UPCAT Science practice question 31: Which statement correctly distinguishes velocity from speed?

Correct answer

C. Velocity specifies direction, while speed does not.

Speed is a scalar, giving magnitude only. Velocity is a vector, giving both magnitude and direction. Both use m/s.

Which statement correctly distinguishes velocity from speed?

  1. Velocity is always larger than speed.
  2. Speed applies only to objects in free fall.
  3. Velocity specifies direction, while speed does not.Correct
  4. Speed is measured in m/s and velocity in m/s².

Why C is correct

Speed is a scalar, giving magnitude only. Velocity is a vector, giving both magnitude and direction. Both use m/s.
