Oscillation for which the amplitude decreases with time as work is done against resistive forces 2 of 6 When does the velocity of a simple harmonic oscillator reach a maximum? When the displacement is zero 3 of 6 The is the velocity of a simple harmonic oscillator equal to zero? When the displacements at a maximum 4 of 6 What is a forced vibration? An oscillation caused by an external varying force 5 of 6 What is a free oscillation? One in which a body or system oscillates at its natural frequency 6 of 6
