Question

If we spill oil on the floor, the friction of the floor will

  1. Increase
  2. Decrease
  3. Cannot say
  4. Will remain unchanged

hintHint:

The oil has much lesser value of coefficient of friction than that of a regular floor.

The correct answer is: Decrease


    • The expression for the frictional force is given as,
      Fequals mu N
      Where, μ is the coefficient of friction and N is the normal force acting between the body and the surface.
    • The oil has much lesser value of coefficient of friction than that of a regular floor. When we put oil on a floor the coefficient of friction decreases which will cause the friction to decrease as well.

    How does friction affect speed?

    Friction is the force opposing one solid object's movement over another. Four categories of friction exist fluid friction, rolling friction, sliding friction, and static friction.
    ¶The frictional force keeps our feet planted on the ground when we walk on or on the floor. As a result, we frequently slip on icy or slippery surfaces because there is less friction.
    ¶According to scientists, friction is caused by the interactions of tiny bumps on surfaces as they rub against each other. The bumps on each surface bend and exert force on each other, making it difficult for the surfaces to slip over each other.
