Answer 1

✨Answer✨

• Friction produces a lot of heat in various parts of the machinery and this leads to wastage of energy as heat.
• Opposes motion, hence more energy is needed to overcome friction.
• Noise production in machines is irritating as well as leads to energy loss.

Answer 2

Disadvantages of Friction are as follows :

• Due to friction, there is wear & tear of an object. Lubrication is used to allow the parts to move easier & to prevent wear & tear. Greasing is done in the moving parts of bicycle, machines, gadgets and vehicles.
• Friction produces heat. For example, machine parts that move produces heat. This heat which is generated due to friction can damage certain parts of the machines if the machine is not carefully controlled.
• In the roller skating, rolling shoes & smooth surface are used to minimize friction. Wooden floor used for cycling.
• It decreases the life of moving parts of machines and vehicles.
