Lesson: 2.8 Simple Harmonic Motion
Goal: To solve problems involving simple harmonic motion.
DOD
Sinusoidal: Graph of motion that is similar to a sine wave.
Frequency: Cycles per time period (usually seconds). It is the reciprocal of the
period.
and Ch_2 Page 1 and
represents time!
If Period , then Frequency (Frequency is the same as cycles per second)
Displacement: Amount a mass is pulled away from its resting position (a).

Examples
A weight is hanging at rest from a spring. At
, the weight is pulled down
units and released. It makes full cycles every second. Write an equation using
the following values of and , and the graph the equation. Ch_2 Page 2 Ch_2 Page 3 ...
