Hypothesis
My hypothesis is that as the length of the pendulum increases the time it takes to swing will
increase. As the length increases it will loose time due to the oscillation happening. I believe
the reason is because it takes longer to complete the cycle. An example are the swings, if
the length of the string would’ve been shorter, the time for it to stop working would’ve been a
lot faster than a longer string. The independent variable in this experiment is the length of
the strings and the variable we’re going to measure if the time it takes for 1 swing.

Variables:
length of the pendulum,
Independent: length of the string
Dependent; time it takes for 1 swing
Controlled: string, timer, ruler and a cookie cutter (mass of the bob at the end of the
pendulum)
hypothesis
1) how the length of a pendulum affects the time it takes to swing
2) The length of a pendulum affects the time it takes to swing by its size. I think that if
the length of the pendulum increases the time it takes will increase and if the length
of the pendulum decreases the time it takes will decrease.
