Motion In One Dimension

     Left or right.  Up or down.  In or out.  North or south.  When we talk about objects moving in one dimension, we simply mean that the motion of the object is along one coordinate axis, usually either the traditional x- axis (horizontal motion) or the y-axis (vertical motion).  In this unit, we will study objects moving in the positive and/or negative direction along one spatial axis at a time.  We'll start with the very basics of position and work our way through a series of steps and equations to learn how we describe motion and changes to that motion.
