Abstract
There are several ways in the literature to determine the value of gravitational acceleration. we will present a way that allows us to determine the we used an audio plug (3.5-mm jack) that can be reused from types of plugs can also be purchased and are very cheap. In this article, a computer speaker or microphone that are damaged. These value of gravitational acceleration very accurately using every-day materials. For this, we will use an electromagnet, a coil, a steel sphere, a speaker, an audio cable (3.5-mm jack), a direct current power supply, connecting wires, a computer, and the Audacity software.
