Question

how do you get an answer to Fg=m1m2/d2

Answer 1

Do you mean \[F_g=G\frac{m_1m_2}{d^2}\]Is there a specific problem you're trying to apply it to?

Answer 2

yes thats it and i have a test on it and i dont have a clue on how to to do it

Answer 3

what was the test question?

Answer 4

no i have a test tomorrow

Answer 5

I apologize if I'm starting too far back...do you know what the variables represent?

Answer 6

are you reviewing from a practice test or something?

Answer 7

yes im reviewing and i know what the variables mean

Answer 8

Ok, I didn't want to be condescending, but I also don't want to assume anything. Give me a minute and I'll see if I can find a representative problem for an example.

Answer 9

ok

Answer 10

two masses with their centers a distance apart of 10,000m
m2 is 20,000kg m1 is 30,000kg
what's the gravitational force either mass experiences?

Answer 11

fg=30000*20000
-------------
10000 * 10000
fg=6

Answer 12

not bad, you forgot the constant though...

Answer 13

G*6

Answer 14

Almost, you need the gravitational constant.

Answer 15

Sheesh. Like racing a machine. :P

Answer 16

look at the equation he showed you... see the giant G ?

Answer 17

it's a constant, check your text for the value.

Answer 19

6*9.8=58.8

Answer 20

not that constant...

Answer 21

capital G

Answer 22

6.67300 × 10-11 m3 kg-1 s-2

Answer 23

ok thanks i get it
