Physics II Lesson 26: Density Classwork

Front

What is density?

Back

Density is the mass of an object divided by its volume, typically expressed in kilograms per cubic meter (kg/m³).

Front

How do you calculate the volume of an object given its mass and density?

Back

Volume = Mass / Density.

Front

What is the formula for density?

Back

Density (ρ) = Mass (m) / Volume (V).

Front

What unit is density commonly measured in?

Back

Density is commonly measured in kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³).

Front

If an object has a density less than that of water, what will it do in water?

Back

It will float.

Front

If an object has a density greater than that of water, what will it do in water?

Back

It will sink.

Front

What is the density of gold?

Back

The density of gold is approximately 19,320 kg/m³.

Front

What is the density of silver?

Back

The density of silver is approximately 10,490 kg/m³.

Front

How can you determine if an object will float or sink in a liquid?

Back

Compare the object's density to the density of the liquid; if the object's density is less, it will float; if more, it will sink.

Front

What is the density of mercury?

Back

The density of mercury is approximately 13,534 kg/m³.
