5. Operation
•
Place the sensor box alongside the experiment
and attach the acceleration sensor (small black
box) to the mass to be investigated (target). Use
the supplied Velcro strip or a clamp for this
purpose.
•
Read the value of the acceleration from the
display on the 3B NETlog
6. Applications
Demonstration track and air track experiments:
Downward acceleration
Elastic and non-elastic impact
Oscillating spring-mass system
High-resolution measurement of objects' inclina-
tion
Pendulum oscillations
Jumping experiments; "bungee jumping"

Run the 3B NETlab
priate template for the experiment using the
5g accelerometer.
•
Attach the acceleration sensor to the weight
with a piece of Velcro.
•
Suspend the weight and acceleration sensor
from the eye at the bottom of the coil spring
and be careful not to hinder the oscillating
motion.
•
Drape the connecting lead for the acceleration
sensor over the universal clamp, as shown in
Fig. 1. This adds further to the damping.
•
Pull down the weight by hand to the level of
the stand base and release it.
•
Start recording the measurement data in 3B
TM
NETlab
(Fig. 2).
•
Analyse the recorded chart.
