From g-Force to V-Force
The high school student is safely strapped into the seat of the amusement park roller coaster. She selects the “Roller Coaster” mode in the Physics Toolbox Sensor Suite app, secures her smart phone in her pocket, and enjoys the ride as the car climbs slowly over the waiting crowd below, pauses dramatically at the top of the track, and then plunges downward. After the laughter subsides and her heart returns to its normal rate, the student checks her phone. The app has employed its various sensors to measure, collect, display, and record data, such as g-force.
