A student makes a model of the sun–Earth system by swinging a ball around her head. Using the model, the student is trying to explain how earth stays on a path around the sun. The student explains that this path is the result of —

• The magnetic attraction between Earth and the sun

• potential energy stored in Earth that originated in the sun

• the gravitational attraction between the sun and Earth

• electromagnetic energy from the sun pulling on Earth
