Wikipedia

friction (uncountable)

  1. The rubbing of one object or surface against another.
    • 2013 July-August, Henry Petroski, “Geothermal Energy”, American Scientist, volume 101, number 4: 
      Energy has seldom been found where we need it when we want it. Ancient nomads, wishing to ward off the evening chill and enjoy a meal around a campfire, had to collect wood and then spend time and effort coaxing the heat of friction out from between sticks to kindle a flame.
  2. Conflict, as between persons having dissimilar ideas or interests; clash.
  3. (physics): A force that resists the relative motion or tendency to such motion of two bodies in contact.
    • 1839, Denison Olmsted, A Compendium of Astronomy Page 95
      Secondly, When a body is once in motion it will continue to move forever, unless something stops it. When a ball is struck on the surface of the earth, the friction of the earth and the resistance of the air soon stop its motion.
