Front

What is buoyancy?

Back

The ability of an object to float in a fluid.

Front

What is the principle of buoyancy?

Back

An object will float if it displaces a volume of fluid equal to its weight.

Front

What is the relationship between density and buoyancy?

Back

An object will float if its density is less than the density of the fluid.
