Thank you. After not being able to understand this in school, college, university & home .. now I finally understand it after 35 years. Very very grateful
@@joydeepsingh9113 bro he told logic in video. Postive means we move to right on number line. Negative means reverse, so reverse of right is left. But 2 times negative is reverse of reverse, ie straight, that is right side on number line. Like what happens if you take U turns 2 times? You end up in your first direction. Think of negative sign as a u turn
In school our teachers... Be like - × - = + + × - = - - × + = - + × + = + Ise rat lo.. Ajj rak rata hua hi tha but ajj sir ne sara concept clear kr diya.. Thnq sir.. Teachers like you are very rare.. 🙏
Sir please continue such type of videos! These are very helpful for me. Mujhe kbhi nhi pta tha is ke bare mn bss yahi ratta lgaya hoa negative negative positive blaa blaa. Real Math smjh a rhi!❤️👍
Bro,Carry in addition is a kind of formula for addition which can be proved on number line Same as (-)×(-)=(+) is a formula for multiplication which is proved by our sir in this video.....💗💗💗
Sir please answer my some queries 1) why mass of atom of element determine it's physical properties. 2) why no. of electron and proton in atom of element determine it's chemical properties 3) why isotopes of elements become radioactive due to presence of extra neutrons in their nuclei
SIR, We know that 'To every action there is equal and opposite reaction' If it is so then if we consider a collision in which a object is stationary. Let us consider a object in motion as O¹ and stationary object as O² where both have same mass then In this collision O¹ will exert a force on O² which will cause a displacement i.e work is done on O² by O¹ But according to 3rd law O² will also give some reaction which will cause a displacement in O¹. But we observe all the energy which was given by O¹ -> O² was again given to O¹ in form of reaction. So how does O² move if all energy was taken and again given away by O² to O¹
O¹ has momentum as it is in motion so the force applied by O² by N3 law is used up in making the O¹ stop and thus they both show bit motion and stop after collision- mass of both is noted in it
O2 does not give energy to O1, it applies a reaction force. If O1 doesn't move at all after the collision, this reaction force hasnt performed work (no displacement), and hence there is no energy transferred back to O1.
Action reaction force doesn't cancel each other... So both of the object have experienced same force but as O1 had also some velocity so effect on it observed by us is 0... But before displacing o2, O1 overcomes that reaction force..
Not defined and undefined is same thing e.g 0/0 is undefined ..............infinity means take a largest positive no. Then add 1 to it u will get a more positive value
Sir in some said that pressure in fluid is due to their random motion and some said that it is due to gravity but while deriving formula we only consider gravity
Hi ma'am, I found this comment after 2 years, and it is a really Interesting question. I am leaving my answer for everyone going through this comment. yes, the pressure exert by the fluid is due to the motion of their particles, and when fluid act in the influence of the gravity then the particles don't have random motion, the resultant vector of all the particles point towards the downward direction. That means in the influence of the gravity particles of any fluid tends to move more toward the downward direction. so, That is the main reason why we consider gravity if deriving the formulas. Thankyou
It actually depends on which pressure you want to consider.. the pressure you first mention is pressure due to the molecular interactions between the molecules and the wall of the container..... But the second pressure you mention is due to the weight of the liquid... Inorder to find out the molecular distribution of the molecules we have to go through the intramolecular pressure.... But for normal classical problems like pressure exerted by liquid we have to know its pressure due to weight

Sir i am very confused about the concept of posotive and negative work.We know that when we throw an object upward then we applied the force on object in upward direction and body also moves in upward direction so in this case the work must positive but in text books it is mention that work done will be neative in this case.Sir plz explain this misconception.i will be very thankful to you sir❤❤

Question : Any Object Other Than Mirror Scatters light in Different Direction Then How Can Our Eyes Able To see This ... As It Doesn't Fall on our Eye Directly
Anamoly of Mathematics.... When negative 2 has to be added twice negatively, (-2 x -2), then the journey on number line would be 0 to -2, then -2 to 0 then 0 to +2. It can not be +4.
Sir , What is actual meaning of time , and why C=Frequency*Wavelength ? Is flow of protons possible , can we make any proton move , if yes then what will be the difference between electric and proton current ? Can electric current flow in vacuum through any conductor .
I really apologise for my mistake sir , I have realised my mistake sir , please forgive me , you're one of my best Physics teacher , I did that only because you could see my doubts , nothing more than that , please take my doubts sir 🙏🙏🙏
@@edupoint.secondary My future aim is to be world's best scientist , that is why I tagged myself Prof. You're one of my inspiration , being honest my doubts are cleared so far from your incomparable lectures and video series that no one can provide without any dollars , please forgive me sir , I didn't do that intentionally , I wanted to know their answers only
Sir, नंबर लाइन पर तो आपने बहुत ही अच्छा समझाया लेकिन अगर हम गुना की परिभाषा से इस बात को सिद्ध करना चाहे की multiplication उसका repetitive sum होता है. As 2×3=2+2+2, then -2×-2=?
sir can s=1/2 vt can also use as eqaution of motion sir if possible then why we can not use this eqation. if we do not change v-u=at then s=1/2vt. sir plz tell
There is nothing.... First multiply ✖ the two numbers by not observing sign.. Then if you see there any - negative sign then the product will obviously negative. This is simple... Nothing to worry

Thank you sir... 🙏🏻
Wow wow what a crystal clear explanation 👌👌👌
Ohhh
So anything negated 2 times is postive🙏
Thanks a lot sir..
If negated 3 times, it's negative...
but why ? what is the logic .. that no one explains

Postive means we move to right on number line.
Negative means reverse, so reverse of right is left.

Sir i love your teaching method you are a genius
In my childhood i asked this doubt 50 members above all are class first rankers 😃😃😃 no one given answer
Simply laughed
You are the excellent sir 😀😀😀😃😃
At that time, did you know the answer???
@@Venom-xy6cs no
It is really good for teachers to know. Many teachers hardly give this practical geometric technique to students in primary clssses.
Sir please answer my some queries
1) why mass of atom of element determine it's physical properties.
2) why no. of electron and proton in atom of element determine it's chemical properties
3) why isotopes of elements become radioactive due to presence of extra neutrons in their nuclei
Sagar, video is available for first 2 questions.
For third question you have to visit EduPoint and have to watch the videos of the chapter 'Nuclei'.
Thank you sir got my answer
Sir, Aap ne mere saare doubts solve kar diya . thanks
सर आपका बहुत बहुत धन्यवाद
Very informative video.
Thank u sir I am physics teacher but daily I am learning to u
🙏🙏
there is a very simple logic to understand this : the enemy of my enemy is my friend
Dear sir, your explanation is an eye opener. I had never thought of such a great explanation. We need more thinkers like you. All the best.
SIR, We know that
'To every action there is equal and opposite reaction'
If it is so then if we consider a collision in which a object is stationary.
Let us consider a object in motion as O¹ and stationary object as O² where both have same mass then
In this collision O¹ will exert a force on O² which will cause a displacement i.e work is done on O² by O¹
But according to 3rd law O² will also give some reaction which will cause a displacement in O¹.
But we observe all the energy which was given by O¹ -> O² was again given to O¹ in form of reaction.
So how does O² move if all energy was taken and again given away by O² to O¹
O¹ has momentum as it is in motion so the force applied by O² by N3 law is used up in making the O¹ stop and thus they both show bit motion and stop after collision- mass of both is noted in it
O2 does not give energy to O1, it applies a reaction force. If O1 doesn't move at all after the collision, this reaction force hasnt performed work (no displacement), and hence there is no energy transferred back to O1.
Action reaction force doesn't cancel each other...
So both of the object have experienced same force but as O1 had also some velocity so effect on it observed by us is 0...
But before displacing o2, O1 overcomes that reaction force..
Absolutely what I'm teaching is , what you said..... 🙏🏻🙏🏻🙏🏻🙏🏻
We learnt in our schools, and our teachers were very good explaining basics
Wow nice explanation ❤
Simple stuff, but not everyone can explain this well. Keep it up! It will help millions of people.
SIR DIFFERENCE BETWEEN INFINITY AND NOT DEFINED OR UNDEFINED 🙏🙏🙏
Nothing they are all same since infinity is undefined
Not defined and undefined is same thing e.g 0/0 is undefined ..............infinity means take a largest positive no. Then add 1 to it u will get a more positive value
