Document Summary
End effector: most distal segment which performs the task. Rectilinear path better for velocity (longer path sacrificing accuracy) Measures displacement with respect to a given point. Eg. locate a joint in space (x, y, z) Quantify the motion of the hip joint etc. The shortest distance between the initial position and the final position. Actual distance covered by a moving body irrespective of the direction moved in. Scalar has magnitude but no direction. * adding vector quantities needs to consider direction = gives a vector quantity as result. When object gets faster or slower, changes direction. Can add variables of the same units (scalars) Consider direction when adding vectors (2km north + 3km south = 1km south)
