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.


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

        Dependent Variable: the accuracy of the measurements and math.

    During the experiment some factors which may affect the result like voltage, temperature, conducting wires, radius of pencil lead etc. are kept constant to prevent some unexpected results. First of all current values which are obtained as a result of the experiment are used to find resistance.

    The wooden ramp was slightly bent at the top due to the force leaning on the table. After the table (going downwards), the wood seemed relatively straight due to the wall supporting it. The top of the ramp did not have any support therefore making a slight bend in the wood above the table mark.
