SUMMARY

The discussion focuses on investigating buoyancy through practical experiments, specifically analyzing why certain objects, like candles, float while others do not. The participant conducted an experiment with candles, observing that a shorter cylindrical candle floats on its base, whereas multiple identical candles float on their side due to their combined surface area. The need for further tests to gather detailed information is emphasized, particularly regarding the concepts of center of buoyancy and surface area.

PREREQUISITES
  • Understanding of buoyancy principles
  • Familiarity with Bernoulli's Equation
  • Knowledge of surface area effects on floating objects
  • Basic experimental design skills
NEXT STEPS
  • Conduct experiments on the center of buoyancy with various shapes
  • Research the relationship between surface area and buoyancy
  • Explore Bernoulli's Equation in practical applications
  • Investigate the effects of different materials on buoyancy
USEFUL FOR

Students studying physics, educators teaching concepts of buoyancy and fluid dynamics, and anyone interested in hands-on experiments related to circular motion and pressure.

Homework Statement


Analyse the physical world around you in terms of Circular Motion/ Energy/ Momentum / Pressure/ Buoyancy/ Bernoulli's Equation.

Choose one aspect you would like to investigate further.

Homework Equations



e.g. why some potatoes float and other do not

The Attempt at a Solution



I tried using candles due to not having potatoes. I noticed that the candles float on the side with the greatest area. In other words, a shorter cylindrical candle floats on its 'base' while several identical candles combined floated on their side.

If this is a bit too advanced ( never covered centre of buoyancy and surface area), I could try something else. Any ideas?

Addendum:

I am supposed to do some tests to collect detailed information as well.
