If anyone wanted to know pascal = kgm-1s-2 hertz = s-1

[@RWC-Ichigo]

How did you work out Hertz

[@senathrandila8874]

@@RWC-Ichigo frequency= 1/ T. so T=seconds. therefore f= 1 / s. bring s up and therefore it becomes s-1.

The S.I. base units are fun to learn, but I wish that all Americans should use such units in day-to-day life. :-)

[@simpleqaseem1655]

Daniel Luster no because than every thing will be difficult you know how example newton saying 15N instead 15kgms^-2

Hmmm .. Impressive☺

[@seamad8117]

I just need to know at 4:47 why you put -2 in front of s but only 2 in front of m. Aren't they both squared??

[@hunainzulfiqar9757]

they are but example acc is m/s2 but we often write it as ms-2 so thats what he did like we just shift 2 to the numerator and so we change the sign. do you get it???

[@seamad8117]

@@hunainzulfiqar9757 not really

[@hunainzulfiqar9757]

@@seamad8117 well if you move any thing from denominater to numerator you change the sign so +2 becomes -2

Why is mass misured in kg (1000 g) instead of g like all other units?

[@reesebonin9890]

99% of the time grams are too little to make a good use of. Hell even kilos are hard to use at times.

[@_Ekaros]

Because revolutionary French thought that Grav that is 1 Grav = 1 kilogram were too big for the masses... So they came up with smaller unit, messing up the whole thing...

[@aaronennis1195]

what is the difference between SI units and SI derived units?

[@rosebloze6829]

Si units are the main units which are 7 in number whilst derived units are units gotten from the main units which are known as the fundamental units

[@soumyadeepkarmakar4679]

What about Resistance (ohms)? Is that base SI or derived SI?

[@callumvoh]

Ohms is derived SI

doing physics and have to learn the metric system kinda sucks. Not the system itself just wish America would teach this in middle school because almost all the rest of the world uses the metric system

Why Power is not considered as a derived SI unit

[@hassankhan1426]

it is a derived unit dude

[@onigrace8411]

why didn't you derive Hertz and Pascal?????

[@ahmadabushariha5833]

idfk, lazy **

[@ahmadabushariha5833]

i lost a mark for pascal in my external, in circles, if he just solved it...fu*kin hell

[@WyvernApalis]

Oni Grace he literally just said don't use capital for those two

[@didiivi8924]

ahaha

[@bloodwolf2609]

because it's not hard? he taught you how to do it for the other two so its really not difficult to apply the knowledge to the other two equations.

is kgms-2 a base unit and newton(N) a derived unit?🙁

[@aimanghazi7043]

yes (base units) and yes :D

Newton is not a drived unit it's just the name of the basic unit and it is used for ease And kgms-2 is basic drived unit

[@lanapshtiwan2117]

You write the symbol for velocity and you say speed which is just confusing and not right scientifically.

[@mayakevlani5376]

Lana Pshtiwan speed and velocity have the same symbol and you are right because velocity is the rate of change of speed in a specified direction

[@serrendiptiy]

Why do none of these explanations start by telling you what we mean by 'derived'? Does it sound silly that we use upper case just because a term is named after a Lord? i.e. Kelvin? who cares whether it's upper case or lower case anyway?
