Hitting the ball away from axis of rotation
Table Tennis Strokes and Technique

Hello!
Inspired by watching some Dyscovery alike films about physics I ask myself:
Is that a case in Table Tennis or not?
My guess/point is that if I hit the ball exactly rectangular to the axis of rotation (or in other words - to the south or north pole) then the ball woud react as is there is no rotation at all.
On the other hand; If I hit the ball closer to its "equator" then the effect off my oponents spin would be the biggest.
I understand that perfect underspined or topspined balls have the axis in a completely wrong way to hit the north/south pole and not miss the table, but there must be some sidespin variatins that can be hit directly to the pole.
Best regards Bojan

Hi Bojan,
This is the principle of why players use the Backhand Sidespin Flick as you are hitting the ball closer to the poles rather than the equator.

Thanks... So every spin can be neutralized with the spin that is rectangular to it.
Side spin is neutralized with top spin or under spin, and vice versa top spin or underspin is neutralized with sidespin...

In theory yes. Practically though, there is always a combination of spins which makes it trickier.

Bojan,by north/south pole you mean the "top and bottom" of the axis of rotation?
Bojan De Reya Posted 6 years ago
Yes - I use the terminology of the Earth's rotation

Then you are right. By hitting the pole you ignore the spin,however,your stroke and your bat must be tilted exactly vertically to the axis.
