Friction is responsible in wastage of energy because due to friction different parts of am machine like a water pumping motor wear and tear because excessive heat is produced, this reduces efficiency of a machine.
Due to friction the sole of a shoe is worn out.
BECAUSE OF FRICTION THE GROOVES OF TYRES OF A CAR GET WORN OUT,
