Which of the following changes would
increase the overall period of a pendulum?
You may assume that any changes are by
the same factor.
(A) To increase the period of a pendulum, we
can increase the length of the pendulum
and take it to a planet, like Mars, that has a
smaller acceleration due to gravity than
Earth.
(B) To increase the period of a
pendulum, we can add more mass to
the bottom of the pendulum and take
it to a planet, like Jupiter, that has a
larger acceleration due to gravity
than Earth.
(C) To increase the period of a
pendulum, we can take the
pendulum to a planet, like
Jupiter, that has a larger
acceleration due to gravity than
Earth and increase the mass at
the bottom of the pendulum.
(D) To increase the period of the
pendulum, we can take the pendulum
to a planet, like Mars, with a smaller
acceleration due to gravity than Earth
and shorten the length of the
pendulum.
