A student makes a model of the sun-Earth system by swinging a ball around her head. Using this 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
