You should look at the Tiefenbacher pdf on the ITTF website about spin and speed after impact. Also look up speed after impact on wikipedia. Finally Rodney Cross ( University of Sydney ) has done lots of research on how balls impact objects with spin.
After studying these documents you will understand spin and speed after impact a lot better and modify your webpage.
None of the above use tension as a parameter. Try to find how tension is used in an equation that applies to the spin or speed after impact. Tension and tensor are marketing gimmicks to fool ignorant TT players.
What is an impulse? There is the impulse normal to the paddle and one tangential to the paddle. You didn't mention torque.
A question, if friction and the speed of the alone causes spin then what makes one rubber spinnier than another? Don't say tension. Look at Rodney Cross's and the Tiefenbacher documents.
I love playing table tennis (in fact, all racquet sports) and the strategy and science behind them, so I figured I might as well share my knowledge.
