The Center of Gravity (CG) is the point at which:

The Center of Gravity (CG) is defined as the point at which an object’s mass is evenly distributed in all directions. In the context of rocketry, this means that there is an equal amount of mass both aft (towards the back) and forward (towards the front) of the CG. This point is crucial for stability during flight; a well-placed CG ensures that the rocket maintains the necessary orientation and does not pitch uncontrollably.

When the CG is properly situated within the rocket, the forces acting on it during ascent, such as thrust and aerodynamic drag, can be balanced effectively. If the CG is too far forward or too far aft, it can lead to instability and can adversely affect the rocket's flight path and performance. Therefore, identifying this point accurately is essential for safe and successful rocketry.
