what is frictional force write 2 advantages and 2 disadvantages
please answer fast I am in hurry
Answers
Answer:
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 ...
Advantages of friction:
Friction enables us to walk freely.
It helps to support ladder against wall.
It becomes possible to transfer one form of energy to another.
Objects can be piled up without slipping.
Breaks of vehicles work due to friction.
It always resists the motion, so extra energy is required to overcome it ...
Disadvantages of friction:
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.
Forest fires are caused due to friction between branches of trees ...
I hope it will Help ...

Answer:
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
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.
