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.
