this is waaaayyyyyyy better than my physics teacher.

i cant believe im sayin dis(coz i HATED physics) but im starting to love it! Yikes!

[zakayron8001]

just so no one memorizes it wrong: 1 atm= 101325 Pascals not 103000

[kami645464]

Isn't 1 atm = 101325 ~ 101000 ? Or am I getting this wrong ?

Thank you, I'm actually having fun with this.

in my physics class my professor drew the same thing and everyone thought he was drawing a DiICK! Guess what the professor said! : " I dont know where you get that from but that's not physics(Russian accent )

@dinmorerengeit

You are right. The error was in his part when he said that an atmosphere was 103000 N/m^3, (almost at the end)

while it is actually 103000 N/m^2

u r great, thank u, other parts r also good

LISTEN TO SAL, THE HARDEST PART IS TO MAKE SURE YOUR UNITS ARE RIGHT!!!!!!!!!!!!!!!!!! DON'T FORGET THAT!!! You will get a wrong answer in the test if you do. It will hurt a lot because one may think "wow I watched the whole video and understood it" and then one misses the smallest detail possible and it counts 0. Good vid.

[dinmorerengeit]

is it just me or does the units not work out..?

isnt N= m*a = kg*m/s^2?

N =/= kg*m^2/s

wich means he will not end up with .77m in his answer..

Think you got your atm to pascal conversion wrong buddy. Cheers for the vid anyways.

@g37muflih force has to do with mass and accel/gravity. Pressure is force over an area. Force doesnt need to stay constant, but pressure in liquid does.
