This is an accidental discovery. Here I used the Algodoo 2D physics simulator to model a faster than the board cart (featured in the Varitasium video $10,000 scientific bet video). This cart has a mass attached to the outside edge of the big wheel to produce a pendulum affect. Gravity pulls on the mass causing the cart to accelerate with sufficient force to conserve some of the energy and add it to the next swing, thus the cart evidently accelerates using only the force of gravity! A discovery worth further investigation on better simulation software! This is a very low friction simulation with air resistance turned off.

Bonjour MoRo,


en regardant attentivement la vidéo, j'ai l'impression que le véhicule va de plus en plus à gauche et de moins en moins à droite, mais couvre la même distance..., pouvez-vous confirmer ?


À bientôt

Bonjour À bientôt,


le chariot va accélérer dans les deux sens !  Il continuera à accélérer dans n'importe quelle direction une fois que le pendule aura dépassé le sommet du cercle !  Je le montrerai en vidéo dès que possible, et le posterai ici.


the cart will accelerate in both directions! It will continue accelerating in whichever direction it is going once the pendulum passes the top of the circle! I will show it in video as soon as I can, and post it here.
