"work" to change velocity is proportional to the square of the change in velocity, proportional to mass, and independent of gearing.

- falcolas 11y ago"work" also involves the total velocity change, which means that the trip to employment results in the same amount of total work, regardless of the number of stops made, and which over the total of a day results in 0 work being completed (assuming a round trip from home to the place of employment). Perhaps the physics definition of "work" isn't quite the right one to use?
- talaketu 11y agoA regenerative braking system might make cyclists happier to stop, it's true.
- Nadya 11y agoThe physical "work" of trying to take off uphill in 7th gear is a lot more effort than taking off in 1st gear on a 7 gear bike.
- zimpenfish 11y agoI'd suggest testing that theory by moving off from a standstill in various gears and seeing how much "work" each one takes.
