We present four experiments (spring, pendulum, free fall, and parabolic throw) for measuring the acceleration due to gravity g, using a computer sound card. In each case, a device is connected to the audio input and an audio editing software [1] is used for recording the electric signal generated by the device. This method allows time measurements with an accuracy of about 10-4 s.
These experiments are enriched with other physical phenomena that contribute to learning with the support of new technologies.
