    Question

    Which of the following is NOT a vector

    quantity?  
    A Displacement Correct Answer Incorrect Answer
    B Force Correct Answer Incorrect Answer
    C Speed Correct Answer Incorrect Answer
    D Acceleration Correct Answer Incorrect Answer

    Solution

    Speed only has magnitude and no direction, making it a scalar.   Vector quantities require both magnitude and direction (like velocity, displacement).   Understanding this helps differentiate motion types.   It is key in kinematics and projectile motion.
