Equation for simple harmonic oscillators | Physics | Khan Academy

In this video David explains the equation that represents the motion of a simple harmonic oscillator and solves an example problem. Created by David SantoPietro.

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

This guy is incredibly good at explaining physics concepts. This is the best SHM video I've found on YouTube.

Holy cow, I'm learning this in Vietnam as a Highschool 12th grader, it's confusing and giving me a hard time, this actually just answered all of my questions. And give me answer for question I didn't know I need! Thank you

[rouxadrien]

awesome explanation, you just saved a french first year mecanical engineering student

[richphero]

I do not know how I didn't see this as just a high school senior-level math problem... literally learned this in trig... thank you!

[avp]

Wonderful explanation. Hit the nail on exactly what I was struggling with. Thanks for your help, David!

[maikkempen]

The lessons on Khan Academy are very useful and clear! Keep up the good work!

As a jee aspirant and a 12th grader i can't express how amazing this video is. Made me learn the formula just by simple logic 👍🏻📚

[bluefoxf]

Great explanation! Thank you! This function is beautiful when you completly realize how it works!

[JP-xmqf]

Thank you very much David!. I got confused on the "re-setting part of the equation" but thanks to you it was much clearer!.

7:33, literally answered the exact question I needed, how to get angular velocity out of velocity.

9:04 In my humble opinion, using 2pi/2 could be simply illustrated in terms of horizontal dilation i.e 2pi*λ=T so that λ=T/2pi, and hence 1/λ=2pi/T.

Perfect explanation than any video on youtube till now

[christianmendez]

this vid on harmonics is the one I understand the most. thanks a lot!

I know this is from three years ago, but you can express the graph that you gave as an example in terms of sine, assuming you shifted the whole graph to the right 1 unit (sec) so it would be like : 3sin ( (2*PI/4) (t-1) )

[beenamachhami]

couldn't be explained better. thanks.

[Z-eng]

If not for my large number of saved liked videos I would've given a like to almost every single video you make 😂, thanks allot really you saved me

[gokulram]

Thanks a lot ! i understood in the first shot ! much easier to understand than my text ! thx again !

[galtrost]

You are a G my dude. Saved me so much time and energy.

[hieunguyen]

Thank you for simplifying such a chronic problems of mine❤❤

[MrNurseinTExas]

this is what I needed for a starfield simulation elliptical-orbit I am working on for my game... thanks!
