Sir, Gravitational force is force acting between two bodies when a stone is thrown upwards then earth and stone both of them are attracting each other. But we can only see the stone coming towards the earth at an acceleration(g) of 9.8m/s squared and the acceleration produced by stone on the earth is 1.63x10 to the power -11meter/second squared
actually sir NUCLEAR FORCE is not weak ,rather its stronger than both electromagnetic and gravitationa force but its a short range force its range is approximately 1.5 fermi so its a shortrange force not weak
The nuclear force is not a force that binds protons and electrons but rather holds the nucleus together. It works through the transfer of quarks between protons and neutrons(Just like equilibrium mixture of radioactive sugar and water). This is the strongest force and its effects can be seen among hadrons.
ooh god niten vijay sir ne apne lecture mein bola ki normal is a contact force but this sir is saying it is electrostatic force.....!!! which one is correct ...???
The normal force is not really due to anyof the four force of nature. The forces of nature are not all the forces in the macroscopic sense, they are just the fundamental bosonic particles in a modern quantum field theory description. The normal force is due to the Pauli exclusion principle almost exclusively. This is because electrons have the property that two electrons cannot be in the same quantum state. Two electrons can't be at exactly the same point. But you might be thinking, "two point particles in three dimensions can't ever be at the same point, it's infinitely improbable!" In quantum mechanics, the particles are spread out in a wavefunction, and the condition that they can't be at the same point means that wherever their spread-out-ness overlaps, the wavefunction is zero. The wavefunction is in 6 dimensions for 2 particles, so it is hard to visualize, but the zeros appear on the diagonal part, where the two positions for the particle coincide. When you bring two objects to touch, the electron wavefunctions are squeezed together, and the average scale of variation increases slightly, because of the exclusion. The rate of change of the wavefunction is the momentum of the electron, and as you push them closer, it costs energy. This is the source of the normal force. It would not exist if electrons were elementary bosons.
Sir , Aap plzz har chapter ki videos ko ek sequence m dal dijiye unke video no. Likh KR isse har video k parts ka pta chl jayega ...plzz sir it's a humble request 🙏
Mero ko mistake lag raha h second law ka example me numerical me S ka farmula ut+1/2 at Square hota h to aap pahale t ka jagah par Kuch Nhi maan diye or dusra t ka 3 maan diye Q samaj me nhi aya
Acceleration nikalne ke liye time ki jarurat hoti hai par yahan mass and force diya hua tha isliye acceleratation nikalne ke liye time ki jarurat nahi hai. Sir se galti se likha gaya.
Assalam o Alaikum Sir... Sir why the force and acceleration is always in one direction, and make an angle zero????? why they cannot make an angle 90 or 180 or an another angle.....
Aage ka video kaha h sir plzz upload kr dijiye
Thank u so much sir, i had many doubts in this concept but after viewing your explanations all my doubts are clear now
Excellent teacher u r sir .teaching method is very good . really u r awesome teacher
Even teachers are studying
@@sachinrao484 XD
sir ,I am tenth but it is easy for me to understand ur classes.
thank you very much sir.

Nice
NKC Sir can't u upload whole topic on the subject.
nice sir..... but apne laws detailed me nhi bataye jo (inertia, chainge in momentum)1 2 law me jaruri hai.
Padhane ka tarika bahut achha Laga.
actually sir NUCLEAR FORCE is not weak ,rather its stronger than both electromagnetic and gravitationa force but its a short range force
its range is approximately 1.5 fermi so its a shortrange force not weak
Subham Dubey misunderstanding it is 4th
then isnt it weak
No its not weak bcoz it keeps neutron and proton together in nucleus of an atom
Subham Dubey you are mad
Adnan Khan fuse hang St jug
Newton's law ko bahut achcha samjhaya hai
I am in class 8 but he made me understand a so much hard chapter which he was actually teaching to IIT AND JEE students
Your teaching method is very different than others . It is very easy to understand so thnx sir
These topics are generally learnt by NSEJS aspirants in class 7 only...
Bahut sundar jaankari
Totally conceptual lecture
Sir you teach very perfectly I'm greatly inspired by you
I understand all the law s of motion it's easy to understand

Sir, they are also a force
1) component of force
2)contact or non-contact force
Can you explain this forces??
Thanks for you
Sir thank you so much. It was very useful
without force body can change its position. for example when it moves with constant velocity. force changes the frame of refrence of a body.
You way of teaching is amazing
Sir, at 21mnts question ,force applied on the body is just 20N , but mass is 5kg then F=mg=49N. 20N is less than 49N, then how will block moves.
Measurement of an object insertion is- a) mass. b) force. c) speed. d) momentum

Old is gold 💖
sR..are u really great...best teacher of physics...i mostly like u sR...really great.👌👌
Thank you for dis video
It really helped me a lot
Great sir..
ooh god niten vijay sir ne apne lecture mein bola ki normal is a contact force but this sir is saying it is electrostatic force.....!!! which one is correct ...???
nilakshi sahariah correct vai...i am even being confused by sooo manyyyyy concepts....now....
Hey guy all contact forces are electromagnetic in nature.
Bhut aacha hai sirjee lecture
Wow sir aapki drawing kitni achii haiii👍
Bahut accha
Sr then from where we are getting normal reaction
Sir you teach really awesome thank you so much this video is very use
Hpu
i like the way u teach and please continue for us
awesome Sir.... teaching method is very gud
sir agar gravitation force khatam ho jaye to hamare uper kitna types ka force act karega....
very good video. i can understand three laws of motion easily after seeing this video
You are my favorite teacher
sir ap bhahut acha padate hai motion under inverse sqaure law ki video dale sir
Kya hum gravitational Force generate kr skte hai.... Jo insaan ya Kisi bhi vastu ko Apni or kheech ske....
Hello sir I am in 10th standerd . Your teaching method is too good .
wow what a teaching method
Sir I have a confusion what is this arrow sign above the units. 😕
Sir appka padhane ka tarika bahut achha hai
Abhishek Tech yes you are right
ha yaar
d kg to her v dry
Abhishek Tech
superb explanation sirji,..
Best teaching pattern sir
Wah sir aap bahut accha padhate h. Thanks sir. Sir aapka drawings bahut accha hai
Sir u re teach best in the world
Sir ,I am in class 7 but ur teaching style is very best
Bahut achha se apne samjhaya sir
How normal is electromagnetic force?Please explain it
Mast video hai sir.👌 Thanks for sharing. I like your way of teaching 👌👌.who gives you 68 dislikes. I don't like it😠
You are my favourite sir.
How to defined Newton's first equation of motion when read new session to final session.
Please describe newton 2 law with momentum
Good manner of teaching Thanks
thanks sir aap padhathe bahut acha hai mujhe bahut acha samajh aaya
Ty sir👍
Sir 'N' electromenetic force kaise h
Sir wall ke particles kaise push kaisa hoga

I reguest you that please complete make full chapter
Acceleration=change in velocity
V good leacture sir
Very nice keep it up
Helpful...thank uhh
Sir gravitational force and weak force is same
Thank you Sir😊☺
Gajab hai sir
Mero ko mistake lag raha h second law ka example me numerical me S ka farmula ut+1/2 at Square hota h to aap pahale t ka jagah par Kuch Nhi maan diye or dusra t ka 3 maan diye Q samaj me nhi aya
Bhai ye question mai distance nikalne ke liye time ki koi jarurat nahi hai sir se galti se likha gaya hoga
Acceleration nikalne ke liye time ki jarurat hoti hai par yahan mass and force diya hua tha isliye acceleratation nikalne ke liye time ki jarurat nahi hai.
Sir se galti se likha gaya.
Sir 10 Sept ko bhi thandi rahti(upload date)hai
Good teacher
Balance force or unbalanced force explain kare sir please
How it electromagnetic force
Thanku sir...
Shams Hassan 😀
I Love U
👌
good teaching sir
Wow v nice tomorrow is my interview its help me a lot thank u so much
F=ma is not second law rate of change of momentum is 2nd law.
Outstanding
Assalam o Alaikum Sir...
Sir why the force and acceleration is always in one direction, and make an angle zero?????
why they cannot make an angle 90 or 180 or an another angle.....
please bro full video ...
