How to stop moving the cube upwards against the ball(player) ?

As i am about to drop the ball (player) on the cube, the cube moves upwards against the ball in the game view and it disappears. Rather the ball is being dropped on the cube in the scene view. Why is this happening? Please help.

It’s hard to help without seeing your code or some pictures, but one potential problem could be that your ball is parent to the Main Camera, making it seem as though the cube is rising when in reality the ball is falling. Check your hierarchy to see where your camera is.
