This is not deriving. U just stated the formula without proving it

[@skeletonrowdie1768]

here khan acadamy actually derives it: kzbin.info/www/bejne/jpumdqijoa91pNE

[@mrmoxx7820]

Thnx dude

[@Hino_55]

"Any change in the velocity (whether it's a change in magnitude OR change in direction), implies acceleration."

[@StudyTrekVlogs]

Nobody made me understand like you did, 😊 thanks

[@theeggsquidzidboi7324]

For anyone wondering "where is the derivation of a = v² / r", Khan already derived in another video. Easy to search it up for his visual proof.

[@f.a...3061]

Yes I confused 🤔

[@madhut3006]

Thank u for your great information sir

[@arnavkhatri1483]

Can we use vw as a formula for centripetal acceleration?

[@jackson570]

yes. w * v = w * wr = w²r

[@sharmabrothers3656]

please derive for centripetal acceleration first

[@qualquan]

Why so many videos on this topi?. Best was the calculus derivation of centripetal acceleration. Nothing derived here.

[@cuberpianist3269]

Awesome

[@varunahlawat9013]

-_- I was looking for the derivation not just using V^2/R ATLEAST GIVE REAL TITLES TO YOUR VIDEOS (IT'S ANNOYING)

[@leif1075]

WA9T TECUBICSLLY SPEED IS CHSNING IN THE COMPONENTS AT EVERY MOMENT Y COMPONENTN OR X COMPONENT OF VELOCITY IS CHANGING so in thst sense they are changing!!

[@amologusmogusmogumogu2535]

Mr. Khan , please help , If the proton and elecron in a helium is attracting each other , why doesn't they bump together instead of the electron to move around the proton ?

[@kisiki_kt_na_lage]

This is the same reason why Earth doesn't collide with the Sun. Basically the electron is revolving at such a great speed that the attraction of the proton is just enough to hold it inside the orbit.

[@saiprasadhakki]

1. Electrons have negligible mass 2. There exist *Neutrons* covering the protons and preventing collision 3. The Coulomb's Electromagnetic Force is less *You might want to learn more about Coulomb's Law*

[@akashagnihotri2469]

Both the previous comments are incorrect. They have some facts but don't actually explain why the electron does not collapse into the nucleus (or protons). The actual reason is because of Heisenberg's Uncertainty Principle: - The electron does NOT orbit the nucleus like a planet orbits the Sun. It behaves more like a probability cloud that exists in shells and "orbitals." Do not get confused by the name. - Now according to the Uncertainty Principle, the position and momentum of a particle cannot be known simultaneously with perfect accuracy. Formula: (uncertainty in position) x (uncertainty in momentum) > Planc's constant. - With these two things in mind, if the electron were to collapse into the nucleus, it's position will become definite. Furthermore, it's momentum must be 0 because it has collapsed into the proton. But now we know both the momentum and the position, which is NOT allowed by the uncertainty principle. This is a rough explanation and you will understand this better when you study Modern Physics and quantum or particle physics in University. Read more about Zero Point Energy, Bohr Model (and why it's incorrect) and Atomic Stability.

[@champaklal3178]

Shielding effect

[@MaulikSrivastava]

The said attractive force is perpendicular to the direction of motion of the electron at a given instant. So, it undergoes circular motion. i.e the attractive force acts as the centripetal force What I said isn't incorrect, but when you consider orbitals and the uncertainty principle, things become weird. So, to get a basic idea, what I said was correct
