Final answer:
When the mast of a ship is raised or lowered, the Center of Gravity (CG) or Center of Mass (CCG) moves accordingly, affecting the ship's stability.
Step-by-step explanation:
The student's question refers to the concept of Center of Gravity (CG) or sometimes termed as the Center of Mass (CCG), which is a physics concept. As the mast raises and lowers on a ship, the CG or the CCG also moves. This is because the position of the CG changes with the movement of mass within the system. In the context of a ship, the mast is a significant part of the ship's overall mass. When the mast is raised, the CG moves upwards, and when the mast is lowered, the CG moves downwards. This shifting of the CG can affect the stability of the ship, as the position of the CG relative to the base of support impacts the ship's balance.
