Kilogram:Standard of mass; mass of particular cylinder of platinum- iridium alloy
Vector Quantity: it has both a magnitude and a direction in space
Fractional Error: it is also known as percent error
Parallel: vectors that have the same direction
Operational Definition: we can define them only by describing how to measure them
Accuracy: it is defined as how close it is likely to be to the true value
Physical Quantity: any number that is used to described a physical phenomenon quantitatively
Meter: it is defined as the distance that light travels in a vacuum in 1/299,792,458 second
Second: defined as time required for 9, 192, 631, 770 cycles of this microwave radiation
Components: this is called the two numbers Ax and Ay
Cross
International System: the abbreviation for its French name, Systéme International
Direction: it is required in unit vectors
Unit:standard defines a _____ of the quantity
Vector Sum: it is also known as the resultant
Cross: vector product is also known as _____ product
Prefix:it is added to the name of the fundamental unit
Precision:it is not the same with accuracy
Dot:scalar product is also known as _____ product
Velocity:_______ is the speed of an object and a specification of its direction of motion
Scalar:_____ is a quantity which can be described by a single number, unlike vectors
