Key Concepts

Damped Oscillator

A damped oscillator is a system in which an additional force, typically proportional to the velocity, opposes the motion. This damping force leads to energy loss over time, causing the amplitude of the oscillation to decrease. The presence of damping not only affects how quickly the oscillations die out but also influences the effective oscillation frequency of the system.

Natural Frequency

The natural frequency of an oscillator is the frequency at which a system oscillates when there is no damping or external driving forces present. It is determined solely by the system's physical properties such as mass and stiffness. In an undamped system, this frequency represents the inherent rate of oscillation.

Effect of Damping on Frequency

When damping is introduced, the oscillation frequency decreases compared to the natural frequency. This reduction occurs because the damping force alters the balance between the restorative force and the inertial force, effectively slowing down the oscillatory motion. Mathematically, the damped frequency is derived by modifying the natural frequency by a factor depending on the damping ratio, usually resulting in a lower frequency than in the ideal, undamped system.
