Unity 2D fix physics problem

Hello, I’m developing 2D game where there are 7 balls and 1 player ball. There is a moving block which is “kicking” the balls like foot in a football. There is also a moving box which is preventing balls from getting to the goal area (like a goalkeeper). Player can use swipes to move his ball (white ball in our case). If ball collides with red area (killer), it teleports to the start. If ball collides with finish it also teleports to the start. For moving the player I use AddForce so keep this in mind. The problem is that basic physics doesn’t work properly because balls are not getting any inertia/force from the foot as well as are not bouncing from the walls/floor.

I attached two videos. First video is illustrating what unity scene looks like right now. Second video illustrates what needs to be done.

Your task is to make absolutely the same physics for balls at this project like in the second video. Don’t add score system or any other features, just fix the physics.
