6. Applications
Measuring the position, velocity and acceleration of
moving bodies using multiple photo gates.
7. Sample experiment
Measuring the velocity of a body on an air track
Apparatus needed:
TM
1 3B NETlog
1 Digital input box
2 Photo gates
1 Air track, 1.6 m
1 Set of 4 velocity flags
1 Air flow generator (230 V, 50/60 Hz)
or
1 Air flow generator (115 V, 50/60 Hz)
2 Stand base, 1 kg
2 Stand rods, 100 mm
2 Universal clamps
•
Assemble stands by inserting stand rods into
two bases and attach the two photo gates to
them at the desired positions on the air track
(Fig. 1).

TM
On the 3B NETlog
mode, and in the software of the 3B NETlab
select the experiment template for measuring
the velocity of a glider on the air track. The
software contains all the necessary instructions
for setting up the calculation.
•
Carry out the experiment and evaluate the
result.
