What neutral buoyancy means in practice
Neutral buoyancy describes a balance between buoyant force and weight. It is a physical condition rather than a body position or a permanent setting. Practical control requires supervised learning.
An example to think through
A drawing shows a diver tilted head-up while the upward and downward forces balance. The drawing can describe neutral buoyancy even though the body position differs from a horizontal diver. Use it to separate buoyancy from trim.
A common misunderstanding
Neutral buoyancy and horizontal trim are different ideas.
Underlying concept: OpenStax, College Physics 2e — 11.7 Archimedes’ Principle. The example is an original YouDive study prompt, not a reported dive.
