A Build your own Simulator Kit for Students - Everything Included!  (links are at page bottom)

 

Statement of the Problem: A soccer player is running down the field in straight line parallel to the sideline. Where is he when the angle α of success for making a goal is at a maximum? 

THERE ARE 2 DIFFERENT SIMULATORS HERE - GeoGebra simulator    Scratch simulator

InterActivity 1: Soccer Player Goal Simulator 1 - GeoGebra   Watch Mathcast

Click on the play button at bottom left of simulator or click & drag the slider point bottom to animate manually.
Find bottom when the angle α of success is a maximum. More directions below.

Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and active in your browser (Click here to install Java now)

More Directions

  • As you click and drag the slider point bottom towards the left, notice that the angle α of success increases and then it starts to decrease. Move the slider slowly and find the value of bottom that makes the angle α of success a maximum. 
    (With a goal size g=1 and a parallel side1=2.1 from the lower goal post, the maximum angle α  is when bottom=2.55.)
  • To reset: click on in upper right corner.
  • To move a slider to step-by-step, click on the slider point once without moving. It will glow. Use left/right arrow keys.
Double-click to open the GeoGebra file on your computer with all menus and tools.
  • To save, select command: File -> SaveAs.
  • To move a slider to an exact value either:
    • In the Input Bar (bottom left) type: variable=value (e.g. bottom=2.55) and hit Enter or
