Tension in an accelerating system and pie in the face

[LaGail4]

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.

" figure out how much we need to accelerate a pie for it to SAFELY reach a man's face." LOOOOOOLLLL =)) =))

[31reggiemiller1]

i hate physics because nobody teaches it to me like this guy

[KoolioJosh]

his was on my physics exam, and i was prepared!

[TheKcsmithy]

love the video really good

[samjenkinssam]

you have some great stuff here

[Oocheri]

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

[prchecker]

really informative and interesting

[Kricardose]

I am very happy to see the vidoe 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 after you give this

[bebeheuy]

I Love The Video The second part to the complicated problem. We figure out the tension in the wire connecting the two masses It Can Increase My Knowledge

[Mjhond]

Steady I Really Like This Video The second part to the complicated problem. We figure out the tension in the wire connecting the two masses.

[MrPEDOCTOR]

Im lost in these video.

[koolspaz]

where is the previous video that solves the pulley with an inclined plane?

[applecounty]

Thank you from a grateful parent.

[Fr0gles]

heres the address for the first part of this video

watch?v=KdoBDjvee3U

[Dejimon458]

anyone else doing this in high school and think it's bullshit?

[theonetrueac]

check the old physics playlist, not sure if it's there, but this looks like an older video...

[MrBazingafy]

Can somebody help me find the first part.

[007abhinavagarwal]

where's part 1 ??

[warvad]

Where is part 1?

[m1234n1234]

thankyou

[WontonSandwich]

lets not focus on the drawing *draws hair and mustache

LOLOL :D

[RHCP1233]

"you can see i was destined to be an artist"

shit yes you were. that face is rad

[kx32ta1]

I am no expert but you have tension and mg both going in the positive direction. Shouldn't it be T-mg=ma which would give T=ma+mg =279. For anybody reading this make sure you double check how to find tension because cramster along with physics forums say its the other way. Thanks for the videos though, just wanted to double check

[kurozaki45]

@kx32ta1 how are the tension and mg going in the positive direction the tension is up mg is down for the second object isnt it? and for the second object tension is going right mgsintheta is going the opposite way

[will8831]

"I am destined to be a great artist" Lol sal you're the best

[dalcde]

I'm thinking of checking your calculation with the pie.

[gerrenx7]

That face is actually pretty good

[akondude]

Another way to do it would have been to say 9.8-4.13 which is 5.67

and then find out the force if it was accelerating at 5.67m/s2

F=20x5.67=113.4

[WannaBeiDev]

doesn't the tension goes clockwise(down) at +113N

[nowandforever117]

Video's are very good. You explain everything. 10/10 for sure! thank you

[6bikal6]

ya your drawing is very good

..

[qaipak1]

Nice drawing =D

[wexarexthexStorm]

"Let's say he has a mustache"

LOL

[J4IMEE]

creative and smart ;)

[yyAjax]

the face was excellent tho

[deathbystarship]

3.14 in the face

[HowToDo92]

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"

[fibreoptics]

if Tension is independent of friction then we can straight of calculate the Tension of whole wire that

is 130.6N by 2.m1.m2.g/m1+m2

according you too the tension is

16N + 113N = 129N

[Stretch427]

Love your video's, they are very informative!

[alexdisla01]

I tried calculating the tension using the other object, using the Fp and the Ff and it did not work. I am probably doing the wrong thinking. Please, how would you do it?

[jackshay01]

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

[sumfinunique]

il make it bald.. i shouldnt be doing this.. lets give it a moustage.. well anyway.. HAHAHA

[xlwaiyiplx]

good artist

[punjabanjii]

i like ur drawings

[punjabanjii]

hahah

[Mizumi17]

haha i love how he gets side tracked for a while on his drawing xD

[Sharp12]

OLOLOLO wow this was more funny than it was educational. Well i'd say they are both equal

[Snakk3]

and how can i calculate the tension by using the other object?

i thought it was the force of gravity paralel to the surface + force of friction... but it isn't...

[pieface1726]

this man is getting me through my A-Levels, i love you!
