Class Vocabulary
Term
Definition
area
A measurement of the amount of space contained within a flat, enclosed shape.
base unit
A unit of measurement that can be determined by taking one measurement without having to combine any other measurement. Length, mass, and temperature are examples of base units.
CNC lathe
A lathe that is controlled by a computer running programs driven by numerical data.
derived unit
A unit of measurement that is determined by combining one or more measurements. Miles per hour or kilometers per hour are examples of derived units.
diameter
The distance from one end of the circle to the opposite end through the center.
digital caliper
A measuring instrument typically used in inspection that contains two pairs of jaws on one end and a long beam containing a marked scale of unit divisions. Digital calipers display measurements in both English and Metric units.
English system
A standard system of measurements based on the inch, pound, and Fahrenheit degrees. English measurements are primarily used in the United States and England.
International System of Units
Another name used for the Metric System. International System of Units is often abbreviated as SI.
kilometers per hour
A derived unit that indicates speed, or how many kilometers an object travels in one hour. Kilometers per hour is calculated by dividing the distance traveled by the time elapsed.
length
A measurement of distance from one point to another.
mass
A measurement of the heaviness of an object. Mass is usually expressed in Metric units. In the shop, weight and mass are used interchangeably.
measurement
The act or process of measuring an object. We use units of measurement daily.
Metric system
A standard system of measurements based on the meter, kilogram, and Celsius degrees. The metric system is internationally recognized.
miles per hour
A derived unit that indicates speed, or how many miles an object travels in one hour. Mph is calculated by dividing the distance traveled by the time elapsed.
prefix
A word attached to the beginning of another word. Prefixes are attached to the beginning of a base unit of a Metric measurement to indicate the specific power of ten.
pressure
The amount of force applied upon an object. Pressure is a derived unit that combines time, area, and mass.
rectangle
A shape with four angles and four sides forming 90° angles.
speed
The rate at which an object travels. Speed is calculated by dividing the distance traveled by the time elapsed.
square
A shape with four equal angles and four equal sides.
temperature
A measurement of the hotness or coldness of an object.
volume
A measurement of the amount of space contained within a three-dimensional shape.
weight
A measurement of the gravitational pull on an object on the earth's surface. Weight is expressed in English units. In the shop, weight and mass are used interchangeably.
