What are the two primary forces acting upon a floating boat that affect stability?

The two primary forces acting upon a floating boat that affect its stability are buoyancy and weight. Buoyancy is the upward force exerted by the water, which counteracts the weight of the boat. It is this principle that enables the boat to float in water. The distribution of buoyancy also contributes to the boat's stability; the center of buoyancy must align with the center of weight to prevent tipping.

Weight represents the downward force due to gravity pulling the boat and its contents towards the bottom of the water. The balance between buoyancy and weight determines whether a vessel will float, sink, or capsize. When the weight of the boat exceeds the buoyant force, the boat will become unstable and potentially submerge.

Understanding these two forces is crucial for boat operators to ensure safe and stable navigation.
