Document Summary
Physiological detection of acceleration: motion is a change of position with time. These images of a bird in flight show the bird"s position as a function of time. Motion: in any motion, we deal with: How far has the object moved from where is was: displacement. How fast is the motion: velocity. Is the motion getting faster or slower: acceleration. Refers to an object location relative to some origin or reference point. 4 x1 x2: the position of the ball is different in these two. An object location relative to some origin or reference point, shown as a vector. x(cid:71) One-dimensional motion: vector and scalar quantity, vector: is a quantity that has both a magnitude and a direction. Position is a vector quantity: scalar: is a quantity with no direction. The mass of an object is a scalar quantity. Refers to the change in an object"s position (cid:71) x (cid:32)(cid:39) (cid:71) x (cid:16) f (cid:71) x i.
