Is friction advantageous or disadvantageous in the field of games& sports? give your comments with an example.

Answer

Friction is usually called a necessary evil. It means it is essential in the life and we will not able do any work without it.

Advantages of friction	Disadvantages of friction
Keeps the object in position: by friction, the object can be placed at the position and shaped.	Wear and tear of object: Due to friction, there is wear and tear of objects. Lubrication is used to allow the parts to move easier, moreover, prevents wear and tear.
Helps to move: Frictional forces helps to move the object by friction. It helps in running walking. With friction of feet/ shoes on the surface, help to speed. Frictional forces help to move the object in the speed. For example, spikes are used by the athletes to run fast.	Wastage of energy: Excess of friction means extra energy, thus energy is being wasted.
Hold or grip an object: With the help of friction, the ridges of the skin of our fingers and our palm enable us to grab and hold the object for example in badminton the player use grip to hold it.	Slow down the speed: In the roller skating, rolling shoes and smooth surface are used to minimize friction.
Produce heat: The law of conservation of energy states that the amount of energy remains constant. Thus, the energy that is lost due to friction in trying to move an object is really turned into heat energy.	Makes movement difficult: Friction can make the job difficult when has to move the object. Excess friction can make a difficult to slide a box across a floor, walk through deep snow.
