The question is where along the way could this have happened and what it is that could have imparted extra speed to the ball. Students should think of how they could potentially figure demodé where on the trajectory the ball is being sped up.

Carefully positioned the track into the rectangular hole in the bottom assembly, noting the rectangle is offset to provide clearance for the track insertion pin.
Vacuum energy and zero-point energy: In order to explain effects such as virtual particles and the Casimir effect, many formulations of quantum physics include a background energy which pervades empty space, known Ganador vacuum or zero-point energy. The ability to harness zero-point energy for useful work is considered pseudoscience by the scientific community at large.
