The discussion explores the potential of using tire rotation to generate electricity and extend the range of electric cars. Participants reference regenerative braking as a related concept, where energy is recaptured during braking. The feasibility of harnessing energy from tire movement remains uncertain, with various technical and practical challenges highlighted. The conversation emphasizes the need for innovative solutions to improve electric vehicle efficiency. Overall, the idea presents an intriguing avenue for enhancing electric vehicle technology.
I already posted a similar thread a while ago, but this time I want to focus exclusively on one single point that is still not clear to me.
I just came across this problem again in Modern Classical Mechanics by Helliwell and Sahakian. Their setup is exactly identical to the one that Taylor uses in Classical Mechanics: a rocket has mass m and velocity v at time t. At time ##t+\Delta t## it has (according to the textbooks) velocity ##v + \Delta v## and mass ##m+\Delta m##. Why not ##m -...
