Use the interactive applet for visual understanding of speed time graphs.[br]This applet can model any given text problems of up to 5 distinct parts of a total journey. Updated 20 Sep 2017 to include option to better adjust the parts of journey.[br]Original version at [url=https://www.geogebra.org/m/YpTfUB6Z]https://www.geogebra.org/m/YpTfUB6Z[/url][br]You can use the ShowViewScaleControls to modify the scale and views of the axes, and values.[br]The horizontal is in time units (you can set it to seconds, minutes or hours), and the vertical is [br]in units per time unit so you can set it to metres or kilometres per time unit (depending on your x axis units)

Some questions based on initial diagram of applet for your self discovery[br]1. Find the distance travelled (units) for the first 20 units of time.[br]2. Is the car turning back between E & F?[br][br]Some questions/situations for you to explore.[br]3. Alter the speed time graph such that the car after time at 20 units (at C) slows down uniformly to stop and rests (does not move) [br] for the period from D to E for 10 time units. It then moves with uniform acceleration for another 10 time units such that the total[br] journey distance is 600 units.
