This following applet is Buoyancy force with drag force
Created by prof Hwang Modified by Ahmed
Orginal project Buoyancy force with drag force

Embed a running copy of this simulation

Embed a running copy link(show simulation in a popuped window)
Full screen applet or Problem viewing java?Add http://www.phy.ntnu.edu.tw/ to exception site list
• Please feel free to post your ideas about how to use the simulation for better teaching and learning.
• Post questions to be asked to help students to think, to explore.
• Upload worksheets as attached files to share with more users.
Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!

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).
