density/Buoyancy

Front

What is the formula for pressure in fluids?

Back

P = F/A

Front

Which object has the lowest density in water?

Back

The Ping Pong Ball because it floats to the top.

Front

Front

How does pressure in a fluid change with depth?

Back

The pressure in a fluid increases with depth.

Front

What is density?

Back

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

Front

What is the unit of density?

Back

Kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³).

Front

What happens to an object with a density less than that of water?

Back

It will float.

Front

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

Back

It will sink.

Front

What is buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid.
