Metric Conversions, Mass, Volume, Gravity, and Density Vocabulary

Vocabulary flashcards covering metric conversions, volume, mass, weight, gravity, and density principles.

Meter

A metric base unit used to measure distance.

Prefix/Unit

A base measurement such as grams, liters, and meters.

Conversion of cm3 and ml

1 cm3 = 1ml

Liter

A metric base unit used to measure volume.

Gram

A metric base unit used to measure mass.

KUCMN

The phrase used to recall Kilo, Unit, Centi, Milli, Nano

Metric Staircase

A conversion model where each step represents $1$ decimal place movement; moving down/right shifts the decimal right, and moving up/left shifts the decimal left.

Volume

The amount of 3D space an object takes up. NOT area measured in cm3 or ml.

Volume of Regular Shaped Solids

The volume calculated using the mathematical formula $\text{Length} \times \text{Width} \times \text{Height}$. Use cm3

Liquid Volume

Measure using a beaker. Measure from the bottom bend of the liquid, use liters or milliliters.

Massive defention

MASSive talks about MASS instead off volume so one small box is of metal is MORE massive that an huge cardbroad box filled with cotton.

Density labels

G/cm3, g/ml, and kg/m3.

Water Displacement

A method to measure the volume of an irregular solid by recording the initial water volume, dropping the object into the liquid, and finding the difference from the final volume.

Milliliter to Cubic Centimeter Conversion

The metric equality conversion factor where $1mL=1cm^3$ .

Mass

The amount of matter (stuff) in an object, measured in grams ($g$) or kilograms ($kg$) using a scale or triple beam balance.

Weight

The force of gravity acting on an object's mass, which changes based upon where you are in space.

Gravity

A force of attraction between any two objects with mass that depends on the mass of the objects and the distance between them.

Universal Law of Gravitation Formula

The formula $F_g = G \frac{m_1 m_2}{r^2}$, where $F_g$ is gravitational force, $G$ is the gravitational constant ($6.674 \times 10^{-11} m^3 kg^{-1} s^{-2}$), $m_1$ and $m_2$ are masses, and $r$ is distance between center points.

Earth vs Moon Weight Comparison

An illustration of how gravity affects weight while mass stays constant; an astronaut weighing $200 \text{ lbs}$ ($90 kg$) on Earth weighs $33.2 \text{ lbs}$ ($15 kg$) on the Moon.

Mass vs Weight Comparison

Mass measures the amount of matter and is same everywhere in space, whereas weight measures force of gravity on mass and differs by celestial location.

Density

The amount of matter in a given space, representing the mathematical relationship between mass and volume ($\text{Density} = \frac{\text{Mass}}{\text{Volume}}$). Aka, the compactness of an object.

Density Triangle

A visual formula guide showing the relationships $D = \frac{M}{V}$, $V = \frac{M}{D}$, and $M = D \times V$.

Density of Pure Substances

The principle that the density of a pure substance is ALWAYS the same throughout regardless of object size (e.g., diamond density is always $3.2 g/cm^3$).

Density of Water

Liquid water reaches its maximum density of $1.0 g/mL$ (or $1.0 g/cm^3$) at $4^\circ C$.

Thermal Effect on Density

An increase in temperature increases volume and decreases density, while a decrease in temperature decreases volume and increases density.

Pressure Effect on Density

An increase in pressure decreases volume and increases density, while a decrease in pressure increases volume and decreases density.

High density material …. And Low density material ….

Sink and float
