PHYSICS Flashcards
Standard quantity used to express a physical quantity
Measurements unit
Represent a number as a factor multiplied by a power of 10
Standard scientific notation
Shorthand for writing very large or small numbers
Scientific notation
Refers to the closeness of the given set of value to the correct values
Accuracy
Refers to the difference between the calculated value and actual value
Error
Refers to the closeness of the values to each other nearer more precise
Precision
usually described as an error in measurement
Uncertainty
Factors why errors occur
Device use/instrumental error
Methods/procedural
Condition made/environmental error
Human error
Unsystematic error
No pattern, inconsistent
Random error
Consistent, repeatable error due to measuring device
Systematic error
Agreement of several measurements made in the same way
Precision
Motion of any object can be described by words and phrases
Vector and scalar
Physical quantity that has magnitude
Scalar
Physical quantity that has both magnitude and direction
Vector
Study of mathematical description of motion
