  • Covers equal distances in equal time interval.
  • Covers unequal distances in equal time interval.
  • Average speed is similar to actual speed of the object.
  • Average speed is different from actual speed of the object.
  • Distance-time graph shows a straight line.
  • Distance-time graph shows a curved line.

  • Rectilinear motion has non-zero acceleration.
