    The student explains that this path is the result of -

    answer choices

    the magnetic attraction between Earth and the sun

    Q.

    An object will continue moving in a straight line unless it is acted on by an unbalanced force. Which of the following best explains Earth's motion?

    answer choices

    There is no unbalanced force acting on Earth because space is empty and nothing touches Earth.

    The gravitational force pulling Earth toward the sun is equal and opposite to the force pulling the sun toward Earth, so there is no unbalanced force acting on Earth.

    The sun moves in an elliptical orbit around Earth, and the sun's gravity pulls Earth along.

    Earth moves in an elliptical orbit around the sun because the gravitational force of the sun attracts Earth.
