Distance & Displacement

Distance - overall how far (road)

Displacement - how far in a particular direction (direction)

1 of 3

Speed & Velocity

  • speed = distance / time
  • velocity = displacement / time
  • velocity = direction
2 of 3

Acceleration

  • rate of change in velocity
  • acceleration or decceleration = change in velocity / time
  • acceleration = speeding up (positive no.)
  • decceleration = slowing down (negative no.)
  • acceleration is used to describe decceleration with ' - '
  • acceleration - = decceleration
