Damped Oscillation with Cobra DigiMotion

Damped oscillation describes a realistic motion of a pendulum in which energy losses due to friction and air resistance are taken into account. As a result, the amplitude of the pendulum decreases over time until the system eventually comes to rest. With the MotionBoard, oscillations can be recorded precisely, allowing the decay of amplitude and damping parameters to be determined experimentally.

Students should recognize that oscillations are damped by friction and air resistance and that the amplitude decreases over time. They learn to determine damping parameters experimentally, understand the influence of damping elements on the oscillation period, and analyze the decrease in amplitude using diagrams. In doing so, they practice the quantitative analysis of oscillations and the application of mathematical descriptions of damped motion.
