An air track glider is accelerated up an inclined track by the string, pulley and mass system. A bluetooth Wireless Dynamic sensor can be used to track force before and after the mass is released, acceleration as well as the time of the event.
Notes: 100 g mass works well. For cleaner data collection, stop recording before the mass hits the floor or cart hits the edge of the track.
Location: Wireless Dynamic Sensor L5-3, Mass FG-7, Blocks H1-5, Airtrack D2-1
