    I am running into a problem where when a physics enabled ball is going slowly it doesn't bounce off objects correctly. I have made a video to illustrate the problem



    Basically, the ball should run into the stationary ball and the stationary one should bounce off. This works when the speed is fast enough, but below a threshold they both just start moving together, which looks weird.

    Whats going with this, and how can I make it react properly?

    Experiment details (same for both objects):
    Mass: 1
    Drag: 0
    Angular Drag: 0
    Use gravity: false
    Physics material:
    Dynamic friction: 0
    Static friction: 0
    Bounciness: 1

    You are fantastic. I didn't even know there was a bounce threshold, but that was it.
