1 | Measurement | | _____ | A ____________ quantity is one that’s a combination of several fundamental quantities. Examples of derived quantities include area, volume, density, force, pressure, speed, work and power. |
2 | Quantity | | _____ | any measurable parameter that describes a particular physical attribute. Examples of quantities include mass, length, area, speed, elapsed time, and energy. |
3 | Standard | | _____ | the absence of any motion |
4 | Accuracy | | _____ | the specific standard to which a given measurement is being compared |
5 | Precision | | _____ | continuous change of position of an object relative to its surroundings, which are assumed to be fixed or stationary. |
6 | Resolution | | _____ | a ____________ condition for a particular outcome to occur is one that guarantees that the event will occur as long as the condition is present. |
7 | Necessary Condition | | _____ | the __________ of an instrument refers to the least amount of change that can occur in a quantity and still be detected and reported by the instrument as a discreet value. It’s also a measure of how well an instrument can discriminate between two values that lie very close to one another. |
8 | Sufficient Condition | | _____ | Modern _______ systems are based on universally recognized standards. The current international standard _________ system is the International System of Units (SI system). The SI system is a special _______ system. |
9 | Motion | | _____ | the __________ of a measurement process refers to the reproducibility of the process. It refers to the amount of consistency among repeated measurements under the same conditions. |
10 | Rest | | _____ | the ratio of the size of the quantity being measured to the size of the standard being used. |
11 | point Object | | _____ | idealized representation of a real object that has no structure or dimensions and behaves as though it’s a mathematical point. |
12 | Artifact | | _____ | A ___________ quantity is one that can’t be broken down into more simple terms. Physics has only three fundamental quantities: (1) length, (2) mass, and (3) time. |
13 | Property | | _____ | units based on the dimensions of the human ex) foot, mile, cubit, hand, and span |
14 | Magnitude | | _____ | how closely the result of a particular measurement agrees with the actual magnitude of the quantity being measured. |
15 | Unit | | _____ | a recognized physical artifact or property to which all measurements of a particular quantity are compared |
16 | Traditional Systems | | _____ | The __________ measurement system is based on values found in _______. Examples include the light-year, astronomical unit, the lunar cycle, the solar day, etc. |
17 | Natural Systems | | _____ | the comparison of an unknown quantity to a recognized standard by means of a calibrated instrument or device in order to determine the magnitude of the quantity. |
18 | Metric Systems | | _____ | a ____________ condition for a particular outcome to occur is one that is absolutely essential. Removal of the necessary condition makes it impossible for the specific outcome to occur. |
19 | fundamental quantities | | _____ | any object that is used as a standard for measurement |
20 | derived quantities | | _____ | a condition used as a standard for measurement ex) boiling point of water |
