This has to be one of the absolute BEST videos I have ever seen on resonance for introductory physics. Especially after studying acoustics in my undergrad where I worked on developing a national outreach program for the acoustical society of america, flipping my classroom as a teacher and researching many videos, and now being a graduate physics student studying acoustics again. Well done! I especially love the swing set examples of not resonance and the resonance of the body helping to act as an antenna amplifying the signal of your key fob. I've been asked that question so many times.
thank you for the substantial amount of hours you must've put into these videos. they are very knowledgeable and they help clarify everything my teacher at school teaches because her handwriting is illegible.
hi sir I am from India and I love your videos ,your way of demonstrating experiments is just so cool and interesting,it helps me learning the concept very easily , also I don't go to tuitions and I study from CZcams watching videos of you and other educational channel. Thnx sir and love from India😚. May God Bless You. Thnx once again.
What happens with students is they are dumped with loads of theories. We can't digest all the theories without any practical knowledge. Grateful to you for these videos. Really love it.
I was intrigued with this video's plot, seeing his three alter ego students being self-motivated to come up with their own calculation to explore his demonstration.
It's the chord known as C-suspended-4th, with the music notes C, F, and G (Do, Fa, & So). Middle C is very close to 256 Hz, and the corresponding F and G in the same octave on the same scale, would be 342 Hz and 384 Hz respectively. It is very common for a 1:1.5 music note interval, like that of C and G, to form a chord, the interval known as a perfect fifth, because of how well the waveforms fit together. Actual middle C is a little higher than 256 Hz, because A is used as the note that is specified as a rational number of Hertz (440 Hz).
Your videos are fabulous. I am from India. I didn't know P of physics. Now one of the reason is your videos because of which I m able to create interest in Physics Physics is really damn interesting.
See? That's why I'm a Patreon supporter. Sublime as always. Whilst watching I was wondering whether Billy, Bobby, and Bo are based on actual students ...
Thanks. When making the video I also discovered that my key fob is also slightly directional. When you get to the edge of the distance where it works, try turning the key fob and see if that makes a difference as well.
Consider the basic equation of motion for simple harmonic motion of a mass on a spring. m*a = -k*x Which can be rearranged for: m*a + k*x = 0 Replace a with d^2 x/dt^2, to make the simplest second order differential equation you'll solve: m*d^2 x/dt^2 + k*x = 0 This is the equation that governs its natural vibration motion, if you start it at an initial displacement x0, and initial velocity v0, and then let it vibrate freely. The solution will take the form of x(t) = A*sin(w*t + phi), where w=sqrt(k/m) which determines the frequency, and A and phi are constants that you can calculate from initial conditions x0 and v0. This is how it will move as a function of time from the initial conditions onward. Now, what if, instead of just giving it an initial condition when it starts vibrating, we apply a forcing function that continues throughout its motion? This is what resonance is. The response of a system that vibrates, to a stimulus from the outside environment at its natural frequency. Suppose we apply a forcing function given by F(t) = B*sin(c*t), where B and c are constants. This could represent a vibration taking place on a moving floor, responding to a background sound, or a human hand shaking it. Maybe the mass is a car, and the spring is the suspension, and the forcing function is a bumpy road the wheels experience. Now the equation of motion is: m*d^2 x/dt^2 + k*x = B*sin(c*t) When c=w, you end up with a particularly interesting result to this equation. The amplitude of the sine wave solution will continuously grow as a function of time. This is resonance.
How in the world does someone put out so much high-effort content??? Fantastic videos!
Time, patience, and love. Thanks for caring!
Exactly! Your videos deserves so much more. They're best on CZcams for high school physics

Wow. That is some very high praise. Thank you very, very much!
I never knew of it...it is insanely amazing sir
This makes me 😃
5:57 SQUIRREL!!! (thank you for making videos, they are fun to watch and very informative)
Thank you! This is amazing and helpful❤❤
Thanks!
thank you for the substantial amount of hours you must've put into these videos. they are very knowledgeable and they help clarify everything my teacher at school teaches because her handwriting is illegible.
You are very welcome. I am sorry about your teacher's handwriting; that must be difficult.
Among the best tutor in physics!

May God Bless You. Thnx once again.
It makes me very happy to know I can help you learn physics. Best of luck to you in your studies!

3:38 the 3 frequencies you chose for that tuning fork demo was really pleasing..it sounds like some meditation 🧘♂️ music

Great respect for you people, keep helping🙏
Do you still teach students at a high school? Also I’m in love with your videos.
I do still teach high school physics, however, I teach part-time in order to have the time to make these videos. Glad you enjoy them!
Flipping Physics I’m glad you have the time to make these videos because they allow me to pass making a C to an A
Congrats on improving your grade! You must be proud of your hard work to do so.
Really great episode! The last demo was especially impressive! The physics works!!!
Why yes, it does!
Nicely explained
Thank you
I came to know many things
I'm a video producer, and Im also in a college level physics class. This is so impressive on both fronts!
Thanks. I am quite proud of this video. Enjoy learning physics!
Your videos are fabulous.

Thanks. I love this video. I've got to get back to doing more videos like this one.
Very, very good. Thanks!!
You are very, very welcome!!
but the radio wave is the kind of electromagnetic wave, can it goes through your body?
Damn!!! This is amazing!!!
Thank you very much!
Wow man, you are amazing... Uhhhh... Maybe not as amazing as physics, but yeah, you are amazing...
Thanks for the kudos!
I guess it is me who should say "Thank you" for such amazing videos. Nevertheless, you are welcome and, of course, thank you!
I got 5% thanks
Could you use an Ahnk as a tuning fork
Fantastic video. Absolutely loved it! The tool you had at the end to prove that you were correct, showing the frequency, what was that tool?
Glad it was helpful!
That is a screen recording of Adobe Audition.
Another AMAZING video, thank you so much! And the key fob thing? How cool is that? I'm unlocking my car like that every time now.
Thanks. When making the video I also discovered that my key fob is also slightly directional. When you get to the edge of the distance where it works, try turning the key fob and see if that makes a difference as well.
7:16 how do you know its a standing wave?
What exactly is resonance? Vibration?standing wave? Up and down?
Consider the basic equation of motion for simple harmonic motion of a mass on a spring.
m*a = -k*x
Which can be rearranged for:
m*a + k*x = 0
Replace a with d^2 x/dt^2, to make the simplest second order differential equation you'll solve:
m*d^2 x/dt^2 + k*x = 0
This is the equation that governs its natural vibration motion, if you start it at an initial displacement x0, and initial velocity v0, and then let it vibrate freely. The solution will take the form of x(t) = A*sin(w*t + phi), where w=sqrt(k/m) which determines the frequency, and A and phi are constants that you can calculate from initial conditions x0 and v0. This is how it will move as a function of time from the initial conditions onward.
Now, what if, instead of just giving it an initial condition when it starts vibrating, we apply a forcing function that continues throughout its motion? This is what resonance is. The response of a system that vibrates, to a stimulus from the outside environment at its natural frequency.
Suppose we apply a forcing function given by F(t) = B*sin(c*t), where B and c are constants. This could represent a vibration taking place on a moving floor, responding to a background sound, or a human hand shaking it. Maybe the mass is a car, and the spring is the suspension, and the forcing function is a bumpy road the wheels experience.
Now the equation of motion is:
m*d^2 x/dt^2 + k*x = B*sin(c*t)
When c=w, you end up with a particularly interesting result to this equation. The amplitude of the sine wave solution will continuously grow as a function of time. This is resonance.

How do these all standing waves look like?
