AP Physics C: Kinematics Review (Mechanics)

[@weasellikesnoodles]

5 UAM variables 4 UAM equations If you know 3 UAM variables... You can find the other 2 variables Which leaves you with *1 HAPPY PHYSICS STUDENT* My life motto right now.

[@FlippingPhysics]

I like your life motto.

[@albertod4]

There's actually a fifth UAM equation - xf = xi + vf t - 1/2 a t^2

I want to like this comment but that wouldn't be *Nice*

[@Silverhawk676]

Due to corona, this has become my classroom. Thank you.

It would be lovely if the person who translated the captions of this video to Spanish could contact me. I would enjoy being able to say "Thank You!" and give them credit.

Once i was so pessimistic ! I probably had no idea what to do and then i started seeing your videos ! God knows how much i have changed 😍 i have started learning with reasoning rather than taking it as a scientific fact ! Thank you flipping phyics !! Thank you !! You are the best teacher i found on youtube channel !! Keep progressing ! You have the potentiality of changing an abecederian to a genuis one !!!! And to tell you the truth , i like your voice and the way of your teaching ! Perhaps i have been watching all of your youtube videos just to listen your voice and gain free knowledge !!! I really love your videos !! I m literally going to be changed from "belieber" to "flipper" thanks !!!!!!!!!!!! Not only from my side but from the entire world who have changed their status of learning !!!! Thank you !!!!!!!!!! Thank you !!!! I probably have already written a lot but its nothing infront of your valueable teaching !!!!!!!!!!!!!!!!!!!!!!! 😊

[@FlippingPhysics]

What an awesome comment to wake up to this morning. Thank you for your kindness and than you for teaching me a word. I had never heard of an "abecedarian" before. Now I will be sure to use it whenever I can.

[@camilamendes5902]

Flipping Physics i cant believe i could help a person learn a word who is probably helping the entire world to learn paragraphic form of understandable science !! Can a god neglect the fact that he is immortal and the best ? , can a child neglect the fact that he is naughty ? No !! Right ? So you are the most sophisticated youtube teacher who knows how a student studies and who also knows how they can be improved !! You cant neglect the fact that you are the 100 times renovated gift of god !!! You are the best ! Despite of being proud and cuddling over yourself , you are probably helping the world to learn something ! " you haven't been giving fish to your students but infact you have been teaching them the technique of fishing !! This is what a good teacher does !! So you dont have to say thanks !! 😌

[@michaellozano5796]

I love your videos. You were the reason I passed my AP Physics 1 Exam with a 4, 8 years ago. Now I have a minor in Physics and I am preparing to tutor my 4th student by watching these videos again. Thank you

[@FlippingPhysics]

This is awesome. Thanks for letting me know!

[@jmp071899]

Thanks so much for the review. I self-studied AP Physics C: Mech this year, so these videos are awesome review tools for May.

[@FlippingPhysics]

You are welcome. Hopefully they will all be done in time... (Power has been out for 48 hours which has made things challenging)

[@stevediben7900]

I'm in college introductory physics and have loved utilizing your videos throughout the semester. Thank you and keep up the awesome work! I don't know to what extent AP Physics courses touch on rotational kinematics/dynamics, but it would be awesome if you made more videos on the topic.

[@FlippingPhysics]

You are welcome! With regards to rotational kinematics/dynamics, you can see exactly what I am planning to film, along with lecture notes, in the next few weeks here: flippingphysics.com/quality-control.html

[@John-lf3xf]

I remember being here exactly 1 year ago at the beginning of AP Physics 1... long way

[@ineshtickoo2530]

It's so amazing that a foreigner knows and cares about JEE/NEET and esp for a person like me who's prepping for JEE as well as AP.

[@eddyhernandez8055]

thank you for the 5, your videos clarify the subject SO WELL

[@sarthakkalekale4634]

I believe in you sir you are honorable and will remain ever in in my mind you are so respectful personality and passionate and hardworking person

[@FlippingPhysics]

Thank you for your kind words.

[@dianeyev7536]

I just found my new classroom ♡ Any thoughts about the new AP Physics C Mechanics exam format?

[@FlippingPhysics]

It was definitely time!!

[@shaunwu3609]

Great review. Saved me a bunch of time flipping in the textbooks!

[@FlippingPhysics]

You are welcome!

[@aartisangwan3116]

I looked at it and did not find any loop holes or mistakes. Will look over again for unit vector problem.

[@OwnedSoda13BBH]

Is this a good series to learn Physics C?

[@MJ-hm2sn]

awesome

[@RickTrajan]

I have a very odd question, let's say a vehicle is falling from a cliff - let's not bother about it crashing to the earth and make the downward acceleration to just a constant speed(if it would be a big problem at least). how would accelerating and decelerating after how the vehicle maneuver up in the air - at least for a mid engine rear wheel drive, and if you like you can add an awd. thanks? I think accelerating will make the moving wheels plummet faster but way more when you brake. it was just a silly discussion online of a video game.

[@iangolsby8471]

It's been 3 years so sorry for late response haha. Vehicles rely on friction between the tires and ground to maneuver. When a vehicle is in freefall, regardless of its engine and drivetrain configurations, there is nothing for the wheels to turn against. The wheels can rotate, but they will not change the falling of the vehicle. Because of conservation of angular momentum, the spinning of the wheels will lead to a slight amount of spinning in the opposite direction for the car. (Technically, this will alter the drag profile of the car and change its fall, but we're ignoring air resistance). Any game that lets you move in the air is either lying (Minecraft lets you move normally), not actually moving you (gyroscopes can let you rotate but no translation), or the creator doesn't understand physics.

[@shangzhu8738]

I love your videos so much. Do you have ones for E&M?

[@anyay.4010]

thanks king this was so helpful

[@FlippingPhysics]

You are welcome

[@wonjaesuh5839]

THANK YOU MR. P

[@MackoWackoGaming]

Anyone taking Physics C: Mech this year?

[@MJ-hm2sn]

do not we take + 9.81 for acceleration when object is falling on the earth ( towards centre of earth)?

[@FlippingPhysics]

Please watch: www.flippingphysics.com/common-free-fall-pitfalls.html

[@yours1ana]

u can define the positive and negative directions. she assumed up is positive so the y acceleration is just gravity which is -9.81m/s2

[@spidy_zihi]

Hi thanks for this!

[@ptyptypty3]

Okay, just starting to view the Video..... I'll post my comments after having watched it.. :) Stay Tuned.. Don't touch that dial.....

[@soccernicholas6]

Did you make one of these reviews for the E&M test as well?

[@FlippingPhysics]

No, sorry. I did not.

[@soccernicholas6]

Flipping Physics that's okay! I remember a lot more of e&m because it was this semester. that's okay! thanks for making these!!

[@saffrown]

Flipping Physics can you please make some for E&M?

[@CYC10N3_Gaming]

How do you find the one UAM variable with 2?

[@FlippingPhysics]

You can't. If you have 3 of the UAM variables, you can figure out the other 2.

[@CYC10N3_Gaming]

@@FlippingPhysics ok, but how if you only have 2 variables,

[@FlippingPhysics]

If you only have 2 out of the 5 variables, you cannot figure out any of the other 3.

[@CYC10N3_Gaming]

@@FlippingPhysics sorry, I'm asking how do you find the other 2 UAM variables with 3 known

[@technicbrasil]

Will you post review videos for all topics before the day of the exam ?? I will be taking the exam, even I have being a solid 95%-97% I would really like to be able to review using your videos, and yes I know you have a complete review for all the topics covered in the APC test however those are pretty much all the equations we need to know not the physics we need to know

[@FlippingPhysics]

I am planning to finish all the review videos before the day of the exam. You can see all the lecture notes, scripts and current progress @ flippingphysics.com/quality-control.html

[@aartisangwan3116]

Thanks again.. you are awesome ...

[@FlippingPhysics]

You are welcome and thank you.

[@jurgengotz3535]

the density of krypton is 3,75 g/l , its a gas

[@firmannugraha8236]

wait are AP Physics C doesnt include speed?

[@FlippingPhysics]

Speed is in definitely covered in AP Physics C: Mechanics. What led you to believe it is not?

[@firmannugraha8236]

@@FlippingPhysics no i think it is not included because when you explain velocity you just go through to free fall 😁😅 maybe because to make the video more concise and time friendly eh

[@firmannugraha8236]

@@FlippingPhysics yeah finally THANKS FOR MAKING THESE KIND OF VIDEO! really help with my physics mid term. I am already seein the AP Physics 1, and i am seeing speed being explained by yours truly. so whats actually the difference in each same theme of lesson but different section of AP? Like, whats the difference in this mechanics video and the AP Physics 1 mechanics video?

[@FlippingPhysics]

Yes. This is a review video, so I probably did not cover speed explicitly. However, speed is built in to many of the concepts covered in AP Physics C: mechanics.

[@FlippingPhysics]

I am not quite sure what your question is, however, I will do my best. AP Physics 1 and AP Physics C: Mechanics cover about 75% the same topics, however, AP Physics C: Mechanics includes calculus. This means AP Physics C: Mechanics is to delve more deeply in to the topics than AP Physics 1. I hope that helps!

3.75 g/cm^3 = 3750 kg/m^3. yout calculation is right, the result not.

[@FlippingPhysics]

Did you actually watch the whole calculation? At 1:08 Bo explains why it is wrong and the point is that the mistake which is made is a very common mistake students make.

[@camilamendes5902]

Flipping Physics absolutely !! This is the reason i love watching your videos !!!
