Sink

Front

What is density?

Back

Density is the mass of an object divided by its volume.

Front

How do you calculate density?

Back

Density = Mass / Volume

Front

What happens to the density of an object if its mass increases while its volume remains the same?

Back

The density increases.

Front

What happens to the density of an object if its volume increases while its mass remains the same?

Back

The density decreases.

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 it is in.
