Pong Mechanics

So my question is pretty short ( and maybe even stupid ) :
What are the pong mechanics, when it collides with a paddle? I mean there are many guides on YouTube that just make the pong bounce with some physics material and set its bounciness to 1, but in the classic pong it doesn’t work like that…
Shoud the new velocity of a pong after colliding with paddle depend on :

  1. paddle’s actual velocity?
  2. the point where it hits the paddle ?
    Or maybe something else ?

I’m not sure what you mean by “should”… If you create a game it’s up to you how you want your mechanics to work. There are countless remakes of pong and many of them work entirely different. If you really are interested in the mechanics of the original pong, have you tried google? It gave me this as the first hit.

In the original the ball always moved at the same x-velocity and just had additional y velocity depending on where the ball hits the paddle. I think the most y velocity it could get was the same amount as the x velocity so at most an angle of 45°. Of course this would be the fastest speed it could move at. However the actual horizontal speed is always constant. So yes, the y velocity simply depends on where the ball hits the paddle.
