Anyone know of a way to solve for gravity of a planetary body without using the gravitational constant?
Solve what? You haven't stated what is given.JD Duncan said:Anyone know of a way to solve for gravity ...
You were given a method and you rejected it because you said the information needed wasn't available. Are you going to give the same response for any method given? What information is available? We can't answer the question if you won't tell us the constraints.JD Duncan said:It’s not a specific value calculation. I’m asking about method. Do you know of a way to find a body’s gravity, in equation form perhaps, without using the gravitational constant to find the answer.
Where you coming from? I haven’t rejected anything. It’s a general question, not a specific problem. No other info needed.russ_watters said:You were given a method and you rejected it because you said the information needed wasn't available.

But what can be used?JD Duncan said:... without using the gravitational constant to find the answer.
You rejected the use of satellite trajectory data.JD Duncan said:Where you coming from? I haven’t rejected anything. It’s a general question, not a specific problem. No other info needed.
Drop something and measure its acceleration.JD Duncan said:If you can think of several other methods that require different known data then list them because that’s exactly what I want to know.
JD Duncan said:You’re a staff mentor? Dude. You have a terrible disposition.

Little g (g) refers to the acceleration due to gravity at a specific location on Earth's surface, while big G (G) is the universal gravitational constant that is used in the equation for Newton's law of gravitation. In solving for gravity without gravitational constant, we use g instead of G to account for the variation in gravity at different locations on Earth.
Little g can be calculated using the formula g = GM/R^2, where G is the universal gravitational constant, M is the mass of Earth, and R is the distance from the center of Earth to the location. This formula takes into account the variation in Earth's mass and radius at different locations.
Yes, we can use little g to solve for gravity on other planets. However, the value of g will be different on each planet due to differences in mass and radius. The formula for calculating g remains the same, but the values for M and R will be specific to the planet in question.
Solving for gravity without gravitational constant allows us to account for the variation in gravity at different locations on Earth. This is important in fields such as geology, where the strength of gravity can affect the behavior of materials and structures. It also allows for more accurate calculations in fields such as space exploration and satellite technology.
While using little g can provide more accurate calculations for gravity on Earth, it does have limitations. The formula for calculating g assumes a spherical Earth with uniform density, which is not entirely accurate. Additionally, it does not take into account other factors that can affect gravity, such as topography and atmospheric conditions. Therefore, it is important to use g with caution and consider other factors when necessary.
