Re: X and Y Velocity
Okay, well, just think of velocity as speed. X Velocity is the speed going horizontally (left and right), and Y Velocity is the speed going vertically (up and down).
Right, so imagine you have a script like this:
Now, if we add velocity:
It changes the speed at which the sprite is moving to the left and right. It always changes x by the variable "X Velocity," which is controlled by the left and right arrow keys.
Of course, that doesn't include slowing down if you aren't pressing anything, but that's a bit more advanced...
For more information, see Velocity on the Scratch Wiki.

Re: X and Y Velocity
Wow, WeirdF. That was an awesome response. I've been using velocity for some time, and that was great. But may I suggest: Set X VELOCITY to X VELOCITY to X VELOCITY (*) 0.98 for friction. K?

That's really only necessary if there are areas with varying friction, but good point regardless.
