Study Notes
Buoyancy and Fluid Pressure
- Buoyancy is also known as upthrust.
- When an object is submerged in a fluid, the pressure at the bottom of the object is greater than the pressure at the top.
- The magnitude of the buoyant force is proportional to the volume of the fluid displaced by the object.
- The buoyant force can keep an object afloat when the weight of the object is equal to the weight of the fluid displaced.
Objects in Fluids
- If an object has an average density greater than the fluid in which it is submerged, it will sink.
Ancient Greek Terms
- The word 'Eureka' means "I have found it" in Ancient Greek.
- The term 'heuristic' refers to a method of discovery or a guiding principle.
- In the Greek pronunciation, the accent falls on the first syllable (EU-reka).
- In the English word 'Eureka', the accent is placed on the second syllable (E-uREKA).
- The word 'heurískō' means "I find" in Ancient Greek.
