All you do is take very small increments on each movement. REMEMBER! This is not a tutorial for realism. That you have to do on your own. A picture is posted for an example of what I mean for the increments. (sorry about the lines on the pic. My paint program did that for reasons unknown)
THIS IS A SCREENSHOT OF WHAT I MEAN

This is about the end result of that (note not the same but its about the same result) If you are going to use this way make sure before you start to make your frame speed all the way down and then speed it up when you are done. Then it will look uber smooth without being slow. remember this is only my style of walking. There are many different styles. Try to find your own.
THIS IS AN EXAMPLE

HERE IS A SLOWER VERSION

SPACING
Next is spacing. The example I'm gonna use is making a ball drop. It should space differently because of gravity every single time (Note this will help with realism if you use it for sticks and such too.) Here is a picture.

This is without spacing
this is with spacing

MAKING IT BOUNCE WITH PHYSICS
Making the ball bounce also has to do with spacing. It's very hard to show it in screenshots so I'm going to type for it and show an example. You basicly do the same thing. Start going small Increments go into bigger increments. Now how long it gets depends on how many frames you have. Remember this. The only "hard" part of this is when the ball bounces back up to the designated height to make a frame or two where it is barely moving. (about as much as the small increments tut) then use spacing once again to bring it back down. Here is an example.

So today you have learned two ways of smoothness and a little bit about pivot physics. (or at least my style of physics)
