This applet try to simulate buoyancy force for object with different density relative to the fluid.

You can adjust density for two objects (square and circle shape with the same density) or liquid.
If the density of the liquid and object are the same. It becomes one system.
Hope this can help you understand the source of buoyancy force.
surrounding liquid need to support the same volumn of liquid which is replaced by object.
So the buoyancy force equal the weight of the liquid occupied by the object.

What will happened if we add another liquid with density less than original liquid?
Will those objects moving up? or moving down? WHY?
You can click the top right check box to add another liquid to the system.
You can remove those liquid if you click another check box

Enjoy it! :-)

  • 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!


The following is a flash video (as an example to show you how to play with it).
