Honestly you are the best teacher. It's the first time I have seen any Indian teacher to actually TEACH and indulge creativity rather than just preparing for competitive exams. I got fed up with Indian educators due to their non-creative and exam oriented teaching. You are the first one who stress effort on meaning full and actual learning which is practical in real life rather than just cracking exams. This is the way education should be rather than a competitive exam rat race.
i swear all of my brain itching doubts r solved by u sir , its almost like u have a solution to every problem , even the ones other deem as unnecessary and minute!!
Hello, I watched almost all of your videos from KhanAcademy. Even though I'm pretty advanced in physics but your different way of thinking is really interesting. Please upload video related to IIT JEE and Ipho. Love from Bangladesh ❤.
Wow! Need more explanations on conventional notations like why was current considered flow of positive charges and why it hasn't changed even after discovering that it's the electrons moving?
I like your videos even before completing them cause I know they are gonna be a banger, apart from that I consider you my idol 😊 , you're really a great teacher as well as a great personality, I wish my study peers could be like you (prioritizing learning and understanding over marks and ranks) , the pursuit of knowledge is the greatest human endeavor. Sir , I used to and still am very afraid of asking conceptual doubts during class , the reason being teachers never address them they say that's how things are and you must know that much only not why they are the way they are , like once I asked my physics teacher when he was teaching us about projectile motion , " how could the initial velocity of the projectlie be a constant (u) like you said , how can someone or something give it a constant velocity at the start , only while dropping a object vertically from a certain height can we give it a constant initial velocity (of 0m/s) ?" But he laughed and said don't you even know impulse and momentum, and then didn't even address my doubt properly, the answer didn't not make any sense to me , can you help me with this doubt , sir ?, I will be super happy to learn from your perspective 😊
@@Mahesh_Shenoy thanks for replying, sir. I meant to say that if we consider earth a inertial frame of reference (that's one assumption books like ncert, hcv take while teaching projectlie motion) and then consider the motion of a projectlie (object which is in projectlie motion) , then books say a projectile /object has a initial velocity "u" m/s at a angle "θ" with the horizontal (both u and θ are constant) and the projectlie has a downward acceleration of "g" m/s² , now I want to know how can it be possible that the projectlie has a constant initial velocity (of "u" m/s) , like if a object is at rest then it can't just start moving with a constant velocity suddenly , we need to apply force in order to move it (change it's state of motion from rest to moving) , therefore a force must be applied on the projetile to give it a acceleration and thus the initial state of the projetile is : 0 m/s velocity and a downward acceleration of "g" m/s² and a acceleration of "a" m/s² (in the direction where force is applied , since it is a projectile motion we can say that the acceleration "a" m/s² makes an angle "θ" with the horizontal).
@@VyomMath Got it. What do you consider as 'initial'? initial = whenever you start your timer. So it's when the timer shows 0 (and has just started). Since you are free to start the timer whenever you want, you can pick that stone lying on the ground and throw it at some angle. When the stone leaves your hand, we will start the timer and call that velocity as the initial velocity = u. Does that make sense?
@@Mahesh_Shenoy yes I got it now, so the "initial" is when the object has left our hand and has attained a constant velocity "u" in some direction w.r.t horizontal and at this time we start the timer (t=0) and do all the calculations accordingly. The initial velocity is constant because we give it some momentum while throwing, like we swing our arm for some time and in this time the object attains some velocity, then we release it, thus it has a constant initial velocity "u" at t=0, Thanks for clarifying my doubt sir :-))
great video and well explained! i guess you don't want to confuse, but i think it's worth mentioning entropy. in fact it's all about entropy. converting potential energy and dissipating means increasing total entropy. that's what nature does - always. ok, except in some ideal imaginary processes. and that's the reason why less potential energy means more stable. more microstates representing the macrostate. Just for those who wanna dig deeper.
Good morning sir. Sir, I have a very huge doubt about the meaning of potential , potential difference, voltage, emf. Can you please make a video on that paticular thing. My book definitions are so boring and seem a headache to me. Also sir, can you please tell me about some best courses for preparing for JEE ( mains+advanced) and to master PCM. Please sir its a sincere request. My 10th exams are just going to over and I want to take the engineering line and get into IIT.
@@Mahesh_Shenoy Thank you sir, for taking it under consideration.🙂🙂😊😍. Sir, please tell me about some great courses (PHYSICS, CHEMISTRY, MATHEMATICS) for JEE mains and advanced as I will be in class 11 (SCIENCE) after 1-2 months for CLASS 11 as well as CLASS 12.
more energy makes a thing work more or change stataes frequently, when energy reduces that ability to show activity decreases, so energy is low with stabilty
Sir, I have a question in the first places. my question is that why like charges are repeal and unlike charges are attract each other. this question is unanswered for me for a long time. Thank you!!
Great question, here's my philosophical answer. - Imagine playing god where you create lots of universes and experiment with 'different rules'. - You have universes with no charges, charges that always attract like gravity, charges that always repel, and everything else you can think - You then find some universes end up being boring. For examples, universes where there are no charges don't do anything interesting! So no life. - You eventually find the universe in which like charges that repel and unlike charges that attract end up creating some very interesting things -> atoms, molecules, chemical reactions, and eventually life, and then intelligent life that can question it's own existence!
That's the reason Y I hate analogies in chemistry...it doesn't help you understand things but helps to remember things and it kinda gives a false satisfaction that you have understood the reason but no....now gonna binge watch all Ur videos uploaded during my exam...I couldn't watch those cuz of that.😂..I also I need a help...my chem in 11th has been terribly weak...I mean it... it's very weak...any idea how to recover that??one thing is in my coaching they are gonna do the 11th thing again in a fastlane mode for 2 days a week(4days 12th+2days 11th) but besides that any idea?
I've one question in my mind related to "entropy". I have learnt entropy of the universe always increases. In one of the sal's video he explains:- if entropy of some system decreases to compensate that entropy of surrounding decrease with a greater amount making ∆S(net) universe positive. `In case of adsorption of gas the entropy (system) decreases but I'm unable to find any compensating entropy(surrounding) increasing `. Hope you can answer that.
I still don't understand why do we increase the voltage instead of current to supply power from generating station . Cause the same amount of energy should always be transferred no matter what the voltage or current is. Could you explain about this, sir?
hello, sir, I asked you a question in a previous video about the charge accumulation in parallel circuits knowing that each branch is considered to be a series connection but how does the accumulation affect the current out of the branch. you replied that there are several videos on the channel about that but I didn't find them when I surfed the channel. hope you don't find it bothering and thanks again.
I don't find a single reason you have less subscribers.Sir you teach very well.

Good question!
due to the same effect that is caused by the flow of electrons, we can consider conventional current (effect of flow of +ve charge) for ease.

its about heat loss i think

Thank you Mahesh Ji,it is very happy to know that Maxwell is in your list
Sir can u explain how this whole thing works in case of SHM??
how do we relate this with a chemical reaction between atoms, please ??
But there are only 2 types of energy potential amd kinetic energy. Also heat is still a type of kinetic energy. What would you say?
U good
