AP Physics C: Simple Harmonic Motion Review (Mechanics)

[@gusdoricko7007]

I don't know why your videos aren't more popular. They're extremely concise and informative. Many a test have been passed thanks to you!

[@FlippingPhysics]

Thank you for your lovely words of encouragement. I also do not understand why my videos are not more popular. Any help you can provide would be lovely. flippingphysics.com/help-out.html

[@truffleshuffle314]

I have been out sick from my physics class, this youtube channel has been a godsend on keeping up with my work. leaving a comment to boost you in the algorithm good sir!

[@FlippingPhysics]

Glad to help you learn!

[@hvy_mtl_drmr9563]

Flipping Physics you are going to get me an A on my physics test tomorrow even though I haven't looked at the material until tonight. It's super concise and informative, keep it up!

[@FlippingPhysics]

I hope the test went well!

[@hvy_mtl_drmr9563]

@@FlippingPhysics I got a solid B which kept my A in the class. Thank you

[@FlippingPhysics]

@@hvy_mtl_drmr9563 You are very welcome. Do realize that all I did was provide you a tool for learning. You used the tool, learned, and earned your grade. Congrats!

[@rachey5148]

Your videos are absolutely my favorite way to study and review. Best concise, understandable, and engaging way to give the information. Oh and that sneeze left me laughing for a while! Bless you haha

[@FlippingPhysics]

That's funny. I forgot I kept that sneeze in there. Glad you enjoyed that human moment.

[@sophiemckay783]

You're saving my physics grade, thank you so much!

[@FlippingPhysics]

You are very welcome. Though I think you are saving your physics grade, not me.

[@pushkarsoni8927]

your students are so brilliant...

[@FlippingPhysics]

We've spent a lot of time together.

[@pushkarsoni8927]

they are awesome. Surely that means its you.

[@FlippingPhysics]

[@pushkarsoni8927]

wow, this much goes in making of a video. you are very hardworking but ur dog seems lazy.

[@FlippingPhysics]

he is.

[@srishtikumar5544]

These videos are absolutely AMAZING!!! I was needing not just answers, but also EXPLANATIONS to the 1998 test and your videos do such a great job of providing those answers. I feel like I have a better conceptual understanding of physics now. Thanks for all of the hard work you put into these videos - believe me, it really pays off. If you could make a couple more test review videos before thest - i.e., for the 2012 released Physics tests/Physics FRQs, that would be EXCELLENT. I'd prefer Physics C, since I'm taking that this year, but the other AP physics work fine too. You are a lifesaver!

[@FlippingPhysics]

You are welcome and thank you for your kind words. With regards to the solutions to the 2012 practice exam. Perhaps someday. It will be a while though, there are so many videos I want to make...

[@srishtikumar5544]

The test solutions would be a great help to all of us who are struggling with physics FRQs. But I understand; thanks so much, and keep it up! I admire your passion for physics - it really shines through your videos.

[@lukenuculaj8389]

Truly a great review on Simple Harmonic Motion. This video along with the others under Mechanics C are helping me to rehash some old but important ideas needed for the AP test. Thank you!!

[@FlippingPhysics]

You are welcome. Glad to help!

[@planeloverpilot4802]

this channel is a gem for jee aspirants who want clear crisp straightforward content .. just the way i want it

[@FlippingPhysics]

Wonderful. Best of luck on the JEE!

[@anishlakkapragada3530]

you have helped me so much. Your videos are affecting thousands of classrooms. thank you so much

[@RDuder]

You deserve so much praise for these awesome videos❤ I imagine your following isn’t as large as it should be because there isn’t a large group of people who seek out ap physics videos on material. Nonetheless you do a great job.

[@FlippingPhysics]

Thanks for the kudos

[@BoZhaoengineering]

very classic. If you study mechanical engineering and engineering mathematics, SHM is a classic model to analyze. Thank you. I love your video, straight to the point style.

[@FlippingPhysics]

Thanks for all your lovely comments!

[@gigijbijbj]

Thank you so much , words cannot describe how greatful I am for your physics videos , keep em coming

[@FlippingPhysics]

I will. I will. Thanks for your kind words.

[@ontheway5792]

I'm an A-level student and I really gained a myriad of benefit from ur videos...Hope to solve more problems...Many thanks broo from Egypt!

[@FlippingPhysics]

That's awesome. Lovely to receive transcontinental thanks!

Hello.. I'm from Saudi Arabia and your videos are so helpful.. Thank you so much for this wonderful videos

[@FlippingPhysics]

You are welcome. So glad to help you out from all the way across the ocean!

[@_madhavx]

6:29 Oh if I said that in my class and the teacher just said "correct" (like you did 7:20 ) , I would have been so mad!! BTW, I love your videos! They are really helpful : )

[@varundixt6292]

There is one and only one problem in your lectures.... That they end... #thankyou

[@FlippingPhysics]

Awesome comment. Thanks!

[@aartisangwan3116]

Looks great. Few things: Substitution of Velocity and Position into KE and PE equation for SHM Period of pendulum with rigid object. I have seen that on AP many times when they are dealing with Torque to derive T.

[@FlippingPhysics]

Yeah, those are good suggestions which I will make sure to cover someday when I get to the point where I am making non-review videos for APC. Someday...

[@arpanpiano]

4:09 LOL I was writing some notes and this sneeze scared the heck out of me!!!

[@carultch]

4:30 We should also clarify that the equation T=2*pi*sqrt(L/g) is only valid if the pendulum can be approximated as a point mass. If the pendulum is not a point mass, it is not as simple as distance from pivot to the center of mass. The physical pendulum is the topic that covers distributed mass pendulums.

[@FlippingPhysics]

Yep. I am currently writing the script for a video about physical pendulums.

[@technicbrasil]

Awesome playlist, I will make sure to watch it tons of times, and do lots of practise exam to get a 5 on the AP test

[@FlippingPhysics]

Please do. And tell all your friends to watch it too...

[@technicbrasil]

I just posted the link to watch the complete review on our class group on facebook

[@FlippingPhysics]

Awesome. Thank you. Good luck on the exam!

[@okbear9427]

Flipping Physics- I know this is an older video but it need some help! How do you, given the Wave Equation, find the solution y(x,t) = Asin(2pi/wavelength)(x+-vt)? Every I look it is just given out of nowhere and I can’t actually find where it comes from and how to calculate it. Your help would be much appreciated! Thank you!

[@edu10th47]

3:41 Sir, why is omega for the spring oscillator equal to sqrt(k/m), shouldn't it be sqrt(m/k)? If not, then how did you convert it to sqrtm/k; I cannot put it on that form. Thank you for your videos.

[@TreesGD]

Angular frequency and angular velocity are the same right?

[@njsynthesis]

I've used this as my primary resource while self-studying this course. Is this what Edison meant by having film replace textbooks?

[@TekkoNet]

around 11:39, you say that acceleration is a maximum at positions #1 and #3, but velocity is 0, so shouldn't acceleration also be 0? btw these videos are super helpful, thanks

[@FlippingPhysics]

Acceleration equals _change_ in velocity over change in time. The velocity may be zero at 1 & 3, however, it is experiencing its maximum _change_ in velocity at those locations.

[@TekkoNet]

@@FlippingPhysics Ahhh, that makes sense, thanks!

[@fasihussaini8554]

Sir, can u confirm whether we have damped oscillation for AP Physics C mechanics ?

[@FlippingPhysics]

Damped oscillation is not in the curriculum, however, i would not be surprised if it came up anyway. They have a tendency to ask questions which go slightly beyond the curriculum to check to see if you truly understand the physics.

[@hellofbsondnsk]

Did this man not cover his GOd DAMN MOUTH while hes sneze?

[@FlippingPhysics]

1) I think goddamn is one word. 2) I think it should be goddamned instead of goddamn. Goddamn is a noun. Goddamned is an adjective. You are using goddamned to describe my mouth, which means it should be an adjective. 3) What is "hes"? 4) Sneeze has three e's. 5) When you are completely alone in a house and you sneeze, do you cover your mouth? 6) I apologize if you get sick due to watching a video where I sneeze.

[@hellofbsondnsk]

Flipping Physics I didn't mean this seriously. Sorry if I made you think that I actually mind if you sneeze in your videos. I actually really appreciate your content and don't mean to insult you at all.

[@FlippingPhysics]

Sarcasm does not come across well in all text situations. No worries. Glad you found my videos useful. I hope the exam went well!
