(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.

Nature of the surfaces
Kinetic friction
Opposes motion
Friction offered by fluid due to liquid and gases.
Friction
When one surface slides or moves over another sliding or kinetic friction.
Limiting friction
When one surface is in rest over another is known as static friction.
Rolling friction
Fluid friction
Independent of area of contact surfaces
Static friction
Wear and tear of machinery parts
Weight of the body
Due to irregularities
Due to adhesive force
Produces heat
Liquid and gases collectively called as a fluid.
When one surface slides over another then it opposes the motion of the body then it is known as friction.
Contact force
Newton( N)
To decrease friction.
Sliding friction
When one surface rolls over another surface is known as rolling friction.
