Why does the speed of a planet decrease as it moves away from the sun?
(1 point)
The direction of the sun’s pull relative to the planet’s motion changes.
The planet’s inertia begins to point inward toward the sun.
The sun’s gravitational pull on the sun decreases.
The planet’s inertia begins to point backward along its orbit.

To answer your question, we need to categorize the provided statements correctly.

  1. Items to Drag:
    • Includes eight planets.
    • Earth is at the center of the solar system.
    • The Sun is at the center of the solar system.
    • Includes five planets.
    • The orbits of the planets are elliptical.
    • The orbits of the planets are circular.

Correct Categorization:

  • True Statements about the Solar System:

    • Includes eight planets.
    • The Sun is at the center of the solar system.
    • The orbits of the planets are elliptical.

  • False Statements about the Solar System:

    • Earth is at the center of the solar system.
    • Includes five planets.
    • The orbits of the planets are circular.
  1. Why does the speed of a planet decrease as it moves away from the sun?
  • The correct reason is: The direction of the sun’s pull relative to the planet’s motion changes.

This is because, as a planet moves in its elliptical orbit, the gravitational force from the sun creates a changing direction of acceleration that affects the planet's speed, decreasing it as the planet moves further away from the sun.

So, in summary:

  • For the solar system statements:

    • True: The Sun is at the center of the solar system, Includes eight planets, The orbits of the planets are elliptical.
    • False: Earth is at the center of the solar system, Includes five planets, The orbits of the planets are circular.

  • For the reason the speed decreases: The direction of the sun’s pull relative to the planet’s motion changes.
