Question

    Which of the following quantities is a

    scalar?  
    A Force Correct Answer Incorrect Answer
    B Velocity Correct Answer Incorrect Answer
    C Displacement Correct Answer Incorrect Answer
    D Work Correct Answer Incorrect Answer

    Solution

    Work is a scalar quantity, as it only has magnitude and no specific direction.   In contrast, force, velocity, and displacement are vector quantities because they have both magnitude and direction.   Work is calculated as the product of force and displacement in the direction of the force.
