PHTY103 Lecture Notes - Lecture 2: Kinematics, Resultant Force, Exercise Prescription
Document Summary
Week 2: applied biomechanics podcast: differentiate static and dynamic situations, define basic biomechanical terminology. Bio/mechanics: the application of mechanical principles to living organisms. Mechanics: branch of physics that analyses the actions of forces on particles and mechanical systems: distinguish between qualitative and quantitative approached for analysing human movement. Qualitative: non-numeric evaluation of motion based on direct observation. E. g. step 1 is shorter than step two. Quantitative: numeric evaluation of motion based on data collected during the movement. E. g. the distance of step one is 13cm and the distance of step two is 23cm: differentiate kinematics and kinetics, describe forces and moments. Kinematics and kinetics- biomechanical analysis can be conducted from two perspectives. Concerned with characteristics of motion from a spatial and temporal perspective. (change in place, position, or posture occurring over time and relative to some point in the environment). Examines the forces acting on a system, such as the human body.
