Homework Help: Investigating real-world situation

  1. Jan 25, 2016 #1
    1. The problem statement, all variables and given/known data
    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.

    2. Relevant equations

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

    3. 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?

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