- Today Flammable Maths and I send each other some maths/physics memes to settle the score on who's the biggest loser, and he pulls out all the stops to convince us it's him. If one of us laughs at the other persons meme, we then have to solve a physics problem.
Check out Flammable Maths part: You Laugh You Math:

Andrew : *needs random number generator*
Also Andrew : *imports numpy and sympy for no reason at all*
A true physicist indeed ! 👍
I would like to thank my mom and dad for this achievement . I have worked really hard for this....😍
500+ likes. Yikes 😬
6:48 is the most beautiful equation i have ever seen. The beauty of first assuming pi equals 3, just to assume pi is 3.3 one calculation later is just incredibly hot
Well pi squared does equal g
Idk why but im laughing so fucking much
G/Pi=G/3=3.3=Pi
Lmao
@@RhynoBytes857no...
Andrew can neither maths nor phys confirmed! :^)

you gotta stop with anime
and buy disney instead
He can't even laugh
5:48 her brother? So Andrew's grandparents named their kids Joe and mom?
Absolute legends
There are levels to this, and Jens exceeds all of them
10:50 should have just been like "well, assuming the equivalence principle, the equivalence principle is true"
For question 6, both of you are correct, you do have to accept that inertial and gravitational masses are equivalent, but past then you have to do the calculation as Jens did and you find that to lowest order the result is independent of the small mass
Thx Thomas! =)
Is it not that (for the same mass) a smaller object has a smaller surface area thus less air resistance? If there is no air resistance then t_fall is independent of the mass of the object whereas t_fall depends on the mass when there is significant air resistance. Not exactly a mathematical answer though
@@interpird350 I believe air resistance was neglected for the sake of a quick calculation, but in general a true calculation of the fall time will involve both masses. The only reason we normally treat the bodies completely independently and don't use reduced mass μ is because we can treat one of the masses as static. For a full calculation you should include air resistance too, but for that we would need to know more than just mass, you can have small heavy objects and large light objects, so the mass would be one of multiple input parameters.
@@tommc1425 Yes now I see the point. Thanks for explaining
Thanks for the clarification - I only knew about the explanation that Flammy described. I’m still a bit confused about Andrew’s, but I’m going to look it up and your description made it a bit clearer. (I only took two semesters of algebra-based physics back in the 80s)
Man, that infinite series one was so easy, I solved it in 10^-4 seconds, and I'm -1 by the way.
lol
damn it took you that long? i solved it in (insert a hyperreal number) femtoseconds, I'm -omega btw
andrew's one of those people who doesn't name his jupyter notebooks, so he's basically like all people
Arguably the funniest questions yet, out of the you laugh you ... cinematic universe
The "how much force from Jens anus" was a real cliffhanger and left me excited for further seasons of this format!
Math problems phrased as stories: John goes to the gas station and buys 453 watermelons. At dinner, he eats 257 of them. How many watermelons does John have left?
Physics problems phrased as stories:
Ah yes very easy maths that I can definitely do.
1:43 the computer in the back 😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂
finally someone noticed XD
I’m no physics major, and haven’t done mechanics in a while. But I’m damn certain that last answer is 69N.
-electrical engineer
I think papa flammy was high when he wrote all these questions 😂😂😂😂
“this is how Italian people sleep” was the funniest for me
These should be on the physics GRE
I'd still find a way to bomb it
This is the most nerdy video ever, i love it 😂😂
you laugh you unstable periodic orbits
ranging from lorenz, rossler, three body problem, forced duffing, etc.
Do something related to relativistic mechanics! Also, ❤️ to both those people in this video!
These question scenarios are fucking hurting my sides 😂
Awesome! One video with my two favorite UA-camrs and Jens!
I literally said “NOPE” at the same time out loud at 6:28 and laughed my ass off
I’m loving the consistency
Add the acceleration of you toward earth + the acceleration of the earth toward you.
Techniquely, you substract it. But the y both go in opposite direction. And negatives times a negatives is positive.
F = GMm/r^2
|a (tot toward each other)| = |a earth| + |a you|.
The force have equal norm.
ar^2 = GMm/m + GMm/M
ar^2 = GM + Gm
ar^2 = G(M+m)
ar^2 = GM(1+m/M)
a= G(m+M)/r^2.
The center of mass is pretty much where the center of the earth is.
If m
I thought it had to do with the properties of the gravitational force. The earth(or any body for the reason) exerts forces of different magnitudes in such a way that the accelerations of the bodies are the same.
Brilliant, fun, and informative. You guys are awesome. Thanks for doing these! It's 138N, btw. 😂
I think we need to calculate also the weight. Then the force becomes 828N if g=10ms^(-2).
@@leonayt3604Yeah ikr
question 7. (correct any math errors i did this mentally without access to paper and pen)
M = 69Kg, w = 690N
v = 1m/1s=1m/s
a = v-u/t = 1m/s^2
F = mg + ma = 759N
that would mean he is shitting 759/10 = 75.9kg at 10m/s , that king of explosive diarrhea is quite literally ground breaking
To get to 1 meter in one second, you have to accelerate at 2m/s^2. After one second the speed is 2m/s and it is zero at the start. The average velocity in that 1 second period is then 1m/s^2.
this has been one entertaining hour of brainrot lmao. Thank you guys, awesome videos as always ! :D
:3 Glad you had a blast
love the double episode
JEE meme was gold :DDD
Problem: "Bro, I'll make it simple, there's just an object on an inclined plane, you can go on and calculate the fo..."
Flammable maths: "TIME TO FIND THE LAGRANGIAN"
Older Andrew vibes! Love it!
🤣 On the last question, assuming no air resistance and no friction from the toilet seat: He reaches apogee of 0.0509684 m in 0.1019368 s. We have an average force of 700 N when adjusted for significant figures.
Im an Electrical Engineer we called H the magnetic Field in the 2nd half of the program, it was like what's these lies? B used to be, B i think is the magnetic field density of the material because of Mu of the material
Question 7) mass = 69kg, average change in velocity = 1m/s.
Average Force = mass * average change in velocity/total time = 69kg * 1m/s/ 1s = 69 Newtons.
When he said explosive, he really meant explosive
You need a force of 138 N to raise it two meters without gravity. With gravity it would be 814.2 N.
Correct me if I'm wrong.
in a vacuum yes, but the force of gravity acting upon him is around 676.2N so the force needed to lift him would be 69 + 676.2 = 745.2N
Q.6 (according to me is)
F(due to gravity)=mg ......{eqn 1}
well by newton's second law we know that
F=ma .....{eqn 2}
so substituing eqn 1 in eqn 2
mg=ma
m and m got canceled
g=a (which is fact)
and hence proved mass doesnt play role in it and is considered negligible not for small obj but for all.
Yes but also consider that GPE is something that is shared between two objects so as the small mass moves towards the large mass, the large mass also moves towards the small mass(which is why small mass must be specified such that the movement of the planet towards the mass is negligible)
Andrew, you should make a physics book tier list, like E&M Griffiths S tier, Jackson Btier, Pathria A tier...
7 pm in the morning is literally me
Loved this! I really miss the collabs with both of you and Zach.
I have a mechanics exam in 32 hours. this is my review
7 PM in the morning lol🤣🤣🤣
:DDD
As an engineer I am appalled by the incorrect unit conversions
How disapointing seeing Jens use 10 for G instead of Pi²
Only the mightiest.
10:45 you could also say that since the distance traveled in free fall, and consequently the time of such a trip, is only dependent on g and the initial velocity in the y direction
D=(v_O)(t)+0.5gt^2
You guys should have Zach write the questions next time
You laugh you Number Theory
“Some of you know him by worse names than that”
[m]is negligible because acceleration due m on earth would be very very small.
Actually, I am practising shorthand writing on you, while listening to you. Your topic is interesting.
8:42 assuming they mean linear velocity, you can never have a constant velocity if the question is about rotations since the direction is always changing lol. Shouldn’t it be constant speed?
1:31 Huh, I wonder what function would have a graph like that?
:^)
Two circles and a quadratic.
I miss this series so much
Unironically watching this to understand how to approach unique problems.😂
I wish You guys were My teachers
Love you both 😍
What is the name of that writing tablet thingy that both andrew and flammy uses?
assuming mass of object is negligible is wrog if object is your mom
The word 'basically' is the only thing i can hold on to in engineering.
Amazing video❤❤🇺🇸
the joke is that italians sleep like normal people because they are. We're all humans regardless of race and the world would be a better place if we were all nicer to each other. It's actually a really beautiful message.
Now I get it 🤣🤣🤣🤣🤣 respect ppl 🤣🤣🤣🤣 so funny
What's the name if the subreddit?
At 18:00, why does flammy invert the x and y coordinates?
One of the funniest videos I’ve ever seen 😂😂😂😂😂😂
Glad to hear it!
Hi Andrew how are you
I honestly thought that 13:53 was hr*s at first, which made me laugh.
It's my first video here and I instantly wondered if he was an engineer
Welcome! ~ Andrew’s Mom 💕
What is the name of the kind of tablet things you both use for writing?
Could you do a video explaining geometric unity?
What tablet is Flammable Maths is using?
A Gaomon PD1560 I believe?
This might be a bit late to the video but how are you and kelly going? I haven’t heard of you two in a long time
Next video idea: you laugh you code? :D
Of one cubic Planck length of fuel can be used to accelerate at 1g for pi/e Planck times and costs 1/phi^10 USD, (where phi is the golden ratio) what is the cost to acceleration ratio in a vacuum in pounds (currency) per pound (force) per pound (mass)
7pm in the morning....
And no marks for me fir spelling weung stuff right hehyt
Christmas came early🥰
Can’t wait for Andrew’s mom’s comment on this video!
Here ya go! Happy Holidays Tewiiiiii 🎄 😊 ~ Andrew’s Mom 💕
Hey flammable m.aths it's my request please do videos on algebraic topology and algebraic geometry
And stochastic differential equations please if you can't please Andrew make videos on this
Question 8 was solved incorrectly,
The mass is around 3000N because 0.43 was accidentally written as 0.48 which might have affectedthe calculation
We do string theory second year for jee
Epic
Where's my mistake: In the Lagrange question, isn't the vertical coordinate r * sin(phi), therefore the potential U = mgr * sin(phi) making the velocity gt * sin(phi)? Why the cosine?
this video is cursed
yeye :^)
What is the background music?
138N?
Isn't the last question just 69000N?
Wait no its 69 I'm dumb lol, I saw the kilo in kg and immediately thought to multiply by 1000😂
@@atheoristspointofview7059 :DDD
1st question why we need to divide by 10
ben affleck that u??
No but yea idk the inertial mass = gravitational mass canceling shows that independently of the absolute value of the masses you will get the same acceleration for both bodies if the fraction m/M is the same ect. Jens’s argument shows that if that fraction is close to 0 then you can think of the gravitational field of the big mass as being rigid and constant in space thereby it turns into approximately a test mass problem, where the small mass accelerates as if the gravitational field of the large mass and the large mass is pinned in place and does not accelerate at all. You are both right sort of, but questions like this sort of also has to be framed in a precise way to a degree that it implies the correct answer exactly, and i think both explanations added together does that, but Jens also assumed this when he assumed the little m in the gravitational force equation is the same as the f=ma little m, and did not treat the little m in GMm/r^2 as a kind if independent variable. So half marks for jens and andrew in some sort of struct german competition, but idk i think both are fine for a meme show :). the humor of the question more than made up for it.

I'm an engineering first year student and I solved every single one faster, you should be ashamed
Don't tell me Lagrangians are taught in the first year
Someone was bullied.
