Experiment P01: Understanding Motion I - Distance and Time (Motion Sensor) Concept: linear motion Time: 30 m SW Interface: 500 & 700 Macintosh(r) file: P01 Understanding Motion 1 Windows(r) file: P01_MOT1.SWS EQUIPMENT NEEDED • Science Workshop(tm) Interface • base and support rod • motion sensor PURPOSE The purpose of this activity is to introduce the relationships between the motion of an object - YOU - and a Graph of position and time for the moving object. NOTE: This activity is easier to do if you have a partner to run the computer while you move. THEORY When describing the motion of an object, knowing where it is relative to a reference point, how fast and in what direction it is moving, and how it is accelerating (changing its rate of motion) is essential. A sonar ranging device such as the Motion Sensor uses pulses of ultrasound that reflect from an object to determine the position of the object. As the object moves, the change in its...
