WebbDefinition of Forced Simple Harmonic Motion. When we displace a system, say a simple pendulum, from its equilibrium position and then release it, it oscillates with a natural frequency ω and these oscillations are free oscillations. But all free oscillations eventually die out due to the everpresent damping forces in the surrounding. WebbSimple Harmonic Motion. A mass on a vertical spring. The simple pendulum.

WebbThe mathematical formula that describes damped harmonic motion is A e-γt cos (ω t + φ) where γ = b/2m. Notice that this is the same cosine function for simple harmonic motion but the amplitude, A, is multiplied by an exponentially decreasing function of time, e-γt. WebbDamping continues until the oscillator comes to rest at the equilibrium position; A key feature of simple harmonic motion is that the frequency of damped oscillations does not change as the amplitude decreases; For example, a child on a swing can oscillate back and forth once every second, but this time remains the same regardless of the amplitude howard county gis data
