Consider two circles of radii R and R/2 with the smaller one rolling inside the bigger circle without slipping. Copernicus' Theorem states a surprising result that a point on the circumference of the small circle traces a straight line segment - a diameter of the big circle, to be precise. The white balls appear to be moving as a circle rolling inside of the lager circle. But what you see is actually not true. This is an optical illusion. The true path of each ball is a straight line.

The models of perpetual motion machines are motorized versions that were built to illustrate how they were supposed to work in the minds of inventors. Using knowledge of the laws of thermodynamics and Newton's laws, students will be asked to study the logic of the invention and answer the question of why these machines cannot actually work\n
