IB Physics Lab

Title: Astrophysics Lab

Purpose: Is it possible to calculate the mass of a planet due to the rotational period and distance from the planet of the moon?

Hypothesis: It is possible to calculate the mass of a planet from the rotational period and distance, based off of the gravity of the moon.

Variables:

Independent Variable: circumference, period of rotation, seconds around the planet, radius

Dependent Variable: the accuracy of the measurements and math.

C = 34871.678  = 241.19 = p  = 2938734.519  M = 1.74 x 10^-4

1.74 x 10^-4 x 10^25 = 1.74 x 10^21

X = 8.3

Y = 12.3

Radius =  = 10.3

10.3 x 1000 = 10,300  = 63.83 seconds

Conclusion

(6.29 x 10^-5) x 10^25 = 6.29 x 10^20

X = 7

Y = 10.2

Radius =  = 8.6

8.6 x 1000 = 8600 = r  = 118.03 seconds around the planet

C =  C =  C = 54035.39  = 457.81 = p  = 3,034,763.17  M = 1.80 x 10^-4

1.80 x 10^-4 x 10^25 = 1.80 x 10^21

Conclusion: I found the mass of a planet from the rotational period and distance from the planet of the moon. The planet used in my scenario was Uranus, and the moons used were listed above.
