This tutorial will demonstrate various settings of the Soft Body Tag using the same object for comparison.
The object file is included here to play along if you want.
You just need to add the Soft Body Tag to the object and change the settings accordingly.
With each example I'll include an image of the SB Tag Panel,
frame rate setting and the Dynamics settings.
Remember the Dynamics work only when the animation is running.
Different frame rate settings change the behavior drastically and
these examples start at 12 fps. So if you're final goal is animation you
may want 24 or 30 fps, so the examples at 12 fps will not behave as expected.
If you need still images, any frame rate may be used if it gets you what you want.
The Soft Body Tag is a deep moat to get lost in and this will just scratch the surface.
