Simple Harmonic Motion: Using a spring with a Force and Motion sensor
Minimum 17 cm
Weigh both the spring and the suspended mass (added together they are the oscillating mass).
Make sure that the apparatus is as rigid as possible, if necessary use clamps to secure the base.
When the mass is stationary it should be about 50 cm from the Motion sensor.
Connect the Motion and Force sensor to the EasySense data logger. The range of the Motion sensor should be set to Distance.
Open the EasySense program and select Graph. From the wizard select the following: Time
Interval
5 seconds
20 ms
Select Test Mode and ensure that the Motion sensor will detect the mass throughout its travel.
With the mass hanging stationary on the spring, zero the Force sensor.
Using amplitude of about 15 – 25 cm, pull the spring downwards and set it oscillating. Check that it is oscillating vertically.
Select the Start icon to begin logging.
