speed vs velocity

Cards (8)

  • distance travelled is only magnitude of displacement, not direction of displacement.
  • velocity = displacement/time
  • displacement is the change in position from one point to another
  • displacement can be positive or negative depending on the direction it's moving
  • velocity always has a sign to show its direction
  • speed is a scalar quantity, it has only magnitude , it is measured in metres per second.
  • velocity is a vector quantity, meaning it has both a magnitude and a direction
  • speed = distance / time (m/s)
