Question

    Which of the following statements best describes the

    relationship between static friction and the normal force?
    A Static friction is independent of the normal force Correct Answer Incorrect Answer
    B Static friction is directly proportional to the normal force Correct Answer Incorrect Answer
    C Static friction is inversely proportional to the normal force Correct Answer Incorrect Answer
    D Static friction is proportional to the square of the normal force Correct Answer Incorrect Answer

    Solution

    Static friction, which prevents an object from moving when a force is applied, increases with the normal force exerted on the object's surface. The greater the normal force, the greater the static friction force opposing motion.
