A pendulum with a period of 1.8 s on Earth is moved to another planet. On the new planet, its period is 2.5 s. What can you conclude about this new planet?

The force of gravity on the new planet is less than it is on Earth. The period of a pendulum is inversely related to acceleration due to gravity. Therefore, if the period of the given pendulum increases, it must be due to a decrease in the force of gravity.
