About

Intro Page You can change the liquid density or drag the object up/down to find out how the pressure(due to liquid) on the object are changed at different places around the object(Black Arrows).
The net force due to the pressure provide the buoyancy force.
The velocity vector is shown in red and acceleration is shown in blue.
In this model, we assume there is a drag force Fr=-b*vy when object is moving down, and the drag force is neglectable when moving up (may be this is not a good assumption). I would like to hear your suggestions.
I hope you can enjoy it! Enjoy the fun of Physics! You can access this simulation online from

For Teachers

 

Instructions

Combo Box and their Functions

 
Display will give you checkboxes
 
while Liquid Density, Object Density and b give sliders.



Draggable Block

You can drag the block vertically in the simulation as well.
The simulation will also be carried out in real-time,
and will auto-play upon release.

Toggling Full Screen

Double clicking anywhere in the panel will toggle full screen.
Only works if the simulation is paused.
 

Play/Pause, Step and Reset Buttons

 
Plays/Pauses, steps and resets the simulation respectively.
