That is, we consider the equation.Let us consider to the example of a mass on a spring. Damping occurs and the swing will oscillate with a smaller and smaller amplitude . m x ″ + c x ′ + k x = F ( t), ?. In Chapter 4 we explored the effect of damping on a system and we said that every system in the real world is, to a greater or lesser extent, a damped system in which energy is lost (dissipated) to the surroundings. Damping is a dissipating force that is always in the opposite direction to the direction of motion of the oscillating particle. However, when the two frequencies match or become the same, resonance occurs.Schlagwörter:Forced Oscillations and ResonancePhysicsExample of Forced Oscillation When the frequency difference between the system and that of the external force is minimal, the resultant amplitude of the forced oscillations will be enormous.The regular variation in position or magnitude about a central point or about a mean position is known as oscillation.Schlagwörter:Forced Oscillations and ResonanceExample of Forced Oscillation
