A riseball "doesn't rise"--it drops less than anticipated. There is about a 3 to 6 inch difference between the "anticipated" position of the ball as opposed to the "real" position of the ball.
When the ball is thrown, gravity immediately starts pulling the ball down. The backspin on the ball slightly counteracts the pull of gravity, causing the ball to drop slightly less over the 40-43 feet between the mound and the plate than if it was thrown with "normal" spin.
What happens to a batter is pretty simple--after years (a decade?) of hitting "straight" fast balls, the batter is "tuned" to hit a pitch that drops a particular distance over the 40 feet or so. So, when the pitcher throws a rise, the ball looks to the batter like it "jumps".
The best example of a rise is the 1968 performance of Bob Gibson in the World Series when he struck out 17. Gibson threw a backspin fastball. The batters consistently swung under the ball. You can watch it on ESPN classic. It is amazing.
Golf balls use backspin to increase distance.
The problem with a softball rise is that the spin can be easily identified. A batter can therefore be trained to identify the spin and "stay on top" of the rise. Thus, a pitcher who throws only a good rise can be dominating in high school but a flop in college.

In the beginning there were carts, stage coaches and chariots, all of which had to be pulled by an animal with their feet on the ground. Trains and cars came along and no longer did they have to be pulled.
On the trains of the day, all Porters were men. When planes came along, they were outfitted with beautiful young girls which were lighter than the Porters of the day. These women gave the impression that the plains were actually flying but they were only lighter and a little higher.
Next lesson will be on helicopters.
