How to Linearize Data for Solar System Motion Analysis?

Click For Summary

Homework Help Overview

The discussion revolves around the linearization of data related to the motion of objects in the solar system, specifically focusing on the relationship between their orbital periods and average distances from the Sun. The original poster presents a dataset that includes periods in Earth years and distances in astronomical units.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • The original poster attempts to plot the data and considers various transformations, such as taking the square root of the horizontal axis data, but encounters difficulties in achieving linearization. Some participants suggest changing the scales to logarithmic, while others hint at underlying laws without providing explicit guidance.

Discussion Status

The discussion is ongoing, with participants exploring different methods to linearize the data. Some guidance has been offered regarding the use of logarithmic scales, but no consensus or clear resolution has been reached regarding the best approach to take.

Contextual Notes

There is an indication that the original poster may not have been informed about relevant laws governing the relationship between period and distance, which could affect their understanding and approach to the problem.

Hi,
I'm supposed to linearize this set of data:

"Below is a data set which includes information about the motion of the objects in the solar system. Note: the periods are listed in Earth years (time it takes the Earth to complete one orbit around the Sun) and the average distances are reported in astronomical units (1 au is a an average distance from Earth to the Sun)."

Period (yrs)

0.241

0.615

1.00

1.88

11.8

29.5

84.0

165

248

Average Distance (au)

0.39

0.72

1.00

1.52

5.20

9.54

19.18

30.06

39.44

So I plotted it, and it turned out looking like this:

Since this looks like a square root graph to me, I took the square root of the data on the horizontal axis and plotted that. However, that ended up looking like a quadratic. In order to linearize that I would generally square the data on the horizontal axis, however that would just give me the original data again. I am stuck and do not know what to do.

After I graph and linearize it, I am supposed to "Create the mathematical model (equation) that describes the relationship between the period of an object and its average distance from the Sun. Show all work." and since I cannot linearize the data I do not know the relationship between the Period and Average distance.

Thanks in advance for the help!

Ps: Sorry if this is in the wrong forum I was not sure where to put it

Change the scales on the axes to logarithmic scales. This can be done automatically by your graphics program.
 
If the teacher has not told you about the law, and he wants you to find it out for yourself ...
This law is one of the great achievements of the human mind. Look at my avatar. (I can not help you more without spoiling the task)
