Frequently Asked Questions (FAQ)

• How do you calculate the mass of fluid displaced?

• To calculate the mass of fluid displaced use the formula m = ρV, where ρ is the fluid density and V is the volume.

• What are the 3 types of buoyancy?

• There are three types of buoyancy: Positive buoyancy is when the immersed object floats because it's lighter than the fluid displaced. Negative buoyancy is when the immersed object is sinking because it's denser than the fluid displaced. Neutral Buoyancy is when the immersed object is neither sinking nor floating because it's weight is equal to the amount of liquid it displaces.

• What is the SI unit of buoyancy?

• Buoyancy is measured in Newtons (N).

• How does mass affect buoyancy?

• If an object weighs more than the fluid it displaces, the buoyant force acting on it will be less than gravity, and it will sink. The more mass the immersed object has, the deeper it sinks.
