PHYSICS SPEED X VELOCITY

  1. The train moves 60 kilometers forward, and then 30 kilometers backwards. The whole journey takes 5 hours.
  2. What is the distance the train has travelled?
  3. What is the displacement of the train? What is the direction of the displacement?
  4. What is the average speed of the train?
  5. What is the average velocity of the train?


  1. The train moves 12 kilometers forward, and then 24 kilometers backwards. The whole journey takes 3 hours.
  2. What is the distance the train has travelled?
  3. What is the displacement of the train? What is the direction of the displacement?
  4. What is the average speed of the train?
  5. What is the average velocity of the train?


  1. The train moves 80,000 meters forward, and then 40,000 meters backwards, and then another 80,000 meters forward. The whole journey takes 120 minutes.
  2. What is the distance the train has travelled?
  3. What is the displacement of the train? What is the direction of the displacement?
  4. What is the average speed of the train?
  5. What is the average velocity of the train?


  1. The train moves 100,000 centimeters forward, and then 1,000,000 millimeters backwards. The whole journey started at 2pm, and ended at 2:30 pm the same day.
