Forced Oscillator

A forced oscillator is a system that vibrates or oscillates because it is being repeatedly driven by an external force at a certain frequency. Imagine pushing someone on a swing; if you push at just the right times, the swing goes higher. This "right timing" is called resonance. The system absorbs energy from the external force, resulting in larger oscillations if the force matches the system's natural frequency. Forced oscillators are common in engineering and physics, seen in devices like clocks, bridges, and electronic circuits, where external influences control or influence their vibrations.
