Объяснение:
Трение является однойиз важнейших сил природы, связанное с превращением механической энергии вколебательную, внутреннюю и тепловую.
Движение требуетпреодоления силы трения и человек веками искал ее уменьшения. Онпридумал колесо, сани и водный транспорт, смазку и подшипники, заменяя ее насилу трения качения и скольжения, значения которых гораздо меньше.
Человек давно пользуется этим,используя водные пути и санки зимой вместо колёс, смазку и обтекаемую форму.Водные пути веками определяли распространение и связи людей, воздушные далипреимущество в большой скорости за счет уменьшения трения и для того жесамолеты поднимаются выше 10км и ракеты в безвоздушном пространстве.
