Give three examples of periodic motion
that are simple harmonic motion.

What measures are greatest at the equilibrium
position?

What measures are least at the equilibrium
position?

Janet wants to find the spring constant
of a given spring, so she hangs it vertically and attaches a 0.40 kg mass
to the end. What is the spring constant if the spring stretches 3.0
cm?

How many times does an object pass the
equilibrium position during a single cycle? (Use a diagram in your answer.)

What happens to the period when you make
the length of a pendulum four times as long? (Show your work!)

What would happen to the period if you
took your pendulum to a planet with four times as much gravity? (Show
your work!)

What is the period of a signal with a frequency
of 5 MHz? (Show your work!)

What is the frequency of something cycling
with a period of 0.25 seconds? (Show your work!)

Why do we ignore the mass of the string
of a pendulum and concentrate only on the bob?

Why does an acrobat swing past the equilibrium
position when there is no force acting on her at that point?

Draw a longitudinal wave. Label the
compression and stretching and identify one wavelength.

How fast is a wave moving at a frequency
of 5 Hz and a wavelength of 5 m?

How many nodes are there if a wave has
5 antinodes. (Show with a diagram.)
