Document Summary

Human body is meant to translate and rotate. Linear movement comes as a result of angular movement. To move any part of the body in a straight line you must use at least two segments. Ex:// curling, need to open knee elbow wrist, in order to do this you need to move two segments. Clockwise= negative rotation right hand thumb rule. 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 in its initial position and its final position with the direction of rotation. Angle relative to horizontal, segment to a predefined line. Relative to another line, forearm relative to the upper arm. Average and instantaneous values may be determined. Can be as specific or as general as we want it to be. Change of angular velocity/ change in time a= delta w/ deltat (rad/s^2)
