TermDefinition
Diameter A chord that passes through the center of a circle; the length of a straight line segment that begins on a circle, passes through the center, and ends on the circle. > The length of a diameter is twice the length of a radius of the circle.
Kilogram (kg) The SI unit of mass equal to 1,000 grams.
Mass The resistance that an object offers to a force acting upon it; the ratio of the net force acting on the object to its acceleration: m=F/a. >The SI unit of mass is the kilogram(kg).
Meter(m) The SI unit of length. It is a fundamental unit.
Order of Magnitude A rough measure of size relationships, usually expressed as powers of 10. > For example, a quantity may be approximately ten times (1 order of magnitude), or a hundred times (2 orders of magnitude), or a thousand times (3 orders of magnitude)
Second The SI unit of time. It is a fundamental unit.
Circumference The perimeter or "distance" around a circle. Mathematically determined as the product of π and the diameter, or the product of π and twice the radius: C= πd = 2πr.
Slope of a Graph The ratio of the change in the vertical coordinate to the change in the horizontal coordinate. In the xy- coordinate plane, the slope is Δy/Δx. The slope of a displacement versus time graph is velocity. The slope of a velocity versus time graph is a.
Magnitude The size of a vector quantity, ignoring its direction.
Kilometer(km) 1,000 meters.
Centimeter(cm) 1/100 or 0.01 or 10^-2 meter.
Derived Unit A unit of measurement that can be expressed in terms of the fundamental international standard (SI).
Micrometer ( μm) One-millionth or 0.000001 or 10^-6 meter.
Nanometer (nm) One-billionth or 0.000000001 or 10^-9 meter.
Millimeter (mm) 1/1000 or 0.001 or 10^-3 meter.
Decimeter (dm) 1/10 or 0.1 or 10^-1 meter.
