Questions
c
Discuss your graphs of pendulum period versus mass and length. What relationship between mass and length
produces a straight line graph?
d
Did the period of your pendulum vary with the mass of the bob? Discuss why it did or did not.
e
Was mechanical energy conserved during a single swing of the pendulum?
f
No matter how high the initial height of the bob, the pendulum ultimately slows down and stops. Does this
slowing down defy the principle of the conservation of energy? Explain.
