Abstract:
The study of oscillatory motion is one of the essential topics in physics, because it allows understanding the application of the fundamental laws of classical mechanics to simple physical systems and it can be used, by analogy, in the study of electrical circuits, powered by alternating voltages. In this paper we explain the use of GeoGebra software in the study of oscillatory motion, starting from the simple ideal system, the harmonic linear oscillator, in order to subsequently include some more complicated effects related to the damping oscillations (that are encountered in real-life systems). Damped oscillations are usually treated with a resistance force, which is proportional to the velocity. This approach has the advantage of a relatively simple mathematical solution, yet, in some situations, it is preferable to take into account the constant frictional force between the body and the surface on which it moves. Simulations created in GeoGebra have the advantage to operate on any desktop browser. All that is left is to understand the mathematics behind the physics. By developing and employing simulations, the students have the opportunity to make important connections between their Math and Physical Science knowledge, further developing their skills in solving interdisciplinary problems.
