Sir though some may say that your community is small, But the impact that you make is immense Thanks

[@adamjaromi5510]

I hope you will continiue making these very helpful and understandable explanations. Your work should be apreciated more!

[@PhysicsMadeEasy]

Thank you very much Adam, I appreciate your kind words!

​@@PhysicsMadeEasy Sir, If I place my hand flush against the wall and try to push the wall, does it mean I am applying force on the wall. Since FORCE = MASS X ACCELERATION ACCELERATION = VELOCITY / TIME VELOCITY = DISPLACEMENT / TIME Since there is no displacement between my hand and the wall therefore velocity becomes 0 and as a consequence Acceleration becomes 0 and hence Force becomes 0. So does that mean I am applying 0 force on the wall ? Am I right or wrong Sir, please explain where I've gone wrong if I did. I searched a lot on the Internet and KZbin but didn't find satisfactory answer for situation mentioned above

[@PhysicsMadeEasy]

@@md.uzairahmed7774 Hi, Your confusion comes from a misunderstanding about the second law of Newton, when you write F = M*A, F is a force equal to the sum of all the forces on the object of interest, also called the net force. When you press your hand against the wall : What are the forces on your hand ? The force coming from the muscles in your arm towards the wall, and the reaction of the wall on your hand. Sum of forces on your hand = 0, Fnetonhand = 0, Ahand = 0 What are the forces on the wall ? The force of your hand on the wall, so that makes the wall push on the ground in the same direction at the level of its foundations. So there is a reaction force from the foundations on the wall. Again, sum of forces on the wall = 0 so Awall = 0 I hope this helps !

Keep up the great work!!!

[@allpurposeconstructionwiz]

Could you make a video about what matter is so much confusión

[@PhysicsMadeEasy]

That is a large subject haha! But basically matter as an assembly of fermions (quarks and leptons), or more profoundly a form that can take energy. I like to see it as crystallized energy.

[@DeltaAlpha00]

This is incredible, I feel it has a great balance of theory and proper concept! On a side note, could you make something related to why an electron has a negative magnitude of energy? That would be highly appreciated!

[@PhysicsMadeEasy]

Thank you so much for your kind words. I am glad you appreciate my approach. Regarding your comment: an electron does not have an intrinsic negative magnitude of energy. The energy of an electron depends on its position, in other words, where it is located compared to other charged particles. If it is close to other negative particles, it will have a positive energy, because energy was provided to the electron to bring it there. If it is close to positive particles, it will have a negative energy, because the electron provided energy to get there. More formally, the energy of a particle is its charge multiplied by the electric potential where it is located (Energy = qV). The charge of an electron is -e = - 1.6*10^-19. Close to negative particles, the potential is negative so PE = (-e) x (-V) = eV > 0. Close to positive particles, the potential is positive so PE = (-e) x (V) = -eV < 0. (PE stands for electric Potential Energy of the particle) I hope my answer helps :-).

Well explained. Thanks for this

You are welcome Jones.

[@vidhandoshi6623]

Sir you help me understand the concepts very well. Others just tell the name and formula but you make us understand and visualize that term. Its my request sir can you please explain Electric Dipole

[@PhysicsMadeEasy]

Thank you for your encouraging words! A video about Electric Dipoles? I actually have produced one already! The video "What is a magnetic dipole moment" presents the subject by explaining first what are electric dipole moments. The full first five minutes of the video are about electric dipoles: kzbin.info/www/bejne/oniUhYNrYtd-nK8

[@vidhandoshi6623]

thank you sir

[@joeg3536]

@physics made easy : I feel the use of word 'Time' 'Clock' in relativity is the source of all confusion for layman. Will you be able to let us really know how go look at this differently from a day to day life's physics that we are familiar. For eg; if im right photon in its frame of reference doesn't experience something, but a detector does experience something, and all this is because of something described in relativity frame work. So what's this something and what's going on and how to look at it. What's the problem statement? ..

So to make it clear to me: if I am driving in my car I am traveling back in time in an unnoticable amount of time?

[@AndersVossBülow]

No, you are not traveling back in time. You are traveling forward in time. When you experience to have driven e.g. 10 seconds, 10 seconds will actually have passed for you. But for an observer on the sidewalk there will have passed a tiny bit more than 10 seconds. For both persons time only moves forward, and nobody is going back in time.

Thank a lot ,Sir.

[@npjay]

I never understood why they use this example to explain, its kind of a math trick, from alice frame of referance bobs clock is dilating and now from bobs frame of referance too alice's clock should also dilate by the same amount as both are moving away ftom each others initial frame of referance at the same speed...!!

[@PhysicsMadeEasy]

Yes that is correct even if pretty counterintuitive. The flow of time in reference frame A as measured from frame of reference B dilates, and vice versa. This is called the twins paradox: If A and B decide to meet and compare their clock, which clock will be in advance to the other? Well in order to meet, they will have to accelerate (or decelerate), which will make the frames of references stop being inertial... so here, the paradox just breaks down, as special relativity would not apply anymore.
