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?

• 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.
