Final answer:
Buoyancy, displacement, Archimedes' principle, positive/negative/neutral buoyancy, and applications of neutral buoyancy are key concepts in understanding why objects float or sink.
Explanation:
Buoyancy:
- Buoyancy is the force that makes things float.
- Displacement refers to the act of moving something from its place or the measurement of the volume of fluid displaced by a submerged object.
- The difference in whether a ball of tin foil sinks or floats is determined by its density compared to that of the surrounding fluid.
- Archimedes figured out that an object will float if its weight is less than the weight of the fluid it displaces.
- An object with positive buoyancy will float when placed in water.
- An object with negative buoyancy will sink when placed in water.
- An object with neutral buoyancy will remain suspended at a specific depth when placed in water.
- Neutral buoyancy is useful in applications like submarines and hot air balloons where stable positioning in a fluid is required.
