Law Of Areas (Noun)
Meaning
A law concerning the speed at which planets travel; a line connecting a planet to the sun will sweep out equal areas in equal times; "Kepler's second law means that a planet's orbital speed changes with its distance from the sun".
Classification
Nouns denoting cognitive processes and contents.
Examples
- The law of areas states that the line connecting the planet to the sun sweeps out equal areas in equal times, indicating a faster speed when the planet is closer to the sun.
- According to Kepler's second law, the law of areas also implies that the planet's orbital speed changes with its distance from the sun.
- By studying the orbits of the planets, astronomers can use the law of areas to understand the pattern of their movements and predict their positions.
- The law of areas is particularly important for understanding the shape and size of planetary orbits and how they affect the planet's orbital speed.
- By applying the law of areas to a planet's orbit, astronomers can determine the amount of time it takes for the planet to complete one orbit around the sun.
