Anyways looks like my sleep after the nightshift isn't happening so I might ask some questions just now....

I didn't do physics at school past standard grade and just passed that and no more just using common sence and pretty much no study other than knowing speed=distance/time...lol. I was good with maths though which helped some....but im a REAL newbie at this...

To maintain a certain velocity of anything, it is always accelerating ?
No...a constant velocity means NO acceleration. Acceleration causes a change in velocity.

I am very confused with the two. Velocity to me has always been pretty much completely interchangable with speed - is that correct ?

I have always seen it as the faster the speed and the more heavy the weight of an object hitting another object, the more it the second object moves. But with F=ma newtons second law, it confuses me....because it is not the velocity but the acceleration and like you said 'a constant velocity (speed I think...) means no acceleration which results in no force via the equation. If two rocks in space(just to get rid of other forces at the moment) are traveling at a speed or velocity but not accelerating, it appears to me that their should be force applied on to the other. Kinda like if you hit a cue ball in pool and its slowing down to a crawl where it seems to be deaccelerating, it will still give force to the object ball. Im just very confused and I know Im not right here but this is the way im thinking....where am I going wrong ?
