libration
Pronunciation: [laɪˈbreɪʃən]
Word
Context: "astronomy"
(noun) the slight movement of something that makes it look like it's wobbling. In space, it describes how we see the Moon moving a little as it orbits the Earth, so we can see different parts of it over time.
Example
The libration of the Moon allows us to see about 59% of its surface over time.
Example
If there was no libration, we would only see half of the Moon's surface from Earth.
Example
What causes the Moon's libration that lets us see more than just one side?
Context: "balance"
(noun) a gentle rocking or swaying movement, often used in a more abstract sense to describe balance or stability. Think of it like a seesaw that moves back and forth.
Example
The libration of the seesaw made it fun for the kids to play on.
Example
Without the libration, the seesaw remained still and no one had fun.
Example
How does the libration of the boat affect its stability in the water?
