Friction Revision - Call List

(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

  1. Opposes motion
  2. Liquid and gases collectively called as a fluid.
  3. When one surface is in rest over another is known as static friction.
  4. When one surface slides over another then it opposes the motion of the body then it is known as friction.
  5. To decrease friction.
