Answer:

Newton's laws of motion and gravity explained Earth's annual journey around the Sun. Earth would move straight forward through the universe, but the Sun exerts a constant pull on our planet. This force bends Earth's path toward the Sun, pulling the planet into an elliptical (almost circular) orbit.
