Американские горки представляют собой железнодорожную систему специальной конструкции, спроектированной так, чтобы состав вагонеток с пассажирами, проходящий по ней, резко изменял направление и скорость движения.
ПЕРЕВОД: They represent a railway system of a special design, designed so that the composition of trolleys with passengers passing along it, sharply changed the direction and speed of movement. Since the trolleys do not have their own energy source, the acceleration uses the transformation of the potential energy of the composition into kinetic and vice versa.
