Conservation of Energy and Momentum
... you slide a brick across a table from x1 to x2 , then the work done by friction equals −µmg|∆x|. But if you slide the brick by wiggling it back and forth for an hour before you finally reach x2 , then the amount of negative work done by friction will be very large. Since friction always opposes the ...
