Sphero fans all the way from Ireland explore terminal velocity by building parachutes! This program uses the accelerometer in Sphero and a timer to record the start and stop of your parachute’s freefall. After you drop your ’chute from a certain height, the program calculates the average airspeed in centimeters per second. Depending on the air resistance and weight of the parachute holding your Sphero, the airspeed will vary. It’s physics!
