identify as speed velocity\n20 m/s \nscalar \n15 m/s south \n32 m/s \nvector \n10 m/s in a circle

Answer

Brief Explanations:

Speed is a scalar quantity that only has magnitude. Velocity is a vector quantity that has both magnitude and direction. A scalar has only magnitude, while a vector has magnitude and direction.

  1. "20 m/s" has only magnitude, so it is speed and a scalar.
  2. "scalar" is a general term for quantities like speed, not speed or velocity itself in a specific - value sense.
  3. "15 m/s South" has magnitude and direction, so it is velocity.
  4. "32 m/s" has only magnitude, so it is speed.
  5. "vector" is a general term for quantities like velocity, not speed or velocity itself in a specific - value sense.
  6. "10 m/s in a circle" has magnitude and direction (the direction is constantly changing in circular motion), so it is velocity.
