Masses Go To and Fro

• Oscillating Systems

2
Periodic Motion

• OSCILLATION a periodic variation from one state
  to another
• SIMPLE HARMONIC OSCILLATOR an object that
  repeats a periodic motion

3
Simple Harmonic Motion

• PERIOD the time in which a complete oscillation
  occurs (seconds)
• FREQUENCY the number of oscillations that a
  system completes in one second (Hertz)

4
Pendulum

• What are the controllable factors in creating a
  pendulum?
• LENGTH
• MASS
• RELEASE ANGLE
• Period of a pendulum is the time for one complete
  swing.
• How do the controllable factors change the
  period?
• Determine in Lab

Mass on a Spring

• What are the controllable factors in creating a
  mass/spring system?
• SPRING CONSTANT
• MASS
• RELEASE POSITION
• Period of a mass on a spring is the time for one
  complete oscillation.
• How do the controllable factors change the
  period?
• Inversely proportional to SPRING CONSTANT
• Proportional to MASS
