Observe, investigate and experiment with fully functioning replicas of machines, structures and amusement park rides, when K'NEX: Building Thrill Rides at the American Museum of Science and Energy in Oak Ridge.

Where does a Roller coaster car have the most Potential Energy and how is it converted to Kinetic Energy? This is just one of many questions that is answered in K'NEX: Building Thrill Rides, a special exhibition that captivates young visitors and provides them the opportunity to explore the science, math and technology behind hair-raising amusement park thrill rides.

There are 15 working thrill ride models, constructed solely from K'NEX rods and connectors, that combine the principles of geometry, physics, and mechanics. The realistic actions of the models bring scientific and engineering concepts to life for students, who can conduct simple experiments to explore physical forces such as potential and kinetic energy, and linear and rotational motion.
