The second part to the complicated problem. We figure out the tension in the wire connecting the two masses. Then we figure our how much we need to accelerate a pie for it to safely reach a man's face. Created by Sal Khan.

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

where is the first part of the problem?
At Joe's
@@TamedRome WHO IS JOEEEE??
@@galendaly-odonnell68 Joe mama!
I love these lessons, however the lessons are totally out of order. went from tension to suddenly a second part of a problem involving pullies which I haven't even found the first part of yet. Also, please stop skipping operations when manipulating equations. makes it very difficult to figure out what's going on.
Trueeee
where is the previous video that solves the pulley with an inclined plane?
i wish you would give the links of the previous videos... that would be wonderful!
Please make the first part not private:/
i think its emberrassing
I cann't tell how much i appreciate your delicate effort for physics, thanks! one question---Where can i find the part 1 of Tension in an accelerating system and pie in the face ?
"I am destined to be a great artist" Lol sal you're the best
"Well, we knowww...well you dont know this but I KNOW that..." lmfao too funny Sal, love your humor dude
Where is the video before this???
I love watching your videos but in a rush its difficult to watch a section because the videos aren't number. That would help a ton when I'm just trying to review something like tension. This video started somewhere else but I don't know where. Plus its something you can change just through video editing. I realize you have hundreds of videos but just a thought for the future.
"Let's say he has a mustache"
LOL
this man is getting me through my A-Levels, i love you!
lol this always happens in my classes. "haha. this is why im a teacher, not an artist... well this is kinda fun... lets make this guy funny lookin"
and that^ is why i need to come here to relearn the things my teacher is too distracted to teach us
i need the first one so bad..but i cant find it haha. so close.
lets not focus on the drawing *draws hair and mustache
LOLOL :D
Khan, where is the first part of the problem?
Where is part 1?
Thank you from a grateful parent.
Video's are very good. You explain everything. 10/10 for sure! thank you
I'm not sure why you suddenly started using thicker pen font for the last few videos that I've watched, but I find it a lot harder to read..
It's because those videos are recorded long ago and the resolution is only 240p
his was on my physics exam, and i was prepared!
Please Do Nursing Dosage Calculations, PLEASE. I need your help with this class.
the video isn't clear ... but the lecture is;-)
thank you sal
Yeah, especially given the resolution/quality of the lines and such!
imma comment 8 years later for no reason lol
@@jkgan4952 Lol okay :D I have no idea what this was about. But I guess, have a good one!
@@Phagocytosis lol you too!
yeah where are the other classical mechanics videos I can't find them on khan's channel.
That's what I want to know!
seriously where is it? and the same others
check the old physics playlist, not sure if it's there, but this looks like an older video...
so helpful
Love your video's, they are very informative!
thankyou
are all push forces are normal forces?
where is it indeed?
good artist
Amazing video, but now I want pie!
ya your drawing is very good
..
wouldn't it of been easier to think of gravity as 0.8 or 80% of the force needed. so you go (9.8/80)*100=12.25N
lol,, actually tht's not the exact value of pi cuz pie is an irrational number and it nvr ends. lol
but try this. write 3.14 in a paper and hold it in front of a mirror.. tht looks like the word "PIE"
Nice drawing =D
il make it bald.. i shouldnt be doing this.. lets give it a moustage.. well anyway.. HAHAHA
Take away from the video is Sal was a newspaper cartoonist in his highschool. 4:18
That face is actually pretty good
OLOLOLO wow this was more funny than it was educational. Well i'd say they are both equal
This video was made when I turned five
this was made when I turned 13
Leo Wilken was it made on your birthday too
you an noob
omg 2008 !!
great drawing skills up ya sleeves.LOL!!
this link is broken///\\\
sorry for the delay.. :) /watch?v=KdoBDjvee3U
heres the address for the first part of this video
watch?v=KdoBDjvee3U
shame on you, whoever you are who disliked the vid
The problem with Khan lessons is that
A) Its not clear
B) its not in order
C) He explains almost nothing.
D) He goes really quickly and he makes mistakes in the process which forces him to make 1min videos to correct his mistakes..
I don't know why people say that Khan acdemy is so good, its not..
Aye man its better than anything you could do. Don't be talking trash if you cant do better lmao 💀
@@72d So if I cannot direct a 100million budget film, I should not be allowed to comment or criticize it? poor logic.. You should do the logic course of Khan as well.
MathTutorDVD much better. Check it out
@@PeterMasalski93 Dude that's just your opinion. and you should not be taking this is one of Sal's OLD video's (I'm talking 8+ years old)
Of course its not going to be perfect but hey, it still helps people. and that's all that matters. (just scroll though the rest of the comments just because it didnt help you didnt mean it didnt help others.)
@@72d I think you are too thickheaded to understand that comment sections exist for the sole purpose of "GIVING YOUR OPINION". One doesn't need to be an expert or have created similar content to compare and criticize.
- Get lessons in logic, please
- I already solved my problem regarding this video.
