What is buoyancy?
Consider how objects behave in water.
What does Archimedes' principle state?
Think about displaced water when an object sinks.
What does Archimedes' principle state?
Think of how objects behave in water.
True or False: The center of buoyancy is the centroid of the displaced volume.
Relate this to how shape affects buoyancy.
A 2 m³ block of wood with a density of 600 kg/m³ is floating in water. Calculate the depth to which the block is submerged. (Density of water = 1000 kg/m³)
Use the volume ratio based on densities.
An object has a weight of 300 N when submerged in a fluid. If the buoyant force acting on it is 350 N, will the object sink, float, or be neutrally buoyant?
Compare the weight to the buoyant force to assess floating vs. sinking.
