omfucking god, Mr. Galifinakas thank you so much, i thought you were an idiot after watching you in the hangover but your actually very bright young man <3

[PhysicsEH]

@yellopanda I never noticed the resemblance. I'll bug him about it.

[WanderleiCornell]

thanks brah

[PhysicsEH]

@WanderleiCornell Glad to help.

the chalkboard and chalk writing looks so clean lol!

[PhysicsEH]

@MiturBinlsderty That took lots of practice and we washed the board between takes. Thanks for noticing.

numbers, letters and more numbers.. Tell me how it will help me move logs :P lol...

@TerminatorToast you're right, I saw the same thing. They didn't multiply by acceleration of gravity which they should have done, they just left it as 5g for some reason

[Klegend1000]

can you teach me about the equations and stuff? I havent really reached highschool yet

[Atadavidl]

You taught me more in 5 mins than my physics teacher could in 1 week. AP Physics B lifesaver

[pfvc95]

Thank you so much!

[seragreen]

is there a video where you explain how to calculate the total net force acting on a system?

[TerminatorToast]

Isn't the acceleration of the system 3.27m/s^2?

The answer you got (.33 m/s^2) is the answer I got (3.27 m/s^2) divided by gravity (9.8 m/s^2).

Is there any reason you did this? Please respond I'm so confused!

My work:

10g-5g=15a

98N-49N=15(kg)a(m/s^2)

49N/15(kg)=a(m/s^2)

a=3.27m/s^2

@Bakugantsuvai1 Alright. So much like here. I am OK for you not telling me, because the "uncomfortableism" just so that's said. :) I respect you very much. Thank you for all your help and I wish you the very best luck at the rest of your life! :)

@PatrickVedlog Since I am uncomfortable telling you my grade in school all I can tell you is that I am nearing high school graduation. In my country right now we do not start physics until around second year of high school which really stinks because the honors science kids start doing this stuff in 5th year of primary school. So I asked my primary school teacher if I can go into science honors and she said I will not succeed in the course such outrage

@Bakugantsuvai1 Here in Norway, we start with physics and such the second year of High school. We have like Math, English, Norwegian, Science and such. But not deeper into science. That's for next year. Hopefully, next year I'm studying in London. Oh! I didn't ask. What grade are you in? Good luck friend!
