Add to FacebookOur school recently acquired1 Vernier's Wireless Dynamics Sensor System (WDSS). The WDSS consists of a three-axis accelerometer, altimeter, and force sensor that has the ability to remotely collect data for later transfer to a computer.2 While our primary purpose for acquiring the WDSS was to enhance our amusement park physics experiments, we decided to test one of the WDSS units by using it to collect data during the drive home from school one day, since measuring the acceleration of a car is one of the experiments suggested in the Vernier Wireless Dynamics Sensor System User Manual. We taped the device to the floor of the car with its +x-axis pointed forward and its +y-axis pointed to the left. The WDSS was configured to take five samples per second for a total time period of 10 minutes.
