Re: [RC] [RC] Physics - ll cole

"The gears allow force to be applied in a comfortable range (for the rider) to move the bike, e.g. you may not be able to climb a hill in 6th gear you can climb in 1 st gear. HOWEVER, the bike is not adding energy. There is no free lunch supplied by Mother Nature. You do just as much work in 1st gear as you do in 6th gear. The force resulting force - while it might be less is applied over a longer distance."

 

Thank you for saying this so much better than I could.

It all boils down to energy is always conserved. To move a given mass a given distance requires a fixed amount of energy.
