These are examples of friction creating heat energy. https://study.com/academy/lesson/what-is-friction-definition-formula-forces.html (Disadvantages of friction) It wears out different products Example When we wear shoes,soles wear out after some time because of friction Steps of bridges wear out because of friction Ball bearing of machines wear out due to friction Tyres of car wear out after some time due to friction If we make the surfaces smooth by polishing ,then friction will be reduced. Disadvantage definition is - loss or damage especially to reputation, credit, or finances : detriment. Tribology is the study of wear of materials. Friction between our feet and the ground allows our movements like standing, walking and running. In this way some useful energy is wasted as heat energy. Just rub your hands together to create the same effect. The disadvantage of the friction. Your IP: 35.158.77.53 In this way, useful energy is expended as a loss in thermal energy. Share 3. the disadvantages of friction are: 1.when 2 surfaces rub with each other heat is generated.this can be useful as well as disadvantage.for example,say a tailor is stitching clothes. It cannot be used where there is a requirement of slips. Remember. Without friction between the shoes and the ground, you cannot walk properly.
