  • This is the distance-time graph
  • From the start, the object moved away from the starting point [E] by constant speed
  • Then, it stopped for a while and walked towards the starting point [W] for few seconds
  • Then, it stopped for the rest of motion


  • This is velocity-time graph
  • The velocity was 0 for 2 seconds , this is the stopped motion
  • The velocity was 0.5 after 2 seconds until 5 seconds ; this is the walking motion [E]
  • The velocity was 0 at 5 seconds until 7 seconds; this is where there is no motion
  • The velocity was -0.5 until ends ; this is the walking motion [w]
  • velocity-time graph
  • At first, the velocity was increased 0 to 0.5 until 4 seconds; this is the speeding motion [E]
  • From 4 sec the velocity was constant until 6 seconds ; this is the constant speed movement [E]
  • From 6 the velocity was -0.4 until 9 seconds ; this is the slower speed movement[w]
  • Then, the motion stopped from 9 seconds.
  • distance-time graph
  • It started from 1 m , moved constant speed until 3seconds ; this is moving [E]
  • Then from 3 to 7 seconds,  this is the rest motion 
  • Then from 7 to 10 seconds ; this is the moving constant speed movement [E] 
  • velocity-time graph
  • At first the speed [E]was constant until 3 seconds and 4 seconds to 7 seconds, the speed was [W] constant then the motion stopped from 7 seconds
  • This is distance-time graph , it started from 3 meters , this is the constant speed [W]
  • Then it moved 3 seconds from rest motion until 4 seconds
  • Then it moved 4 seconds at constant speed [W] until 5 seconds
  • Then it moved 5 seconds at rest motion until 7 seconds
  • Then it moved 7 seconds to 10 seconds at constant speed [E] to 3meters.
