Answer:
Energy loss in mechanical machines such as industrial robots and cars since power input is continuously needed to overcome the resistive effects of friction on motion.
Injuries to humans. An example is when you rub any part of your skin against a rough surface at a high enough speed. Even seemingly smooth surfaces can cause injury due to heat generation by friction. An example is when you ride a long steep slide in a water park and you touch the wall of the slide while moving at a very high speed.
Mechanical wear over time since heat generation due to friction can slowly damage a surface. That’s why car brakes get worn over time.
