Intro Page A block with width to height ratio equals to 0.4 sinks to a liquid.
You can change the width/height ratio with slider to study the atability of that object.
Drag force is proportional to the velocity: F=-bv in this  model.
I hope you can enjoy it as much as I do!

Enjoy the fun of Physics! You can access this simulation online from

Combo Box and Options

Display gives you checkboxes
While the rest give you sliders


Adjustable Block

You can adjust the block by dragging the empty squares respectively.
The centre square adjusts the vertical position of the block.
(Default Position)

(Dragging the block down)

(Dragging the block up)
Note that this can also be done in the Combo Box option: Position.
Releasing the block will also cause the simulation to auto-play.
The other two boxes adjusts the size of the block.
(Default Size)
(Possible Size 1)
(Possible Size 2)
This can also be done under the Combo Box Option: Width:Height.

Toggling Full Screen

Double clicking on the panel allows you toggle full screen.
Note that this only works when the simulation is paused.

Play/Pause and Reset Buttons

Plays/Pauses and resets the simulation.
