The billiard ball atom model was proposed by John Dalton.

The correct answer is: The ball-and-stick model.
A theory. Its the Atom Theory. The old theory used to be that an atom was just like a billiard ball.

The word is spelled billiard, just as you spelled it. The billiard ball rolled smoothly to the corner pocket.
A billiard ball.
The billiard ball was not discovered but evolved. The evolution has been described as taking place in both France and in Italy. Both Italy and France had billiard tables, and of course, billiard balls, in the 1400's.
The answer is rather simple. Even though a billiard ball is smooth, when it rolls it imparts some of its kinetic energy to the felt covering of the table. That is, the felt heats up a bit as the ball slows down.
Dalton's atomic model is one of the fundamentals of physics and chemistry. John Dalton named this model after himself.
