### Test 1

Question | Answer |
---|---|

Resonance is | when driving frequency is equal to the natural frequency of the oscillator. |

Oscillations:(y)t= | A cos(wt+Oo) |

Amplitude | m |

omega(w)= | rad/s |

Phase= | rad |

Phase Shift= | rad |

omega(w)= | squrt(k/m) or 2(pi)f |

frequency(f)= | 1/T |

T= | 2(pi)sqrt(m/k) |

K= | N/m |

Vmax= | omega(w)*A |

amax= | omega(w)^2*A |

Kmax= | (1/2)*k*A^2 |

Pendulum: omega(w)= | squrt(g/l) |

pendulum: T= | 2(pi)squrt(L/g) |

k= | m*omega^2 |

damped oscillations: y(t)= | Ae^(-t/T) |

Pendulum: F= | 1/(2pi)*squrt(g/L) |

Pendulum: T= | 2(pi)*squrt(L/g) |

Waves: Vs= | squrt(Ts/(mass/L)) |

Sound: B= | 10log(I/Io) |

Standing Wave: f= | m(V/2*L) |

sound: wavelength()= | 2L/m |
