Hello there! I'm Vishesh. You know, my decade-long stint at 3M taught me a lot: from sticking things together to realizing I couldn't resist the gravitational pull of physics education! The brilliance of educators like Sal Khan, Hank Green, and Derek Muller was like the North Star during those corporate nights.
Now, swapping meetings for blackboards, I'm on a mission to craft content that's rich in knowledge, has stunning visuals, and articulated with clarity. Physics isn't just formulas; it's a captivating tale, and I'm here to unravel it with precision..
So, ready to join me on this cosmic journey? Let's dive deep into the wonders of Physics!

How to find accn eqn
Not sure what your questions is? Please elaborate
sir why we have taken this direction can i take any direction for the current
Yes Aswin, you can take. The final result will tell you if the presumed direction was correct or incorrect
Why are F1 and F2 in opposite direction?
I understand F1 must be a force provided by a pump and the direction would be towards the right, but what is providing F2 and why is it in the opposite direction of F1?
Does the pressure change if water inside start moving around? (Like if the table the aquarium was on got hit and cause the water inside to splashing around.)
While sloshing causes instantaneous pressure variations, the average pressure on the aquarium walls, when averaged over time, does not change significantly from the static case.

Could we think of it as a = + 5m/s i since motion is only along i direction
Absolutely correct. However since it is in i direction only, we just write +5 m/s or -5 m/s as the situation may be, without putting i. But we can put i as well, it would be in place
@@TheScienceCube Thanks for help! I really struggled with understanding it since it’s never mentioned anywhere in textbooks!
@@Timetraveler0161 Great to know you understood. Are you preparing for an exam?
@@TheScienceCube Not really… I am self taught, but I struggle with vector notation. I wanted to learn everything in detail, but what confuses me is things like negative Coulomb force? Or velocity being negative. Magnitude? It can’t be negative. Only the x, y and z components. It’s not clearly explained in textbooks, but rather randomly thrown in

Are you asking a question? Please clarify
🧡
I don't know what did I do, but I just imagining holding rope at T1, so i felt holding 10N force, means 1kg mass (g=10)...similarly, i imagined holding rope at t2, then i was holding 40N force, means 1kg below box and a 3kg box that is applying 30N.. Basically, i solved it practically, 'cause writing equations gets tricky idk why
Very nicely put! You are absolutely right. However, this Q&A is more about improving conceptual understanding. So then if one is given a problem where the system is accelerating, you can use the same equations and put the value for a instead of 0. But of course you seem to have a natural flair for the subject :)

I found Vishesh sir's channel with my teacher's help (Sir Ashish Shekhar, chemistry teacher, Aakash Institute). The videos make it fun for me to tackle physics problems. The videos help me a lot in my NEET preparation. The animations and sir's explanation along with it helps a lot in building the skill of solving tough physics questions. I appreciate the efforts put into the animations and editing part. Thank you so much for creating amazing animations for us to comprehend stuff easily!
Do you accidentally have "Y = Zero = Max Stretch" and "Y = Max = Zero Stretch" backwards? At Y = Zero the simulator was a Rest = zero energy added... therefore isn't "Max Energy Added" at Y = Max?
What time of the video are you suggesting?
@@TheScienceCube Sorry @3:15 - When talking about the spring. It might be a theory representational thing which I am missing. But if you stretch a spring from rest to Max would it not have Max Energy.
@@TheSecrecyOfFrequency I get it! When you stretch to the max...you see at the max point it is at rest, so the KE is zero...but it has a lot of PE, or in other words potential to snap back.
You're right, I would've done that mistake too lol Thank you so much for this video!

Great to know! What class are you in?
i have a doubt if i connect 3 same bulbs in series will all the 3 glow with same intensity of the 1st one will b brightest. doubt is will the voltage equally divide bcz I read somewhere that the last bulb will glow the least
The way you should see the situation is that you have introduced another resistor in the circuit. This means you are blocking free flow of electrons. So the current goes down across the series. However I will still be the same for each bulb since electrons have only one path to pass through. So lower current means lower glow for each of the 3 bulbs, but equal
Before reaching max height, the horizontal component of velocity vector is acting upwards, hence taken positive. But after crossing the maximum height, the horizontal component of velocity vector is acting downwards. So it should be taken negative right? (i.e +V during upwards motion, and -V during downwards motion?)
You mean the vertical component?
@@TheScienceCube yep
@@TheScienceCube Yeah, after crossing max height, it should be like (-V) = (Vo) + (-g)t. right?
@@karunareddy6966 ..but you have written horizontal. Yes that is entirely correct. See the notation that we usually follow is that any vector pointing in direction of +y axis is positive and any in +y direction as negative. That is the reason g is always negative.
Hmm, I strictly support this point. But many educators disagreed saying it will eventually become negative. SO summary is : for upwards motion : Vertical component is : V = v0sin theta - gt for downwards motion : Vertical component is : (-V) = v0sin theta - gt but, it many reference books like many famous books of kinematics generally prefer saying Vertical component is : V = v0sin theta - gt for whole projectile path. why is that so?
