Periodic motion is motion that repeats itself.
Such motion generally results when a system is disturbed from its equilibrium position and the forces generated within the system as a result tend to restore the system back to its equilibrium position. The result is oscillatory motion of the system about its equilibrium position. The types of oscillatory motion you are perhaps most familiar with include such diverse phenomena as the motion of a child's swing and the motion of the moon around the earth. In this laboratory, you will use the experimental setup shown in Figure 1 to study simple harmonic motion of a hanging mass. In Activity 1, you will study the relationship among the displacement, velocity, acceleration of a mass experiencing simple harmonic motion Answer the following question concerning Activity 1.
