Re: Dependance of "g"

you cannot keep \$F\$ unchanged if you change \$m\$. So, the question is mute.

It seems like you are intentionally trying to make the argument longer.

Lets be absolutely specific : Does the value of \$g\$ change if the value of \$m\$ is changed?
Answer Yes or No. No talking about other stuff or weird definition of functions and variables.

Re: Dependance of "g"

হুম, তুমি F এর মান স্থির রেখে শুধু m এর মান পরিবর্তন করে g পরিবর্তন করতে পারবা না। সুতরাং g, m এর উপর নির্ভর করছে না।

Re: Dependance of "g"

Because whatever \$m\$ you put in you always get the same \$g\$. It does not matter how you write the equations, what matters is whether the input changes the output. In this case, it does not. So, the output (\$g\$) is independent of the input (\$m\$).

Re: Dependance of "g"

This discusion has finished long time ago. Tarporo ami kisu bolte chai. Ai baparta nie ami besh kisudin jhamelay silam. Mathmetically it's ok. Kintu ami vabsilam newton er mohakorsho shutro nie. Shekhane ase, 2ta bostur akorshon(F) nirvor kore vorer(m, m') upor. Akhon prithibir vor sthir. Akhon m change korle F change hobe. Abar toron(a) depend kore boler upor. Tai bol beshi hole toron barar kotha. Tahole amra bolte pari bostur vor barie or komie amra prithibir akorshon F barate ba komate pari. & finally a(ekhane g) bere ba kome jabe. So, g is not constant. Bohudin ai problem e silam. Anyone could'nt make me satysfied.

At last i solved.
Konokisur toron ghotate hole boler dorkar. Aki toron ghotate beshi bhorer bostur beshi bol dorkar. Akhon m beshi kore dile F bare thiki, kinto oi beshi vorer bostur aki toron ghotate oi beshi boltuku dorkar.

Bigganke ami evabe bakkhay bujhte chai. Gonit kore shohoje bojha jay, tobe upolobdhi korar mojai alada. Goniter shobkisu ami upolobdhi korte chai.

akashe shurjota othe nirobekome jabe. So, g is not constant. Bohudin ai problem e silam. Anyone could'nt make me satysfied.

At last i solved.
Konokisur toron ghotate hole boler dorkar. Aki toron ghotate beshi bhorer bostur beshi bol dorkar. Akhon m beshi kore dile F bare thiki, kinto oi beshi vorer bostur aki toron ghotate oi beshi boltuku dorkar.

Re: Dependance of "g"

S.S.C এর বইতেই কিন্তু বলা আছে "g এর মান বস্তু নিরপেক্ষ হলেও স্থান নিরপেক্ষ নয়।" তাই g অবশ্যই m এর অপর নির্ভরশীল না।

Re: Dependance of "g"

SSC এর বইতে এই কথাটা লেখা আছে দেখেই আমি প্রশ্নটা পোস্ট করছি । কারণ , গাণিতিকভাবে F = mg সূত্র থেকে আমরা বলতে পারি যে g , m এর উপর নির্ভরশীল । তাই আমার মনে প্রশ্ন আসছিলো এই কথাটার ব্যাখ্যা কি ????

Re: Dependance of "g"

Then we can re-write the thing as, "প্রযুক্ত বল স্থির থাকলে ভরের পরিবর্তন ঘটলে g এর মানের পরিবর্তন ঘটে " but these words has no meaning. As m changes, F changes and g remains the same.
