WebThe oscillation caused to a body by the impact of any external force is called Forced Oscillation. Forced oscillation can be defined as an oscillation in a boy or a system occurring due to a periodic force acting on or driving that oscillating body that is external to that oscillating system. Suppose, in a playground, a boy is sitting on a swing. WebSep 12, 2024 · When an oscillator is forced with a periodic driving force, the motion may seem chaotic. The motions of the oscillator is known as transients. After the transients die out, the oscillator reaches a steady state, where the motion is periodic. After some time, the steady state solution to this differential equation is.

"WebFORCED OSCILLATIONS AND RESONANCE Suppose now that instead of allowing our system to oscillate in isolation we apply a "driving force". For example, in the case of the (vertical) mass on a spring the driving force might be applied by having an external force (F) move the support of the spring up and down.
