Maybe this gravity demo will help ?

I’m making a 2D platformer (How do you make a Ball or Sprite 'jump'?)

You can't loop to wait. Here is a relevant project from the defunct Scott Ferguson graphics library: https://groups.google.com/g/app-inventor-developers-library/c/aPctM06_Kuo GravityExercise.aia (4.4 KB) [blocks] (My attempts at flinging with a trackball were mostly futile, but I got a bounce or two out of it.)

There is a bounce block that is useful when you hit an edge.

It takes all the work off of bouncing off an edge.
