Air Track - Direct Measurement Of Acceleration
To measure acceleration using two different procedures.
Air track, gliders, two photocell gate timers, small accelerating masses with audiotape frictionless cord, as photographed.◙
All gliders are equipped with a 5 cm tab which interrupts the light beam when passing through the photocell gate. The timing system can be set to measure the time a tab takes to move through the gate or the time taken for the glider to move from gate A to gate B (not B to A). The timer can be set at full scale ranges from 99.9 ms through 999 seconds for a range of applications. One timer is set so that it records the time for a glider to move from A to B. The second timer is set to measure the time the tab requires to move through gate A, and then after resetting, the time required for the ta
