Final answer:
The correct answer is option TRUE. Planing hulls are designed to ride on top of the water and tend to be fast, while displacement hulls push through the water and are typically slower.
Step-by-step explanation:
The correct answer is option TRUE. Planing hulls are designed to ride on top of the water and tend to be fast, while displacement hulls push through the water and are typically slower.
This can be explained by the concept of buoyancy, which states that an object will float if the buoyant force exerted by the fluid it displaces is greater than its weight.
A planing hull is designed to create lift as it moves through the water, allowing it to ride on top of the surface and reduce drag, resulting in higher speeds. On the other hand, a displacement hull is designed to displace a large volume of water and move through it, which creates more drag and slows the boat down.
The correct answer is True. Planing hulls and displacement hulls are concepts from physics that pertain to how different ship designs interact with water. Planing hulls are indeed designed to ride on top of the water and are used for high-speed boats.
When the boat's speed increases, the hull lifts out of the water, reducing drag significantly and allowing for greater speeds. Meanwhile, displacement hulls are designed to move through the water. They push water aside as they move, which creates more drag and results in a slower velocity.
These dynamics are crucial for understanding the performance characteristics of various boats and ships.
For example, longships built by the Vikings were designed for both speed and agility by utilizing narrow hulls and shallow drafts, enabling them to move quickly and efficiently on water and venture into shallow waters.
In contrast, large merchant ships, which prioritize cargo capacity over speed, typically feature larger displacement hulls, providing the necessary buoyancy to carry heavy loads while moving through the water at slower speeds.
