Question

write advantages and disadvantages of friction explain​

Answer 1

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.

Answer 2

$\huge \frak \green{answer}$

$\frak \blue{advantages}$

Friction helps us to walk on the ground.

We are able to write on the board due to friction.

Friction helps in stopping a car by applying the brakes.

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

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

$\frak \blue{disadvantages}$

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.
