Among all the things that move, what makes some have periodic motion?
motion repeated regularly
motion in 1 direction (vector)
motion accelerates
motion cancels another motion

If the x axis is time, what is the interval from peak to peak called?
the crests
the rotation
the period or wavelength
the original oscillation
What is the distance of the light grey lines called?
