A mass-and-spring oscillator is damped due to friction. Which quantity does the damping cause to change the most as time passes? (Assume the oscillator is underdamped.)

• restoring force

• inertia

• amplitude

• frequency

• period

A simple pendulum that oscillates at 10° has a period of 3.2 seconds. What is the approximate length of the pendulum?

• 7.0 m

• 2.5 m

• 247.6 m

• 1.8 m

A pendulum with a 1.0 m string has a natural frequency of 0.50 Hz, while a pendulum with a 9.0 m string has a natural frequency of 0.17 Hz. Which statement best describes the relationship between pendulum length and pendulum period?

• Period is independent of length.

• An increase in length corresponds to an increase in period.

• The relationship depends on the specific lengths we are investigating.

• An increase in length corresponds to a decrease in period.

• The relationship depends on the specific frequencies we are investigating.

A pendulum is oscillating with a natural frequency f = 3 Hz. If the length of the pendulum increases by a factor of 4 what happens to the frequency?

• increases by a factor of 2

• does not change

• increases by a factor of 4

• decreases by a factor of 2

• decreases by a factor of 4
