Roller coasters operate without engines, using forces like electromagnetism, gravity, and acceleration to create thrilling experiences. Electromagnets propel the cars, while gravity induces free fall, causing sensations of weightlessness. Acceleration and deceleration affect how riders feel in their seats. The loop, a key thrill element, uses centripetal force to keep riders secure while inducing dizziness. These forces combine to deliver an exhilarating ride.
