Sir Resoect to you for your books!!! Never made life easier than a simpler language from yours.

In short what I learnt is, PE is stored in a system due to its interactions internally. If the charges are opposite and are left alone, they will expend this energy and accelerate towards each other. And same with block and earth.

Is it true for elastic potential energy to

and as a realtime case, as the person lifting object is standing on Earth, he lifts the mass from groud to height 'h', so for the 3-body system: person, object and Earth, the net energy of system doesn't change. For a two body system (Object and Earth), the energy of this system increases by 'mgh' as the work is done on an external agent on the system. The potential energy of system/object increases to mgh while change in potential energy of Earth is negligible or zero.

a message from rochak seriously sir love to see your videos Sir ! High Respect Sir

Thank you very much sir for motivating me to study physics in a new way👍🏼 Sirji please make a video on how to study physics in a good way?

Sir, Great video. Interesting question. Very well explained.

we use + and - as directions also like - is opposite direction and + is with the direction{here direction of force applied by you on the body}

It can be also understood as follows. Positive work done on a particle increases the kinetic energy of particle. Negetive work done removes that kinetic energy and converts it into potential energy.

Sir why voltage remains same and in parallel connection of wires where as current differs why ?

@mukulupadhyay4656

6 ай бұрын

Imagine a water pipe with water flowing through it. If there is a section where the pipe is in parallel, the water should split up and flow into the three different pipes in parallel. Similarly, current divides into the three wires in parallel, maintaining a consistent pressure (voltage) across all branches.

@Savala-Ram

Because all the branches in the connection have same starting and ending point, so all will have same potential difference and so the voltage

Potential difference across the two junction points is same.. irrespective the current diverges or not

@IITBombay576

6 ай бұрын

In parallel combination, the end points are same. Hence, the potential difference between the two end points remain same.

I understood from this video that it is very important to decide the system while applying work energy theorem. Moreover for potential energy which is especially conceptualised for conservative field should also be taken care. Generally people say work done = change in Kinetic energy but work done by whom? Remains unknown unless we specify the force which is responsible for work done. Thank you HC Verma Sir ❤.

Would be a great advisor in astrophysics field.

Internal energy doesn't shows any change due to not change in temperature of particle Kinetic energy doesn't show any changes because velocity of block is same Potential get change because we took it up from a position to height H Truely Legend of his subject we had honour to have luck to seek guidance of sir @HC Verma If we only consider the block change there is no work because mgh + - mgh cancel out each other but if we consider both block and earth potential energy with external force applied by a body the system potential energy will increase with mgh and the work done will happen

Wish you were on KZread back when I was in school

Great Explanation Guruji...

Namashkar sir I am Deepak ,(class 11th) Sir jab hum ik ball ko horizontally ghumate hai apne upar jo ki string se bandhi hue hai to jab wo Puri tarah straight ho jati hai tab tention ko to mrw²balance kar leta hai lekin us samay gravitational force ko konsa force balance karta hai jisse wo ball niche nahi aati

Sir I have a question Does a current carrying conductor has charge on its surface?

Other way to think work done by normal force when you lift the block which will be in direction of movement of the block and we know that since block is not accelerating Normal is equal to mg.

So that means the increament in energy is shared by both earth and the block . So why do we assign it only to the block . Is this because mass of earth is much more than that of the block.

10:32 why internal energy is not changed since system is of two bodies and distance between these bodies is changed as same happen when molecular distance changed so internal energy is changed?

Sir,can we say that body and earth done work on each other which are cancelled,and externally work done by us brings mgh

If you consider earth and the object as 1 system, wouldn't the internal energy decrease by mgh, would energy added still he 0?

Sir my question is when we place a lens in another medium other than air the focal length of the lens will changes but how can we say that the radius of curvature will also change as we have not change the shape of lens and why this all not happens in mirror's case.

Guruji, Pranam Nepal se. 🇳🇵 ❤

your smile is awsome sir

sir achhe se samjh nahi aa paya kyonki ye concept tenth se bahar ka hai par kya potential energy of block remains same but potentional energy due to external force(ie the person moving the block) is +mgh??

Nicely explained ❤❤

Why only external force is responsible for changing the inertia of an object?

Any question's level can be determined when a person with known intellectual prowess is dealing with that question..Simply put, it depends on the person who is dealing with that question.

Sir, in 'light' chapter I learnt that after passing through a mirror or lens if parallel rays are emerged they can meet at infinity. But how is this possible to meet two parallel rays???

@milli3leven377

5 ай бұрын

When something is meeting at infinity, it means that it is never going to meet because infinity is infinite For easy explanation: Imagine 2 parallel railway lines, when you will look into the distance, the tracks will appear to meet at a point on the horizon.This meeting point is 'infinity'. The tracks never meet but the way we percieve distant parallel line makes it look like its meeting at infinity

Greetings sir, Sir I have a doubt that how can we say that moment of Inertia can be calculated as it is a tendency and we can't calculate a tendency.like we don't say it for translation inertia . Love from uttrakhand 🙏🏼🙏🏼

Love you Sir ❤

Sir please explain how current in series circuit is constant because in starting its ampher measurement is different and when it go from one component it is different because some voltage is consume by component but i assume that voltage is know not be zero

Bhai paper Aisa conceptual ayega pass hona bhi mushkil hojeyga fir school bhi😅

This is very underated channel

According to Ohm’s Law, Current is directly proportional to the Potential Difference, but in case of Alternative Current, why the current is inversely proportional to Potential Difference. Why there is contradiction between two expressions:- (i)Ohm’s Law:- Current(I) directly proportional to Voltage(V) But in case of Alternative Current, why the Current is inversely proportional to the Potential difference, due to which energy loss is minimized during the transmission of AC Current at such high voltage(11kV) i.e., Power(P) directly proportional to Current(I) and Voltage(V) =>P=VI =>I=P/V

My question is " Does a charge undergoing acceleration within a gravitational field emit radiation? " I have been thinking about this situation for quite some time since my 11th grade and could not come up with any possible answer. I have also asked this to many physics teachers and professors but could not get a satisfactory response. According to classical electromagnetism, an accelerating charge emits electromagnetic radiation. However this scenario touches upon the intersection of two fundamental theories in physics-electromagnetism and general relativity.
