IB Physics HL Question and answers rated A+ IB Physics HL Fundamental SI units - correct answer kilogram (kg), metre (m), second (s), ampere (amp), mole (mol), kelvin (K) Random error - correct answer An unpredictable and largely uncontrollable uncertainty. (Examples include human reaction time and other forms of human measurement.) (Random errors can be reduced by taking the average of repeated measurements.) Systematic error - correct answer An error that occurs on all measurem...

1.1 Introduction There are two ways to motivate the notion of a vector: one is by means of lists of numbers and subscripts, and the other is by means of certain objects in physics. We discuss these two ways below. Here we assume the reader is familiar with the elementary properties of the field of real numbers, denoted by R. On the other hand, we will review properties of the field of complex numbers, denoted by C. In the context of vectors, the elements of our number fields are called scal...
