spate advintage and this advantage of friction
Answers
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:
I hope it helps you friend please follow me
Explanation:
Disadvantages of friction:
It always resists the motion, so extra energy is required to overcome it.
It causes wear and tear of machines.
It decreases the life expectancy of moving parts of vehicles.
Since friction is very useful in some cases while harmful in some cases, friction is called a necessary evil.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.Friction's advantages include:
Being able to walk across a surface without slipping. This is static friction.
Writing on a piece of paper with a pencil or a pen. This is. sliding friction. * Driving a car across the road surface. This is. rolling friction. * Jumping out of an airplane with a parachute. This is.
