Online. Segment (kinematics) Page Published on Wednesday, June 18, 1997 by Gideon Ariel Segment (kinematics) A segment is a vector defined by two points. Note that a segment has a direction. If points A and B are switched, the segment points in the opposite direction. This is important when specifying angles between them (see clues). Examples: Segment Point A "From" Point B "To" Right upper arm Right shoulder Right elbow Right lower arm Right elbow Right wrist See also AnalysisDefinition of an APAS/Wizard analysisClueDefinition of an APAS/Wizard clueElementElement types (in documents, tree views and list views)EventDefinition of an eventKinematicsDefinition of an APAS/Wizard kinematics elementPoint (kinematics)Definition of a point (kinematics)Segment (kinematics)Definition of a segment (kinematics)Vector typesDefinition of vectors types used in APAS/WizardViewDefinition of a viewWizardDefinitions in APAS/Wizard Reference: /wizard/manual/concepts/wizard.segment.html
