When you hit a straight shot without spinyour paddle contacts the ball and pushes it away from you in the direction of your swing. Topspin is when the ball spins away from you with the bottom of the ball traveling up and over the top. To add topspinstart your swing lower and contact the ball on your paddle’s upward movement.

HOW BALL MILL WORKS? energosteel

Does ball spin affect trajectory or bounce direction

Ball spin has no effect as far as I can tell. It is also very hard to get a good spin on the ball in the first placeand if it does have a lot of spin it probably wasn't hit as intended.
