Answer 1

$\huge\mathcal{\red {\underline {\overline {\mid {\pink {Answer}}\mid}}}}$

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.

Answer 2

Answer:

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.

Static friction is a force that keeps an object at rest. ... The friction experienced when individuals try to move a stationary object on a surface, without actually triggering any relative motion between the body and the surface which it is on.

The law of reflection refers to the reflection of light-rays off smooth conducting surfaces, such as polished metal or metal-coated glass mirrors. ... The angle of reflection is equal to the angle of incidence.
