1) buy index shifter 2) buy new shifter wire 3) remove old shifter wire 4) remove old shifter(may require grip removal) 5) install friction shifter(if needed, install grip) 6) run new shifter cable 7) clamp cable at derailer as the derailer will have gone slack when you removed the old cable, make sure the shifter is in the right position to pull cable when you clamp the new cable in place. Trim & crimp excess cable, go ride your bike. Note:if your bike have integrated brake and shift levers you either have the choice of getting new brake levers as well, or continue to use the old but with the shifters disconnected.
because you pump your brakes to stop a vehicle

Friction converts movement into unusable energy.
converts to heat
Not QUITE true. Friction can convert usable energy in useless (or unusable) energy, but energy itself can't be destroyed.
Then you have to find a set of brake lever shifters that are compatible with your cassette, no of gears ASO.
convert the following series of index number to chain based indices Year 2003 2004 2005 2006 2007 2008 2009 2010 Index number (base 2003) 100 110 125 133 149 139 150 165
Friction is good because it provides traction. Friction is necessary for people to stand, or for vehicles to accelerate or break. Friction can also be used to convert kinetic energy to heat or electrical energy. Friction can be bad because kinetic energy is can be lost to friction.
Friction would be the easiest way.
Thermal energy, commonly known as Heat.
If it's a Standard transmission [Stick shift] you need to put it on Neutral apply Emergency Brake.. there's a Tab on your shifter under the shifter knob and you need to lift it with your Index finger and middle finger to deactivate it.
