What are disadvantages and advantages of the friction.answer in200words
subject science class 9th ​

Answer 1

Answer:

Explanation:

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.
