2) When our author describes a damped harmonic oscillator, the constant b tells you
the maximum amplitude of the oscillator.
how fast the amplitude of the oscillator decreases.
the ratio of the spring constant to the mass of the spring.
the ratio of the spring constant to the mass of the oscillating object.

4) A mass is oscillating up and down on the end of a spring. You would like to increase the number of times the mass goes up and down during one second of time. To do this, you could...

6) In lab, you hang a brass mass to the end of a spring. After you give it a push, it moves up and down several times but its amplitude decreases every time and comes to rest after about 23 second. we would say this system is a
simple harmonic oscillator.
critical harmonic oscillator.
damped harmonic oscillator.
force harmonic oscillator.

7) A mass is oscillating up and down on the end of a spring. The maximum distance the mass moves from the equilibrium position of the spring is its...

8) You put a mass on the end of a perfect spring so that it forms a simple harmonic oscillator that oscillates up and down with a period T. If you double the mass on the end of the spring, the period of the oscillator will...
