General Applet Instructions
Any applet in the Friction Lab has three areas as shown
in the screen shot below.
Click on an area to learn about its function.
Animation Control Center
The animation of the experiment is controlled by a few buttons.
Usually the following four buttons are always present:
- single step
- Proceeds a single step further if animation is not running.
- start
- Starts animation if not already started.
- stop
- Stops animation if not already stopped.
- reset
- Resets the experiment to a predefined initial state.
Parameter Control Center
An experiment is usually controlled by several parameters.
You can change these parameters by the control elements.
There are two types of control elements:
The parameters of the experiment can be changed even when it is
already running.
Note: Numerical entries have to be confirmed by pressing the ENTER
key in order to become effective.
Animated Experiment
In this area the experiment is visualized. When the start button
in the Animation Control Center is pressed you
will see the animated dynamics of the system.
By manipulating the control elements in the
Parameter Control Center
you can watch how the behaviour of the system will change.
In some experiments you can manipulate objects
in this area with the mouse.
