So a rolling mass that's say 3 tons is going to be rolling at a higher speed (3 times?) down a slope compared to a 1 ton rolling mass?
Yes - if the aerodynamic efficiency, and the rolling resistance of the two is the same!
As the two get moving the 3x heavier mass is trading it's 3x gravitational potential energy to produce velocity, and it does so at the same rate as the 1x mass - the rate of acceleration remains the same. However when the 1x mass is trading all of it's gravitational energy to maintain the same velocity - it's terminal velocity - the 3x heavier mass is only using 1x gravitational potential energy and the remaining 2x energy continues to accelerate that mass even further - it's terminal velocity is higher.
So humperdinkel wins!
The main point is gravitational acceleration is only uniform in a vacuum - it does not apply in any other context.
Love the video Moto!
