Story summary
- Objects sink when their weight exceeds the buoyancy force, which equals the weight of water displaced.
- A steel block sinks while a styrofoam block floats due to density differences.
- Neutral buoyancy occurs when an object neither sinks nor floats.
- Humans are close to neutral buoyancy because they are mostly water.
- Ships, including aircraft carriers, float due to their shape and large volume.
