Pretend you are being interviewed by a historian from a distant galaxy who is working on a report about Earth, but he or she is completely confused as to why Earthlings would invest in rollercoasters. You are an eighth-grade student who loves roller coasters and knows about potential and kinetic energy. You attempt to explain why they are fun. The interviewer seems to understand the science, but not the fun part. Using a complete sentence, attempt to explain to the historian why humans like roller coasters, and what they have to do with kinetic and potential energy?
