Pretend you and your lab partner are designers for the PhET simulations and want to make a simulation for students to investigate gravity fields. Think about what you know about gravity and what kinds of experiments a student might want to do to learn about gravity. You may have to refresh your memory by using the text. Draw a design, by hand, for a gravity simulation. Explain why you included each component and explain at least one experiment that a student could do.
