Quantity that includes direction and rate of displacement is what?

• A. Mass
• B. Velocity
• C. Acceleration
• D. Scalar

Answer: (B)

Velocity is the quantity that describes how fast something is moving and in what direction. It’s a vector, so it has both magnitude (the rate of displacement) and direction. Mass is a scalar with only magnitude, and acceleration is the rate of change of velocity (how velocity changes over time), not the current rate of displacement. Scalars have magnitude only and no direction.
