Let's explore a graph which illustrates the linear motion without acceleration of the car shown below the graph.[br]Click the [color=#0a971e][i]Start / Stop[/i][/color] button to start or pause the motion of the car.[br]Look at the car moving and compare its motion with the position-time graph.[br]You can also modify the graph by dragging the points shown as big [color=#1551b5][i]X[/i][/color].[br]To drive the car back to the start point, click the [color=#c51414][i]Restart[/i][/color] button.[br][br]Select the [color=#0a971e][i]Velocity [/i][/color] box to view the velocity graph in the different parts of the motion.[br]Since that graph is plotted in the same coordinate system of the previous one, consider the value of speed measured in [color=#1551b5][i]m/s[/i][/color] (meters/second).[br]To delete the velocity graph, click the[color=#888] [i]Delete traces[/i][/color] button.
