I forget how these two relate both conceptually and mathematically...any help?

The center of mass is a point in an object or system where the mass is evenly distributed in all directions. It is also known as the "center of gravity" and can be thought of as the average position of all the mass in an object.
The center of mass is calculated by finding the weighted average of the positions of all the individual parts of an object or system. This is done by multiplying the mass of each part by its distance from a chosen reference point, and then dividing the sum of these products by the total mass.
The center of mass is significant because it is the point around which an object or system will rotate if a force is applied to it. It is also used to determine the stability, balance, and motion of an object or system.
The reduced mass is a concept used in physics to simplify the calculation of the motion of two or more objects that are interacting with each other. It is the equivalent mass of one object that is moving in the gravitational field of another object, and is calculated using the masses of both objects and the distance between them.
The reduced mass is used in many equations related to the motion of objects in a gravitational field, such as the equations for orbital motion and binary star systems. It allows for the simplification of these complex calculations and makes it easier to analyze the behavior of interacting objects.
