What does velocity include that speed does not?

• A. Magnitude only
• B. Direction
• C. Acceleration
• D. Time

Answer: (B)

Velocity is a vector quantity, which means it includes both magnitude (how fast something is moving) and direction (the path along which the object is moving). Speed, on the other hand, is a scalar quantity, which only considers the magnitude, representing how fast an object is traveling without any regard to the direction of that travel. Thus, velocity provides a more comprehensive understanding of motion by indicating both how fast an object is moving and in which direction. This distinction clearly highlights that the correct answer involves direction, which is not accounted for when discussing speed alone.
