Physics 105, Fall Term, 2009
1) Simple harmonic
motion is a motion that repeats in a simple pattern.
2) When the location and time of an
object undergoing simple harmonic motion is graphed, it produces a sine
To visualize simple harmonic motion, go to:
Click through each of the links; watch the animations and read the text.
What do the motions of the spring, pendulum, and orbit have in common?
They all repeat their motion at the exact same rate.
What kind of curve is made by graphing the position of these objects in
these systems compared to time? (Hint: look at key concept #2)
A sine curve.
Does the amplitude, or maximum displacement from the center, of the motion for
these objects change?
Define simple harmonic motion.
Motion that repeats itself over a specific time interval with the same amplitude.
Which of the following is an example of simple harmonic motion (select all
A skateboarder in a half pipe
A fan blade while the fan is running
A guitar string after it is plucked
The motion of
A swimmer holding a constant pace for each
lap of the pool
The comments entered in these last two boxes go into a big anonymous data file that I will use to guide the lectures of the day. That means two things:
1) If you have a specific question or concern and would like an individual
answer you will need to come by the office or send an email.
2) If you really want to get an anonymous comment to me before the lecture, it
must be submitted before 11am that day.
Was there anything that you didn't understand in the reading assignment?
What was confusing to you?
