Meet mechanical engineer and roller coaster designer Chris Gray, in this video adapted from DESIGN SQUAD. Mechanical engineers use their knowledge of science to design and build all kinds of machines, including roller coasters. Chris explains how gravity and the changes in energy—between its potential and kinetic forms—create the excitement of a roller coaster ride.
This video is available in both English and Spanish audio, along with corresponding closed captions.
