physics.?I love physics very much,want to pursue higher studies in it in future.
Thanks sir because of you I understand the topic
Glad to hear that keep watching
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
You are my role model.
ur the best sir no doubts about tht.... hope ur my next year class teacher..and i just bought ur physics course sir JUST AMAZING SIR ...... read for exam from ur physics course sir
All the best
Sir the answer of the first question is a.elastic potential energy b.it has potential and kinetic energy c.it has potential and kinetic energy and last it has potential and heat and sound energy and 2 nd question 5 joules and 3 rd question is they have same potential energy because potential energy does not depend on the path of travel .. Thank you sir
Thanks to you for answering these questions....
fabulous explanation all doubts are cleared but please try to watch at 1.25x or 2x it will save your time
Mate, thank you so much , I was struggling to understand but now I do.
You are welcome!
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
You are completely outstanding Sir.
Thanks
Such a great teacher I have never seen
1. Potential energy
2. 500g converted to kilograms (kg) is equal to 0.5kg, height is 1m , and gravity is 10. Use the formula PE= mgh, 0.5x10x1= 5J
3. Boy B
Bro answer no.3 is that they will both have same PE as it does not depend on the path taken.
Thanks you sir for teaching me conservation of energy
Hello comrade in arms. I mean to say I also teach physics, and often share RUclips videos with my students. Why reinvent the wheel. Yours are among the best if not best, specially for introducing concepts.
Thank you sir , it helped me a lot .
Glad it helped
Sir you are the beat teacher in the world thank you My all douts are clear thank you very much
Yes
Q,1 = elastic potential energy , gravitational potential energy , kinetic energy
Q, 2 = 4.9 j
Q,3 = same
Sir please reply me sir....i tried my own ... after listening your class....
also heat and siund
Only your video could satisfy my mind... 🙏🙏
Sir thank you making the concept so clear.. Hats off to ur effort.. Learning physics was never fun but now it's different
Awesome to hear that :) Thanks!! Do share the video with your friends!
Sir really helpful thanku i can, t understand while my teacher took class after seeing ur video full clear
1) a. PE (elastic)
b. PE (gravitational)
c. KE
d. KE
2. (500g)(0.001kg)(10m/s^2)(1m)=5J
3. Boy "A" and "B" will get the same PE because the height and their masses are equal.
yup you are right
No at point 'd'the ball will not have kinetic energy because it is on the maximum height and when a particle reaches the maximum heigh then it starts to move down towards the earth due to acceleration ( basics kinematics) and you would learn in kinematics that at maximum height the final velocity of the particle becomes zero so it has zero kinetic energy too and since the ball is on some height so it has gravitational potential energy.
Hope you got it 😊😊
@@rittikashaw134 yes it was my brother's reply he is in 5th and is in 2 stage of tallentex and also me. I studied it yesterday and he did it around 2 months ago so it was his opinion and he is so small for class 9 material so it might be that he is copying him.
I like your teaching style sir. You are my favourite teacher for physics.
Thanks a ton :) Do share the videos with your friends and family!
a) elastic energy
b) potential energy
c) Kinetic energy
d) gravitational energy
I love this video.
The way you explain it's beautiful.
Potential energy
Thank you so much!
1] A to D it has elastic P.E B to C it has K.E due to motion [2] P.E of the book is 4900j [3] Both have same P.E as P.E depend only on hight reached and not on the path taken 🥰
its 4.9 joule😀 convert 500g to 0.5kg
Set into brain 🧠. Thank you sir. You gave feel of the potential energy.
Great, your explanation is Easy To Understand.
Glad it was helpful!
You are the best sir thank you and may God bless you 🙏🙏🙏
