If a shape (a cube, say) is moving in one direction and cannot be stopped, and another cube, in the way of this one, is still and cannot be moved, what happens on collision?
I can't answer it myself :/
Well if the second cube is imovable then we can treat it as a barrier that will transfer back all the kenetic engergy forced upon it.
With your definition we could surmise "cannot be stopped" does not exclude the object could not change vectors.
Therefore is simple layman's terms, the first square will will "bounce off" of the second cube.
Also it will continue at the same speed it had before the collision, at an angle equal to but in a reflective direction, in relation to the line of symmetry of the second square.
Or like something.
