What does isochronism in relation to pendulums refer to?

Isochronism in relation to pendulums refers to the property of being able to swing with a constant period, regardless of the amplitude of the swing, as long as the angle is small. This characteristic means that a pendulum will take the same amount of time to complete each swing, thus ensuring the equality of time intervals for each oscillation. This principle is fundamental to the functioning of clocks that employ pendulums, as it allows for reliable timekeeping.

Understanding isochronism is crucial for grasping how pendulum clocks operate, as it demonstrates that the time it takes for a pendulum to return to its starting point remains consistent, allowing for precise measurement of time.
