Forced harmonic oscillator. Notes by G.F. Bertsch, (2014). 1. The time-dependent wave function. The evolution of the ground state of the harmonic oscillator in the presence of a time- dependent driving force has an exact solution. It is useful to exhibit the solution as an aid in constructing approximations for more complicated
driving force to the system. We are surrounded by examples of such forced oscillations. Before discussing forced harmonic oscillator let us remember the properties and applications of damped harmonic oscillator described in the previous chapter. Review of Damped Harmonic Oscillator. The mechanical example of a mass
FORCED HARMONIC MOTION. Background. • Equation of Motion for Mass-Spring System: my (t) + µy (t) + ky(t) = F(t). y is displacement, m is mass, µ is damping constant, k is spring constant and F is external force. • RLC Circuit Equation: LI (t) + RI (t) +. 1. C. I(t) = E (t), where I is current, L is inductance, R is resistance,.
Lecture 7 - Forced harmonic motion. Text: Fowles and Cassiday, Chap. 3. Demo: driven spring. There are many situations in which a system may be driven by a regular or irregular external force. For example, machinery may vibrate its local enviroment; an electromagnet may vibrate the cone of a loudspeaker, an electrical
Forced (Driven) simple harmonic motion. Undamped forced oscillations: As we have seen in the last chapter that due to the resistance oscillations eventually die down. To maintain the oscillations one needs a driving force. First we shall study the forced oscillations without the damping term. So the basic equation of motion
10 Lecture 10: Forced (and damped) harmonic motion. In the previous lecture we introduced a new component into the harmonic oscillator, a dissipating force proportional to the velocity. The equation of motion we obtained was more involved, but it was still homogeneous. Now we consider in addition the application of an
