[F8] Volocity

[tongxn]

Hello and sorry for the many questions

Now before I propose this question I dont want to mess volocity up with Gravity or any Attractive force

If I had a cannon which shoots very HEAVY stuff (forexample a BowlingBall whch dont bounce), the BB will eventually fall down.

Picture 1 is a example of GRAVITY
Picture 2 is an example of VOLOCITY

now Im trying to know how to set the VOLOCITY with the GRAVITY, coz gravity alone has a thousand different volocities involved (according to PIc1) while volocity alone has a infinitive number of gravity lines involved.

Now I typed this much of infomation I forgot what the question is.... er..
How can you set volocity of the cannon to shoot the cannonball alone the VOLOCITY circle, however following the GRAVITY line?
I mean I seen complicated Math like this which takes your brain away and dump it in the dump...
