Your easing and physics are way off.

If you want to make good looking smoke and other effects you have to use particles.

Your frame rate is also too low.

You should be animating at anywhere from 12-24 fps.

Well, first just work on phsics and how the bouncing works and the weight effects. Then practic particles and dicipation of smoke. Once you put them together you get a smoke bomb.

Unless it got windy the ball don't seems to follow the rules of gravity.

More ease in the smoke.

First you need to learn basic physics, such as bouncing, before you even attempt to make something like smoke.
