The Visual Accelerometer provides acceleration data and visual clues that allow students to better understand the concept of acceleration. The sensor features 10 high output, wide-angle LEDs that indicate the magnitude and direction of acceleration. The case of the sensor fits directly into a dynamics cart, and features ties for pendulum motion and a pass-through so the sensor can be thrown vertically along a rope.
The Visual Accelerometer features three fixed ranges, an auto-scale and a peak-hold option. The peak-hold mode stores the maximum acceleration experienced by the sensor after a countdown appears on the LEDs. The zero button on the sensor negates the effect of changing the orientation of the sensor.
The Visual Accelerometer can also be used in stand-alone mode. While away from the computer, the LEDs give students a meaningful, visual measurement of acceleration.
