Mass-Spring system

We shall take as working example the experiment springFree.exp.

Basic data

The basic data for this experiment, in adequate units, are:

Measurement of the free Period

We start from a given amplitude, with zero velocity, and allow for 10 full oscillations (checking the sign change in velocity after the 10th oscillation)

This results in

Checking the results:

The theoretical value for the period is 2*p*sqrt(m/k):

T = 2*p*sqrt(m/k) = 0.2*p = 0.6283


Change the parameters of the system and observe the results. For instance, change the mass and, for a different experiment, change the spring constant. Measure for each case the period and check with the theoretical computations.
