    Gregory rolls a plastic ball on the floor. The ball stops after rolling a certain distance. The ball stops because of the presence of

    A)  Gravitational force  

    B)  Frictional force

    C)  Magnetic force               

    D)  Electric force

    Correct Answer: B

    Solution :

      Friction can be defined as the resistance hindering the relative movement, or the propensity toward such a movement, of two surfaces that are in contact. It is because of this resistance that the ball stops after rolling a certain distance. Hence, the ball stops because of the presence of frictional force. The correct answer is B.
