#APPhysics1 #Review #Waves
You've taught me more in 20 minutes than me teacher has in a week thank you so much!!
+Jess Lewis That makes me both happy and sad.
JUST A FEW HOURS TILL THE TEST!! Good luck guys
F
I am definitely not ready for this tomorrow. Anyways, good luck everyone!
Agreed, good luck to everyone!
Timeless pain
one year later, habits haven’t changed
how'd you do?
Stayed home from my morning classes to watch these in preparation of my AP Exam at noon. Time well spent.
I'm doing the same thing!
+DaisyPeach I'm watching it for a second time
Nate Popodi im doing that rn
same
Same here!
Will you consider doing AP Physics 2? Your videos are helping me out SO much this year Bo!
The ninth in my set of AP Physics 1 review videos. Enjoy! #PhysicsED #flipclass #APPhysics1
Thank you for taking the time make these videos! They have definitely helped me
Great. You are certainly welcome. Perhaps you could "like" the videos in return and let all your friends know?
Good luck tomorrow!!
It is so nice of you doing these videos. They are soooo helpful!!
+Shurui Yang You are welcome. I am glad you find them soooo helpful!!
just wanted to thank you alot for this review, you helped clear up a ton for me. keep it up! :)
Matt Brink You are welcome. I am very glad to have been able to help you understand more physics and don't worry, i'll keep making videos. :)
These are really awesome! Thank you so much!
Omg, you saved my life on 2019 phy1 exam! There was no way I could have known the knowledge in 13:55 other than watching your video! That was a whole frq! (2019 frq5 a,c) thank you! Thank you! Thank you!
IM NOT GONNA FAIL MY QUIZ TOMORROW TYSM LY
thanks for the Doppler review
thank you 👍
i like the idea that two things can't be in the same place at the same time, but the energy from a disturbance in the things can
I like how you're all wearing each other's socks.
.thank you for explaining standing waves! Really helped me
MopTopRock Great! Glad to be able to help you learn!
I really appreciate the videos man.
+Sanchit Singh You are certainly welcome.
this helped A LOT!! Thank you very much!
윤원준 You are welcome. Thanks for learning!
So helpful 😭 I have a test tomorrow about waves and watching your video cleared up some of the misunderstood information I had 👍🏼
+Mariya Purana (Mari-chan) Glad to see your 😭 turned into a 👍🏼!
Hehehe! I got a 96 on my test! Thank you so much for your videos. I also use them to remember the previous lessons. Especially Work and Rotational Kinematics...
Thanks for making these reviews!
You are welcome. Good luck today!
Flipping Physics Thanks!
If I binge watch your videos this week, I think I am going to do well on the physics 1 exam
Good luck on the exam!
im about to die on tuesday rip
You and me both.
I feel you
come on guys we can get this dub. good luck in a few hours.
F
we will go down together
Your videos are amazing!
+supers970 Thank you. Good luck today!
UPDATE: Test went better than I expected. Expecting a 4. :)
Have the mock tom..... Only reason I might not fail is bc of you :)
Finished the video grind!
please can you make ap physics 2 reviews
Thank you very much!
What is a fun website you may know of that makes playing with beats fun?
You are the best! Thank you!
You are welcome!
Nice coordination at 18:12 (yes i am still studying 2.5 hours before the exam…)
+Flipping Physics The test turned out ok! It was super difficult, but at least I understood the difficulty of it. Thanks for all the help
i love these videos! you explain things very well and also write down the very important things for us visual learners. i also enjoy your classroom theme with bo billy and bobby. its very interactive and informative. thanks for your hard work. also, Billy is wearing a black sock, not the corresponding orange one. XD
That's great. I am so glad you were able to learn with me. Thanks for the lovely comment. Perhaps you could "like" the videos?
Regardless, enjoy the exam today!
Sound section review?
For the AP Physics 1 exam, do we need to know about indexes of refraction and Snell's law?
No, optics are not a part of AP Physics 1. See: flippingphysics.com/ap-physics-1-review.html
Should I sign up for ap physics 1 when I haven't taken a physics class before?
Absolutely. AP Physics 1 is a great first physics class. If you want to know more about the various AP Physics classes, go here: www.flippingphysics.com/which-ap-physics-course.html
2018?
*So underrated!*
Mr.P, what happens to the wave while in destructive interference? Shouldn't the waves ,after cancelling out one another , just stop ? I mean, how can they still propagate in their resp. directions unaffected? If this true, what is the significance of destructive/constructive interference ?
BTW, thanks a ton for making these videos. They help us a lot.:)
I think you are confusing waves with physical objects. A wave is not a physical object, it is a disturbance of a medium. Two waves will pass right through one another, unlike physical objects.
isnt this not in ap physics 1 curriculum anymore?
do we have to memorize the formulas used in the video for the AP test?
Most of these equations should be in the formula sheet that they give you but at the same time they'll be at there basic forms....anything that involves converting would not be on the sheet
Very Good Friend;)
Watching this while sitting outside the exam center
I hope it went well!
What is the picture in the top left
+Isaac Escobar This is essentially my office and those are pictures on my desk. Upper left is my daughter Geneve walking with her cousin Graham. Upper right is my wife and two daughters.
You should include some practice problems in future videos
+Aishvarya Pathange I put practice problems here: flippingphysics.com/algebra.html and I am constantly working to add more.
Why is an electromagnetic wave called a wave since a wave by definition is a disturbance in a medium, and we know electromagnetic waves don't require a medium? Or is it just that they need a medium to form but not propagate?
What a great question. Honestly, I don't really know the answer to your question. Electromagnetic waves are the only wave we know of which does not need a medium to propagate. Therefore, what is being "disturbed" by the wave?
I agree. This is a great question. Although definitions of waves often include reference to a disturbance in a medium, a broader definition is that any function of space and time that is a solution to the wave equation is a wave. EM radiation meets that definition since as functions of space and time, the electric and magnetic fields that constitute EM waves are indeed solutions to the wave equation.
Technical details: A wave equation for E and for B can also be derived from Maxwell's equations. Those derived wave equations predict that E & B both travel at the speed of light, and relate that measurable speed to other measurable quantities, namely the electrical permittivity and magnetic permeability of the medium. You could consider the medium that is disturbed by an EM wave to be a complex vector field that has no mass, but has a particular stiffness (permittivity) and inertia (permeability). There is some truth to an analogy of space-time being somewhat like a massless drum head whose tightness or stiffness is characterized by its permittivity and whose sluggishness or inertia is characterized by its permeability. The struggle between stiffness and inertia is wave allows any vibration or wave to occur.
Note that the human-created wave-equation description of waves is, like any other model in physics, a model, created by humans. Nature need not follow the model just because we created the idea of wave. However, the wave model works very well for a large number of physical phenomena and allows us to understand and learn more about those phenomena. In the case of light, it does indeed sometimes fail to behave in an entirely wave like manner, at least, it also exhibits characteristics that fit another model we have created: the particle model.
where can i find some more viedios?

www.flippingphysics.com/algebra.html
please make more videos
Currently doing so.
Hi Mr. P, what does constructive interference mean?
+Erica Hu I explain that in this video: ruclips.net/video/4uFhzrLENBs/видео.html
BOjangles!
You the best
tanks.
you just saved my grade!
+Vintage Gamer dude Awesome!
whats the app?
+Luis Sanchez People really don't read the descriptions of RUclips videos. Do you not realize people put information like this there?
I watched many of ur videos........i m a big fan of u.........i just want to know......what is this AP Physics......
Thank u...
:)
+Fun Living (Satvik) AP Physics 1 is a curriculum developed by the CollegeBoard. It's an internationally recognized curriculum with a test in May. There is also AP Physics 1, AP Physics C: Mechanics and AP Physics C: Electricity and Magnetism. Thanks for being a fan!

+Flipping Physics Thanks for the knowledge
When you said "so it sounds like this" and then went nerommmm for all three I actually laughed out loud
Great! FYI: Your comment made me chuckle. Good luck today!
Thank you so much. Just by the way I'm going to recommend your videos to my science teacher because they are really really helpful.
I noticed the Audio Tool link is no longer correct when you click it, it should be www.performanceaudio.com/apps
Also, if you are on a laptop, here's a website I found to create tones: www.szynalski.com/tone-generator/
And lastly, if you use android devices, I found this app works well, called "Frequency Generator".
Thank you! I have updated the link and added your other suggestions as well.
Nyeerrww
This was very helpful, and thank you! But... why do all of the students have mismatching socks?
The implication here is that one's socks must match. Why do you feel this way?
God tier
Who's watching this one hour before the test??
Me lmao
I love u :)
+Habibiii Thanks for the love. Love you too.
I'm a senior in high school and we study this in Morocco . Do you guys study this in college or high school ?
In the United States physics is split about 50/50 between High School and College.
That's my best guest.
maria countrow Most physics in high school is algebra based, whereas college physics tends to be calculus based.
Niloy well AP physics curriculum is Algebra based and my school has been in a few top 100 lists (Newsweek/Washington Post), unless it's the International Academy or IB classes or something.
like the socks
3 hours out, good luck guys
out standing explanation. but it is too fast for AP in my point of view.
It is a review, therefore, it is meant to be fast.
2019 day b4 gang?
Mehul Ghosal represent
FUUCCKKJCSSFH 12 HOURS AWAY 😭😭😭
By far my least favorite topic in AP Physics 1...Good luck everyone!
Do you like music? This topic is essentially the physics of music.
T-1HOUR
RIP users who used headphones
+Eber Amezcua Sorry about that. Could you be more clear as to where the offensive sound is? I actually tested this video with headphones before I posted it because I was concerned about this.
Flipping Physics When you played the tones on the phones, I guess I just had the volume too high lol. It's a good video though, it helped a lot.
+Flipping Physics Frankly, I thought the sound was very helpful in holding my attention. Sound level = Good. #WontFailMyExamTomorrow
the first guy talks in the most annoying voice please stop
