Linear motion without acceleration

Let's explore a linear motion without acceleration. Select the type of graph you want to show by clicking the related checkbox. Type the speed of the car in the speed box, then press the Enter key to confirm. Start and stop the animation by clicking the Start/Stop button. To drive the car back to its start position click the Restart button. Compare the graphs you obtain setting different speeds, each time driving the car back to the start point without deleting the traces and modifying the speed value. What do you observe? How do Position vs Time and Velocity vs Time graph change? To delete the graph click the Delete traces button.
