controlling buoyancy

• what will a positively buoyant object do?

  float
• negatively buoyant objects sink in water
• what does buoyancy depend on?

  density
• If an object is more dense than the fluid it is placed within then it will sink.
• If an object is less dense than the fluid it is placed within then it will float.
• We can make an object less dense by keeping its mass the same but increasing its volume
