Is this something like Dead and Heavy ball ?
As a beginner-level player I can say --> quick === fast
early and long push <====== meet the ball early as it rises up, lift and push ball to land on white-base line on the other side.
early/ peak ( high-point) / late contact<---- you can meet the ball at these height-levels and get different effects.
short/mid/long push <------- if you want to play a very safe push, push short with a little lift. You will use the momentum and spin of the incoming ball to send it back "somewhere" safe on the table, usually the centre. If you mistake the spin ---> ball will either rise up/ brush the net/ go left/go right but will almost always stay on the table but close to the net.
I'm just a beginner so others can explain a lot more about "quick and fast push"
