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.

@FlippingPhysics 5 лет назад

It makes me very happy to know I am helping you learn. I do not have an answer to the paucity of views. Perhaps I need more cats?

We all know this is gonna reach trending when the AP exam season comes around though...

thank u so damn much for all your videos it helps clear things up u put 2 hours for a min of every video!! i dont think i can ever thank u enough for your efforts and time and for my friends bo billy and bobby

@FlippingPhysics 5 лет назад

It is lovely that you consider Billy, Bobby, and Bo your friends. I do too.

Thanks for your effort and time for creatting this educational video. I have actually already graduated in engineering, but your videos are very well made and it helps to keep me my knowledge.

I'm taking Physics C next year and am very intimidated by it, but seeing your channel makes me feel so much better about it

@FlippingPhysics 5 лет назад

Best of luck next year. AP Physics C is a great class.

@@FlippingPhysics I'm doing AP Chemistry this year, and I'll be sure to learn some physics over the summer to prepare myself for the class, and I'll be doing Physics C alongside AP Calculus AB. Isn't most calculus of Physics C based on the Electricity & Magnetism portion? Thanks so much for the response and I look forward to more of your videos

@FlippingPhysics 5 лет назад

@@elliott1781 There is plenty of calculus in the Mechanics portion of AP Physics C. The class can certainly be taken concurrently with AP Calculus AB. In fact, the two classes compliment one another well.

@@FlippingPhysics If I haven't taken previous physics courses, should I just go with AP Physics 1 instead? I'm going to be a senior next year, and I'm looking to major in Mathematics and Physics in college

@@elliott1781 If you major in Mathematics and Physics in college and get a 5 on the AP Physics 1 exam, they will tell you that you need to take calculus based physics. If you get a 5 on the AP Physics C: Mechanics exam, you will test out of 1st semester calculus based physics. In summary: Take AP Physics C: Mechanics. Assuming the class (APC Mechanics) is taught over a full year, you should be fine.
