Cory Miller In this lab we look at the terms position, distance, and displacement. The position of an object is defined as a straight-line distance and direction of the object from a chosen reference point. The distance traveled by an object is the length of the path traveled by the object from position 1 to positon 2. The displacement of an object is defined as the straight-line distance and direction that the object moved when going from one position to another position.

One of us will take three constant speed walks along a measured path: two walks away from the referenct point - one slow walk, then one fast walk and one walk toward the reference point. During the walk, the rest of the class measured how long it takes our walker to reach each of the positions given in the chart below. We'll start timing when the walker gets to the 3 meter mark. We recorded the class data in a table for each walk.
