Measurement and Error Concepts

Front

how close the measurement is to the correct value

Back

Accuracy

Front

how close the experiment is to one another

Back

Precision

Front

occurs when there are variations in the environment or in the measurement techniques

Back

Random Error

Front

tend to be consistent in magnitude and directions and is sometimes caused by faulty device/equipment

Back

Systematic Error

Front

a quantitative measure of how much your measured values deviate

Back

Uncertainty

Front

any quantity that has magnitude and no direction

Back

Scalar

Front

any quantity with magnitude and direction

Back

Vector

Front

the single vector of the two component vectors perpendicular to each other

Back

Resultant Vector/Resultant Force

Front

the process of finding the magnitude of the component vectors in a certain direction.
