Damped oscillation refers to the gradual reduction in amplitude of an oscillating system over time due to energy loss. This energy loss can occur through various mechanisms, such as friction or air resistance, which convert the system's mechanical energy into heat. As a result, the oscillations become less pronounced until they eventually stop. Common examples of damped oscillation include a swinging pendulum that slows down or a vibrating guitar string that loses its sound. In physics, damped oscillations are often described using mathematical models, such as those involving harmonic motion and differential equations, to analyze the behavior of the system.
