Linear motion - Overtaking process
A truck starts on the highway in St. Pölten and drives with 80 km/h in the direction of Salzburg. At the same time, a car in Vienna, which is 60 km from St. Pölten, starts driving with 130 km/h in the direction of Salzburg.

(a) Play the animation in the upper window and describe your observations.
(b) Click on "show" in the graphics window below and play the animation. Discuss the representation in the path-time diagram. The following questions may be helpful:
• What happens at the intersection point of the two straight lines?
• How can you read the distance traveled by both vehicles off the diagram?
• How can you read the speed of both vehicles off the diagram?
(c) Change the speed of the car and the truck. How does the representation in the path-time diagram change? What happens when both vehicles drive with same speed?
(d) Change the speed of the truck to 90 km/h and that of the car to 120 km/h. How does this affect the representation in the path-time diagram? When and where does the car pass the truck now?
