    Ted learns about force of friction. He tries out different ways of reducing as well as increasing the friction on the surface of his driveway. In order to increase the friction on the surface of the driveway, Ted should

    A)  Cover it with small pebbles

    B)  Cover it with wax

    C)  Pour water on it

    D)  Pour oil on it

    Correct Answer: A

    Solution :

      In order to increase the friction on the surface of his driveway, Ted should increase the roughness of its surface. He should do so because greater frictional force is generated on rough surfaces. Hence, in order to increase the friction on the surface of the driveway, he should cover it with small pebbles. The correct answer is A.
