Damping in Oscillations

When a system oscillates, it often encounters resistive forces like friction or air resistance.
These forces cause the system to lose energy over time, reducing the amplitude of oscillations.
This process is called damping.
Damping is the gradual reduction in the amplitude of an oscillating system due to energy losses caused by resistive forces such as friction or air resistance.
Damping can be categorized into three types:
1. Light damping.
2. Critical damping.
3. Heavy damping.
Each type affects the system's behavior differently.

Light Damping: Gradual Reduction in Amplitude

Definition

Light damping

Light damping is when the amplitude of each oscillation is fractionally less than the previous one

In light damping, the amplitude of oscillations decreases slowly over time.
The system continues to oscillate, but each cycle has a slightly smaller amplitude than the previous one.

Note

The amplitude decreases exponentially, meaning it reduces by a fixed percentage over equal time intervals.
