Question
Which of the following is NOT a vector
quantity? ÂSolution
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.
