  1. States of Matter Fluids

  2. Activty • Will it float? • Rock • Potato • Paper clip • Pen • Pencil • Coin • Candle • Eraser

  3. Objectives • Describe the buoyant force and explain how it keeps objects afloat. • Define Archimedes’ principle. • Explain the role of density in an object’s ability to float. • State and apply Pascal’s principle. • State and apply Bernoulli’s principle.

  4. Describe the buoyant force and explain how it keeps objects afloat.Define Archimedes’ principle.

  5. Pressure Pressure = force / area = F / A Units = Newton per square meter = pascal

  6. Buoyant Force
