Harmonic Oscillators in Physics | Potential Energy Analysis

[@asthatiwari2648]

teachers like u motivate student to pursue Physics :-)

[@fancuboid2712]

Woow thank you sir.... We need more video like this.....

[@DrDeuteron]

it's not just physics, it's also many fields of engineering. You need to master the damped, driven, coupled multi variable harmonic oscillator, classically. In quantum mechanics, it's key for introducing bra/ket notation and ladder operators.

[@amritsagarkar7899]

Seems quite easy but the very realisation of this idea in a kind of unified way is awesome........

[@subhajitmanna9236]

Very interesting session. Thank you sir.

[@mariommamtaj3624]

Very enlightening. Thank you, sir.

[@siva-ok9qk]

It's very interesting sir. 16:36 😊

[@TANUJKUMARPandey9999]

Very cool and awesome video 😍 Thanks a lot

[@ysrsso]

We are lucky student because we have you sir .

Hi Profesor. The second derivative of V should also be evaluated at x = 0 if you decide to take the origin at that point. Isn´t that so? Please...

[@FortheLoveofPhysics]

Yes. Essentially, x0=0, that's the assumption I made

[@pauldirac6243]

@7:27 you set V(xo) = 0. How? First, it's not affected by the derivative, which sets V'(x)=0 and, second, V(x0) is showing a non-zero displacement value in the graph to the right?

[@johnitaballmer3966]

By a change of coordinates. If you shift the origin of your coordinate system to be the minimum of your potential, then x_0=0, and V(0)=0

[@FortheLoveofPhysics]

The displacement to the right is because of a non-zero x0. Since x0 merely defines the equilibrium position, we can set it to zero as most times that's what is done. Same with the y-axis which signifies the reference from which potential energy is calculated, for eg. the potential energy of a pendulum can be calculated from the ground or ceiling, or the lowest point of motion. It's a matter of convenience, and these additive constants donot affect the nature of potential/force/motion etc

Thank YOU so much

[@kashifnawaz9127]

Thanku so much sir

[@simrannahar8262]

tysm sir u r amazing

[@SarwanKumar-du9uq]

Thank you🙏

[@somedude9116]

Exuse me sir, at 11:30 should not it be x squared, instead of omega squared????? Maybe i am wrong, but it looks to me like mispelling. What do you think? Very great video it helped me a lot. I have subscribed to your Channel. You love physics.

[@Pavan_Gaonkar_abc]

11:12 you forgot to write root sir..

[@FortheLoveofPhysics]

yes, corrected it later on

[@Pavan_Gaonkar_abc]

@@FortheLoveofPhysics yesh..sorry didn't saw that

[@griffithfimeto3387]

Can you move away so i can take screenshot ?

[@FortheLoveofPhysics]

Next time I will try to incorporate screenshots in the video

[@prashantnautiyal4832]

actually everything is superposition

[@nm-pi9qe]

e(euler's number) real life me exist krta hai

[@debojitsen6250]
