-The simplest model of motion is for an object that moves in a straight line at constant speed. You can use this simple model to build your understanding about the basic ideas of motion, and the different ways in which you will represent that motion. At the end of these notes, you will find the position update formula, which is a useful tool for predicting motion (particularly, when it comes to constant velocity motion).+The simplest model of motion is for an object that moves in a straight line at constant speed.

 The displacement vector ($\Delta \vec{r}$) describes the change of an object's position in space (i.e., a change in location). So, you can think of the displacement vector as //displacement = change in position = final location - initial location//. This change in position is represented in the diagram to the right. Mathematically, we represent the displacement like this: The displacement vector ($\Delta \vec{r}$) describes the change of an object's position in space (i.e., a change in location).
