How does the amount of mass effect the number of cycles of a pendulum?

The mass of a pendulum does not significantly affect the number of cycles it completes in a given time period. The period of a simple pendulum, which is the time taken for one complete cycle, depends primarily on its length and the acceleration due to gravity, but not on its mass. Therefore, while a heavier pendulum will have more mass, it will still oscillate with the same frequency as a lighter pendulum of the same length under ideal conditions.
