Flipping Physics Blog

I always enjoy creating my Flipping Physics Trailer . It involves taking a small slice of almost every video I made during the past year. It’s always fun to look back on what I did during the year

Impulse = Area

Say hello to Zion and Mikey! I am currently visiting relatives in Maryland and, while finding my seat for the Spiderverse movie, I met two Flipping Physics students of mine. So cool!

Are you, or is someone you know, studying AP Physics 1 this year?

Don't know what to get that awesome physics teacher who wrote your letter of recommendation? Have some students you want to reward for excelling in physics? Do not worry! I have a gift idea for you. Flipping Physics Swag! For the rest of today it is all 25% off! Use the code GET25TODAY.

Sometimes I share positive comments I receive for my Flipping Physics videos. Today I share. Here are comments I have received this month: - "You are the reason I'm passing my college physics course. I've taken pages of notes on your videos and I wish I would've watched you sooner back when I was struggling with projectile motion a couple months ago. How do you not have tens of thousands of views? You deserve so much love and respect." codyriceandothers - "Probably the best moment of inertia explanation I’ve seen and I finally understand it. So grateful for people like you" campinglamp - "you are  a m a z i n g. i wish i had you as a teacher at school. anyway... i suppose i can say that you are my teacher now, and a better one than any of those that i ever had! i am so glad i have found your channel, i want to be able to one day to say to myself that i've learned everything you had to teach in all of your videos, because i really want to s

New Video ! You gotta start simple, before the physics gets more difficult.

Dropping Dictionaries Doesn’t Defy Gravity, Duh!

Thank you to all of the attendees to my various presentations over the last two days! I really enjoyed presenting about Flipped and Gameful Learning. But I especially enjoyed spending time training physics teachers! It was really cool to get to learn from you as we learned together. 😀

Heading to Birmingham, AL to present at the A+ College Ready 2 Day Science Fall Conference. That’s right, I’ll be teaching physics teachers how to teach AP Physics 1! 😇 What do you think the chances are that my bag was manually searched?

Have you ever struggled to describe Rotational Inertia to your students? Even worse, have you ever struggled to understand Rotational Inertia yourself. (I know I have. 😇) Did you know Rotational Inertia is the same as Moment of Inertia? Yeah, I’m with you there. I did not know the name had been changed until recently. However, I do think Rotational Inertia is a more logical phrase than Moment of Inertia. Well, if you would like some help with the concept of Rotational Inertia, then I highly suggest the Rotational Inertia Demonstrator from Arbor Scientific because it is an easy way to demonstrate the concept of rotational inertia. The demonstrator is composed of three pulleys of different sizes all centered around the same axle. Attached to the pulleys are four spokes on which four masses can be placed. The distance from the axle, or axis of rotation, of the four masses on the spokes can be adjusted. In order to understand rotational inertia, we should first review the equati

My family pushes on a door so you can learn about net torque.

Don’t be too cool for the right hand rule .

A wrench is a simple way to learn about  torque .

Through natural, slow attrition, the number of people who are currently on my Quality Control Team is a bit low. So, if you would enjoy having influence over the creating of Flipping Physics videos, please visit . Right now there are FIVE scripts just waiting for you to read them and leave helpful comments on the Google Doc! I'd like to film by Monday. So it would be lovely if you could do so soon. Thanks!

Yep, it's time to introduce the concept of torque !

Last Sunday I posted this video and received lots of wonderful words of encouragement and only one person who said they would do what I have requested. Understand that I appreciate your words of thanks, however, what I really need right now is for people to share their words of thanks via video. The reason I would really like this is so I can create a montage of y’all saying great things about Flipping Physics. This will encourage other people to view the videos and I will, hopefully, less often hear “I wish I had found Flipping Physics earlier!” I know there are many of you who have learned copiously from my videos. All I am asking in return is that you film yourself saying thanks and send that in to me. Please. I could really use your help. Thanks. - mr.p #APPhysics1 #APPhysicsC #AAPT #PhysicsED

Perhaps imitation is the sincerest form of flattery. If so, this is a lovely piece of flattery. Here is a video created by some AP Physics 1 students last year. Note the three characters and socks. I make a special appearance at about the 8 minute and 10 second mark. Thanks for sharing Kaitlyn!

Would you like to share your story about how Flipping Physics has helped you or your students learn?

If there are any students who are using my AP Physics C: Mechanics in-class lecture videos to self-study for the AP exam, it would be lovely if you could contact me at jon at flippingphysics dot com. I have a simple video organizational project you could help me with while you are going through my videos. It would be much appreciated. Thanks. With regards to these pictures. I was pleasantly surprised to realize a GoPro Hero taped to the ceiling will actually stay there and produce useful results . Who knew?

Please do not memorize moments of inertia equations,  instead understand how to estimate their relative values.

A basic question to help with understanding of Moment of Inertia or Rotational Inertia.

Now we actually calculate moment of inertia and rotational kinetic energy .

Crowdsourcing English transcriptions for my videos is going so well, I thought I would try the same thing with EDpuzzle Lessons. If you are a teacher who uses EDpuzzle Lessons for my videos, you could help me out by making them for my videos which do not currently have them. This will allow me more time to make the videos. Everybody wins!! So, if you would like to help, please email me at jon at flippingphysics dot com from the email you would like me to use for sharing a Google Sheet with you. The Google Sheet will keep track of all of your fine work. That's the basic idea. Wish me luck!! - mr.p

And now, Moment of Inertia ! Oh, and Rotational Kinetic Energy, because you shouldn’t define Moment of Inertia without Rotational Kinetic Energy.

A student from Egypt, Youssef Nasr, has been transcribing all of my Flipping Physics videos since last November. In total, he has transcribed 28 videos and 29,561 words. Thank You Youssef!! Unfortunately, he is finding he has less free time to volunteer to help me out and has fallen behind. So, I am looking for other lovely souls to volunteer their time to convert my scripts to English subtitles. If you are interested in helping the world learn physics, please let me know. Thanks.   - mr.p p.s. Looks great on college transcripts!!

Thank you to everybody who contributed shares, likes, etc. of my previous video. Your help netted a fivefold increase in views and likes relative to my recent videos, which is awesome. In theory this should help long term because the YouTube Algorithm severely favors videos which perform well shortly after being published. And now the Introductory Center of Mass video. Why now? I was waiting till I could get my wakeboarding video… 

Due to the highly educational nature of my videos, it is unlikely any of my videos will ever go viral. However, it would be nice to give one of my videos a little “push”. Let’s try that with my most recent “ canoe ” video. It would be great if you could like and/or share this post, and watch and like the video on YouTube. I have never tried this before and am curious how effective it will be. Thank you for your help and wish me luck! -mr.p
