Motion Diagrams - Directions

Using the Motion Diagrams Concept Builder is quite simple. You will be presented with a verbal description of an object's motion and you will have to use on-screen controls to create a motion diagram for that motion. First you will select the dots from a choice of three - pay careful attention to the spacing between dots and the manner in which that spacing changes (or remains constant). Read the dots from left to right for a rightward motion and from right to left for a leftward motion. Second, you will have to pick the vectors - either velocity, acceleration, or both - from among a choice of six. Give attention to the direction that the vectors point - right or left - and whether they becom shorter, longer, or remain the same length. Once you tap on a set of vectors, they are superimposed on your dot diagram. If you like the look of the vectors, tap on the Select These Vectors button.
