kinematics

• average speed = total distance travelled/total time taken
• uniform speed: the distance travelled for every unit of time is the same
• distance

  • total length travelled by a moving object regardless of direction of motion
  • has magnitude only
  • SI unit is metre (m)

  displacement

  • distance measured in a straight line from the starting point
  • has magnitude and direction
  • SI unit is metre (m)
