Volume, Density, Dimensional Analysis & Prefixes (Video Notes)

Vocabulary flashcards covering volume concepts (liters and cubic units), velocity, density, dimensional analysis, unit conversions, and SI prefixes.

Volume

The amount of space an object occupies; can be expressed in liters for liquids or in cubic length units for solids.

Liter

A unit of volume used to measure liquids.

Cubic length unit

A unit of volume expressed as a length cubed, used for solids (e.g., m^3).

Velocity

The rate at which distance changes with time; the relationship between time and distance.

Density

Mass per unit volume.

Dimensional analysis

A method to organize and perform unit conversions by multiplying by conversion factors.

Dozen

A unit equal to 12 items; 3 dozen equals 36.

Conversion factor

A ratio used to convert from one unit to another in dimensional analysis.

Prefix
