4 cards from this section. Quick, good the night before a test.
What is damping?
Think of a swinging object losing height over time.
List the types of damping.
Focus on the adjectives that describe how the system behaves.
What happens to the amplitude of a damped harmonic oscillator over time?
Consider the effects of air resistance and friction.
True or False: An overdamped system will oscillate.
Think about the motion's characteristics.
If a damped harmonic oscillator has a natural frequency of 10 rad/s and a damping coefficient that leads to Q=2, calculate the damping coefficient.
Remember to rearrange the Q Formula.
A mass on a spring undergoes underdamped oscillation with an amplitude that decreases from 10 cm to 5 cm in 5 seconds. Calculate the decay constant γ.
Use logarithms to isolate γ.
