Question

" Thinking skill " Not now... but a problem

Answer 1

@across and @Algebraic!

Answer 2

My question is that :

first of all :

\[\large{g_e = \frac{GM_e}{R_e^2}}\]

Answer 3

@hartnn

Answer 4

@TheViper

Answer 5

is it correct hartnn ? I mean for the formula ..

Answer 6

yes, i think....let me confirm

Answer 7

*not only hartnn but all

Answer 8

confirm it

Answer 9

yup, thats correct.

Answer 10

ya it is correct.

Answer 11

derivation of the above formula :
\[\large{F = \frac{GMm}{R^2}}\]
\[\large{\textbf{Since :}\space F = m * g}\]
\[\large{\textbf{hence :} \space \frac{GMm}{R^2}=m*g}\]
\[\large{g = \frac{GMm}{R^2}}\]

Answer 12

any mistake here?

Answer 13

g = GM/R^2
now it is correct.

Answer 14

oh sorry I meant :
\[\large{g = \frac{GM}{R^2}}\]

Answer 15

ok so now ...
\[\large{a=\frac{F}{m}}\]

is it so ?

Answer 16

ya

Answer 17

yes, F=ma

Answer 18

Ok now? :
\[\large{a \vector = \frac{F\vector}{m}}\]

Answer 19

take that as vector friends:

is it so now?

Answer 20

OK sooo ?

Answer 21

Yes

Answer 22

Mikael is
a vector = F vector / m

Answer 23

Positiff

Answer 24

Ok so "no"

since they are vectors

Answer 25

ya it is all right man
wt r u trying to do actually?
going to fail this law ?????????????????????????????????????????????????????????????????

Answer 26

??

Answer 27

hmm - ?

Answer 28

hmmmm-??

Answer 29

\[\large{F\vector = a\vector .m}\]
\[\large{\text{Can vectors be divided?}}\]

Answer 30

Yes by a scalar

Answer 31

wait ... let me type laTex

Answer 32

la-what ?

Answer 33

\[\large{\frac{F\vector}{a\vector}= m}\]

Answer 34

is it so now

Answer 35

NOOO PROHBLEHM VATSOEVER - BECOZE COLLINEAR VECTORS CAN BE DIVIDED BY EACH OZER !!!

Answer 36

yeah\[\LARGE{\frac{\vec F}{\vec a}=\frac{m \vec a}{\vec a}=m.}\]The way u want;D

Answer 37

is it necessary ? that they r collinear vectors?

Answer 38

MOREOVER, math-loving-krishna-fluting EVEN NON COLLINEAR VECTORS - if we define division as finding a certain transformation matrix with additional constraints

Answer 39

they are collinear man
acceleration is always in the direction of force in inertial frame of reference.

Answer 40

UZHUALLY though people avoid dividing vectors - because many matices satisfy it, and thus the answer is NOT unique matrix.

Answer 41

EXCELLENT..

Answer 42

since u r writing
f = ma
initially.

Answer 43

Who's picture is on your pic ?

Answer 44

And why flute ?

Answer 45

Thanks a lot .... i got it now..

GOD "KRISHNA"

Answer 46

:D

Answer 47

He plays flute.... this is his passion

Answer 48

;D

Answer 49

What is the passion of the butterfly that Dreamed it was Zhuang-tzu ?

Answer 50

you know that flute notes are actual harmonics of the fundamental tone ?
