What does pendula means?

"Pendula" is the plural form of "pendulum," which is a weight suspended from a pivot so that it can swing freely.

Here are some examples of how "pendula" might be used:

* "The clockmaker carefully adjusted the pendula of all the grandfather clocks."

* "The scientist used a set of pendula to demonstrate the laws of gravity."

* "The swinging pendula of the Foucault's pendulum experiment proved the rotation of the Earth."

So, "pendula" refers to multiple pendulums.
