Question

Why the Moon's orbital velocity is slowest when the Moon is farthest from Earth.

Answer 1

Answer:

The speed of the Moon is slower when it is farther from Earth because the Moon is hindered by the tides of the Earth, causing its orbital period to grow

Explanation:

The Moon grows tides on Earth. As the Earth rotates, the waters produce friction within the liquid and between the solid earth. This friction causes the Earth to rotate slowly, and because of this the days become long. However, this slow movement of the Earth causes the Moon to move away from the angular momentum of the Earth-Moon system must be preserved, so the slow rotation of the Earth requires the Moon to move away progressively, because the angular momentum Earth-Moon must be preserved. This also causes the Moon's orbital period to increase, because the tides hinder the Moon, making it turn slowly.

Answer 2

 it is farthest from the sun. As the earth moves around the sun it moves in an eliptical orbit as it gets closer it speeds up and as it moves away it slows down.
