Matter, Mass, Weight, Volume, and Density

Vocabulary practice flashcards covering definitions, formulas, relationships, and problem-solving concepts for matter, mass, weight, volume, and density.

Matter

Anything that has mass and takes up space.

Mass

A measure of the amount of matter in an object.

Weight

A measure of the gravitational force exerted on an object.

Volume

The amount of space that an object takes up, or occupies.

Density

The ratio of the mass of a substance to the volume of the substance.

Gravity

The force exerted on an object that determines its weight and causes weight to vary based on location in the universe.

Space

The physical area or volume that an object occupies.

Location-dependent weight

The principle that an object's weight can change depending on where it is located in the universe due to differences in gravity.

Mass invariance

The property that an object's mass remains the same regardless of whether it is on Earth or on the Moon.

Gravitational differences

The variations in gravitational pull between celestial bodies, such as the Earth and the Moon, which cause an object's weight to change while mass remains constant.

Density formula

The mathematical formula $D = \frac{m}{v}$, which expresses density as mass divided by volume.

Volume formula

The mathematical formula $v = \frac{m}{D}$, which calculates volume by dividing mass by density.

Mass formula

The mathematical formula $m = D \times v$, which calculates mass by multiplying density by volume.

Mass/Volume

The mathematical ratio of mass to volume used to express density.

Mass/Density

The ratio used to calculate volume by dividing mass by density.

Finding Mass

The operation performed when density and volume are known, requiring density to be multiplied by volume.

Finding Volume

The operation performed when mass and density are known, requiring mass to be divided by density.

Density calculation of a liquid ($50\,\text{g}$, $10\,\text{mL}$)

The process of using the formula $D = \frac{m}{v}$ to find the density of a liquid with a mass of $50\,\text{g}$ and a volume of $10\,\text{mL}$.

Mass calculation ($2\,\text{g/cm}^3$, $5\,\text{cm}^3$)

The application of the formula $m = D \times v$ to determine the mass of an object with a density of $2\,\text{g/cm}^3$ and a volume of $5\,\text{cm}^3$.

Volume of a $100\,\text{g}$ block with density $5\,\text{g/cm}^3$

A calculation using the formula $v = \frac{m}{D}$ that results in $20\,\text{cm}^3$ of space occupied.

Density of a metal block ($30\,\text{g}$, $6\,\text{cm}^3$)

A value determined by dividing a mass of $30\,\text{g}$ by a volume of $6\,\text{cm}^3$ using the formula $D = \frac{m}{v}$.

Mass of a $0.8\,\text{g/mL}$ substance with $25\,\text{mL}$ volume

A total mass calculated as $20\,\text{g}$ using the formula $m = D \times v$.

Volume of a $120\,\text{g}$ sample with density $3\,\text{g/mL}$

A volume calculation found by dividing the mass of $120\,\text{g}$ by the density of $3\,\text{g/mL}$ using $v = \frac{m}{D}$.

Gram ($\text{g}$)

A metric unit used to measure the mass of an object or substance.

Milliliter ($\text{mL}$)

A metric unit used to measure the volume of liquids and samples.

Cubic centimeter ($\text{cm}^3$)

A unit of volume used to quantify the space occupied by solid objects such as blocks.

Grams per milliliter ($\text{g/mL}$)

A unit of density representing mass in grams per unit volume in milliliters.

Grams per cubic centimeter ($\text{g/cm}^3$)

A unit of density representing mass in grams per unit volume in cubic centimeters.

Measure of occupied space

Volume, which specifically measures how much space an object occupies.

Measure of matter

Mass, which quantifies the exact amount of matter contained within an object.
