материальная точка - человек передвигается на расстояние, значительно болшее его размеров (например, несколько километров). Не является материальной точкой - если размеры человека сравнимы или больше преодолеваемого расстояния (Отойти от какого-то места на полшага).

Тело движется - движение человека. Тело не движется - человек стоит на месте.
