kinematics the study of how motion occurs without consideration to why it occurs scalars quantities, such as temperature or distance, that are just numbers without any direction vectors quantities that have both a magnitude and a direction distance total length displacement net length average velocity displacement/change in t average speed distance/duration of time negative slope on position vs time graph object goes backwards posit...

IB Physics HL 2023 Update Fundamental SI units - ANS-kilogram (kg), metre (m), second (s), ampere (amp), mole (mol), kelvin (K) Random error - ANS-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 - ANS-An error that occurs on all measurements. (An example is a zero error on a scale.) (Systematic errors can ...

Augmented matrix Correct Answer a+b=c d+e=f [ a b c ; d e f] Row echelon form (REF) Correct Answer 1. All nonzero rows are above any rows of all zeros, called 0-rows 2. Each leading entry (leftmost nonzero entry) of a row is in a column to the right of the leading entry of the row above it 3. All entires in a column below a leading entry are zero Reduced row echelon form Correct Answer All the rules for row echelon for plus... 1. The leading entry in each nonzero row is 1 2. Each lea...
