what is friction. define it
there are how many typed of friction
advantages
disadvantages
how it's made
how to use
what are the things by which we measure it
Examples
define it olso
1.drag
2.fluids
three are how many types of friction
and define all the works
with spefic Examples and etc
don't copy from Google
other wise I will complain you directly by Gmail and etc
ok
good answer will mark as brainlest ook answer
short answer only ok​

Answer 1

Answer:

Defination--Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.

or

the resistance that one surface or object encounters when moving over another.

Types of friction-

,There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest. Fluid friction occurs in fluids, which are liquids or gases.

advantages-

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-

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.
