Tap and select the shape and material of your bob.
Tap on the bob to modify its volume.
Drag the spring balance to immerse the bob in fluid.
Archimedes Principle: The buoyant force equals the weight of displaced liquid.
Also: The volume of displaced liquid equals the immersed volume of the bob.
Also: The volume of displaced liquid equals the immersed volume of the bob.
Increase the volume of the bob and immerse again.
Archimedes Principle can be verified with the bob at any volume.
Tap on an alternative shape and immerse bob again.
Archimedes Principle can be verified again.
Draw the spring balance out, and tap “RESET” to start fresh
Choose a spherical wooden bob to immerse.
We will now compare floating to complete immersion.
Make the bob immerse completely by modifying the density of the fluid. Archimedes Principle works in all cases.
