This chanel save me form failing my physics

[@canaeh3692]

because of you, I study physics for fun now, your awesome bro keep up the good work.

[@Arcaeau]

Same😊

[@PavlosAssimenos]

You're the best teacher I've ever seen, the details, the information, and the explanations are all crystal clear and concise! Now I'm determined to overcome the hardships of my exams, have a great day.

[@hnnahye]

this channel is the only thing saving my ap chem grade rn

[@shreenidhhi8633]

U have atmospheric pressure for ap CHEM?

[@hnnahye]

@@shreenidhhi8633 yes, but just the basics like using the formula (P= F/A)

[@gnation855]

Same here

[@safiulfaiyaz7038]

And here I am leaning for AP Physics 1 & 2. I have always regretted taking AP Biology over AP Chemistry, was I wrong or right in this decision? what do you think?

[@ItsEthanErosion]

Bro it's not chem it's physics 😂

[@proximparadox5586]

At 4:25 he was like " lemme just use the calculator" lol

[@ElizabethAfolayan-fg3ne]

I love ur teaching sir

[@sizakelembatha6379]

Why is the 101.325 now 101 325 without the comma? At 11:57

[@mahmoudabdellrheem2364]

1:53 the atm is equal to 101,325 kpa not pa

[@safiulfaiyaz7038]

no it's not check with google

[@AhmedSalah-sr3os]

I love you man 💙

[@lm58142]

1:22 "..so that's really what atmospheric pressure is - it's basically the weight of all the air molecules above a given area." If that was the case, we would see a pressure drop inside a sealed container.

[@philindeblanc]

thats a very good point. how do we weigh the unpressurized pressure of the contained air?

[@lm58142]

​Thanks. The pressure inside the sealed rigid container seems to be caused by capturing a sample from the bottom of the 'gas ocean' where the air density is higher causing more molecular collisions with the walls of the container (or a pressure gauge sensor). However, it gets interesting again when we try to apply that explanation to the hydrostatic pressure, as the water density varies insignificantly with depth, yet the pressure inside the rigid container sealed underwater at depth does not disappear. One may be tempted to say that water molecules at greater depths have higher kinetic energy which causes higher pressure readings inside the containers sealed at greater depths despite unchanged density, but that means water temperature would be higher the deeper we dive, which is not the case.

[@erwinconxepts]

atmoapheroc. pressure is not the weight of the air,.its a common misconception about atmospheric pressure. atmosphere is composed of different gas with different weights.

[@vijaymalhotra1733]

Air by the definition means mixture of gases. So need not be specifically mentioned

[@philindeblanc]

Its actually not. We can produce different gases from the air, but the gases are not a constituency of the air.

[@oru_naadan_alchemy]

thanks a lot sir.could you please explain that, what would be the pressure exerted by the fluid on the walls of the container . thank you.....

[@jhanolaer8286]

Given the pressure can we calculate the velocity?

[@CelineOwusu]

Thank you so much for ur effort

[@ericplanos6050]

sir, how did you get the 1.03x10^6 kg?

[@eldergod2486]

It is easy

[@albertnaura4854]

That's the standard atmospheric pressure

[@Sohlstyce]

that's the pressure of the atmosphere.

[@philindeblanc]

@@albertnaura4854 Ya, but how do you get it? You cant do physics without knowing this. Otherwise you have no basis on what you calculate.

[@NothandoNana]

yeah why coz my calculator gives me 1033.93

[@anilsharma-ev2my]

TWh energy electricity required how much weight pressure and displacement required ?

[@bcjmusic2259]

Thank you.

Work done by an aneroid barometer is what in joules per unit volume ??in Delhi

I wish you were more audible, I can't watch this in class and it's stressing me out tttttt

Why did he use Pascal's at 4:29 and not atm?

😂😂😂😂😂😂😂 😂😂😂 stupid

[@anilsharma-ev2my]

How to calculate strength of containers which holds 10000000x20 cubic volume height How much workdone required to fill this inverted tumbler against atmospheric pressure ? Please show this math

[@orangeyavocado8413]

no

Wow. Thanks man. Wow

[@lucychiu46]

which organic chemistry tuto play list has this video? I can not find it under the physics playlist ?

[@Beep_beep_boop]

On question 3 is the answer not 103 x10^4 not 103 x10^6?

[@Fatimaurl]

which website/app did you use for the writing

[@queensguard4828]

ur mom

[@昂少花]

why does pressure require force to be acting have to be perpendicular?

[@philindeblanc]

weight alone can be the potential pressure. This is why density is a measure potential force. Everything becomes force with motion. But its a good question, does pressure require force? Is there pressure in the first place? At what point is air a perpendicular pressure? Good questions. I dont think I have made sense of it yet. The math works but based on what?

[@fitheeshete2315]

Good job

Hi, how about like an speaker cone that has a mass of around 1.8kg and it moves 3inch iwill convert to meter. Is the total mass of the speaker cone is from cone mass in kg multiply by length of the cone travel?

[@anilsharma-ev2my]

1000 gigapascle required how much surface area ???

[@chantelvilakazi9179]

What can you not do?

[@kingjeremysircornwell7847]

Atmospheric pressure increases sound decreases, motion sickness?

[@philindeblanc]

This might be a MUCH better way to measure atm. The way atm is measured now sounds bogus to me...At least I have yet to find a valid reasoning.

[@alemuasana7234]

where did 101,325

[@shamiraidora8120]

greatt

[@Sohlstyce]

i'm your 101,325th viewer pfft

[@RiteshKumar-bp8dm]

Bro why don't wo count the atmospheric preasure from that object to the sky because air is all up

[@anilkumarsharma8901]

Why air pressures is not used to provide electricity One kilometre area bounded by barometer column will gives so much energy per dey which is stored in the battery and used later in the emergency??

[@scottzajac2542]

Pressure is negative as you rise above sea level. I like the concept but I would think of an inflated balloon in deep sea creating pressure as it rises. The energy required to fill the balloon was ~ to pressure generated is it at that moment with a long term result?

Sir when I read my reference book 1atm=101,000pa.

[@bottleofwater1675]

Fithe Eshete mine says 101.3kPa, I guess the difference is small enough not to be relevant ^^
