10. Based on Kepler's observations about planetary motion, what is the relationship between a planet's orbital velocity and its distance from the sun?

The greater the distance, the slower the orbital velocity.
Distance has no effect on orbital velocity.
The greater the distance, the greater the orbital velocity.
As distance is cut in half, orbital velocity decreases.
The greater the distance, the slower the orbital velocity.
1 point: "The greater the distance, the slower the orbital velocity."
According to Kepler's observations, the relationship between a planet's orbital velocity and its distance from the sun is as follows: The greater the distance, the slower the orbital velocity. In other words, as a planet moves farther away from the sun, its orbital velocity decreases.
Kepler's Third Law of Planetary Motion, also known as the Law of Harmonies, states that the square of a planet's orbital period is proportional to the cube of its average distance from the sun. This means that as the distance from the sun increases, the orbital period (the time it takes for a planet to complete one orbit around the sun) also increases. Since velocity is defined as the distance traveled per unit time, a longer orbital period results in a slower orbital velocity.
So, in summary, the greater the distance a planet is from the sun, the slower its orbital velocity will be.
