 Each student is responsible for creating a line plot of amplitude of each
swing versus mean time it takes to make that swing on his or her own graph
paper.
 Once you plot the data you have the "picture" of the period.
 Your guess of that period is
 How would the results be different if instead of a string 30 cm
long, we used 10 cm string?
How about a string 100 cm long?
 Summarize the relationship that you may see with time or
swings and the use of different length string.
 This relationship is actually defined by certain laws of
physics. These laws let us say that the period is equal to
Where g is the acceleration due to gravity (here on Earth it has
a value of 9.8 m/sec^{2}.), L is the length of the pendulum string
from where it is tied at the top to where the center of mass is
of the tied object, and pi = 3.14.
Does your guessed period in question 3 confirm this? Prove
this by showing your work below.
