Document Summary
Use third law: law of reaction (3rd law): push or pull something, it pushes or pulls back, how can we push or pull something, changing our shape/skeleton (push by straightening extremities, etc. ) Articulation/segmentation: a whole body can be articulated into multiple segments, articulation: to divide into parts, segment: to cut, articulation or segmentation of a body permits relative movement between segments. Joining/linking articulated segments: many segments of a complex articulated body are typically linked/joined to each other, points/mechanisms of linkage can be called links or joins , when segments are joined, their relative motion is constrained. Segmental vs joint position: the angular position of a segment (bone) is measured relative to the ground (go ccw, the position of a joint is the angle between segments. Joint coordinate systems: gas and las are fine in a lab, but useless in a gym or clinic.
