The problem involves calculating the acceleration due to gravity (g) using the formula g = G Me/r^2, where G is the gravitational constant, Me is the mass of the Earth, and r is the radius of the Earth. The original poster expresses confusion about the calculation process.
Participants are actively engaging with the problem, with some providing guidance on how to approach the calculation. There are multiple interpretations of the results, and participants are checking their understanding against known values of g on Earth.
There is mention of potential confusion regarding the values and calculations, as well as the need to ensure accuracy in the results. The original poster expresses uncertainty about the calculations and seeks confirmation.
rock.freak667 said:'g' is already the subject of the formula, so you just need to substitute the numbers into the equation.
nukeman said:Oh. So, it would then turn into:
g = G 5.974x10^24 / 6.37 x 10^6
?
So, would the answer be? 9.378x10^29
? That can't be rigbht
rock.freak667 said:Well 'G' is a constant such that G=6.67300 × 10-11 m3kg-1s-2
And you are dividing by 106,so you can't really get back 1029. Redo the calculation with the value of 'G' in it.
nukeman said:im real sorry, but you lost me with G
How do I do the calculation with Value G in it?
nukeman said:How do I calculate this? First, is this correct?
6.6726 x 10-11N-m^2/kg^2 x 5.974x10^24 / 6.37 x 10^6
nukeman said:next: 9.8200
rock.freak667 said:This is more or less correct.
nukeman said:Is there anyway you can check, or I can be sure?
:)
rock.freak667 said:Well we know that on Earth, g=9.81 m/s2, so your answer should be around that number. (Depending on how accurate your values are)
