Correct answer: "Velocity is speed and direction together."
Explanation: Speed is a scalar (only magnitude, e.g., 10 m/s). Velocity is a vector — it includes both magnitude and direction (e.g., 10 m/s north). Two objects can have the same speed but different velocities if they move in different directions. Velocity changes when either the speed or the direction changes (so you can have constant speed but changing velocity, as in uniform circular motion).
