I think the chain just wouldn't ever move at constant speed. It would be slowing the whole time as the energy stored in the battery is spent in the resistor.

- kayson 4y agoThat's a good point, but I think for an approximation, we can assume its constant. It gets up to speed very fast and then stops equally fast. Presumably this is because of the constant-torque spring they're using? In any case, by observation it does seem that for most of the time, the speed isn't changing.
