Document Summary

Displacement (vector) change in position between two time stamps. Human body meant to translate and rotate least two segments. To move any part of the body in a straight line you must use at. When a segment rotates counter clockwise = positive rotation. Clockwise = negative rotation right hand thumb rule. 2 necessary segments in changing of angles that take place. You are wrapping your right hand around the axis of rotation. Rotation is measured by an angular displacement. Angular position = orientation of a line relative to some other line or plane. Angular displacement = the angle between a line segment and its initial position and its final position with direction of rotation. If lines are moving relative to each other that is displacement. If you displace angularly, you are taking two straight lines that intersect each other and closing them (making the angle smaller) Absolute relative to some sort of axis,
