Friction is the resistance to motion of one object moving relative to another. There are several types of friction. Some advantages and disadvantages of Friction are given below.

$\: \: \: \: \: \: \: \: \: \: \:$

➡ Advantages of Friction:

• Friction is responsible for many types of motion

• It helps us walk on the ground

• Brakes in a car make use of friction to stop the car

• Asteroids are burnt in the atmosphere before reaching Earth due to friction.

• It helps in the generation of heat when we rub our hands.

➡ Disadvantages of Friction:

• Friction produces unnecessary heat leading to the wastage of energy.

• The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects.

• Forest fires are caused due to the friction between tree branches.

• A lot of money goes into preventing friction and the usual wear and tear caused by it by using techniques like greasing and oiling.
