One of the most visceral sensations a human can experience is a sudden fall. This quick, downward acceleration of the human body can evoke feelings of terror if it’s unplanned or unwanted, or feelings of thrill and delight when it’s expected. For many of us, the sudden pull of gravity conjures up all these feelings at once. Roller coasters tap into this concept, and they meticulously curate it in order to maximize these feelings for their riders. A ride on a roller coaster pushes and pulls your body in myriad different directions, allowing a rider to experience gravity-like forces in many different directions. It’s an experience rooted in verticality, which is what gives them such appeal.
