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
