My problem is understanding this because I have to calculate the mass and radius of 3 planets along with the graviational acceleration and then find the period of a 2 meter long pendulum on each planet for the assignment.

The instructor posted a formula that he used in Excel but there was no explanation.

The formula: =6.67x(10^-11) x 3x(10^25)/(64x(10^12))

Ok the basic formula for the Force attributed to gravity is:

F = {GM/r^2 } m = mg

The constant G appearing in Newton's law of gravitation, also known as the universal gravitational constant,
G is supposed to be a universal constant ...
