Back

D = m/v

Front

What happens to an object with a density greater than water?

Back

It will sink.

Front

What is the relationship between buoyancy and density?

Back

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

Front

What is the principle that explains why ships float?

Back

Archimedes' principle.
