what is fraction and how many parts of friction
Answers
Answer:
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.
Step-by-step explanation:
For every general rule about friction, there are just as many exceptions. For instance, while two rough surfaces (such as sandpaper) rubbing against each other sometimes have more friction, very smoothly polished materials (such as plates of glass) that have been carefully cleaned of all surface particles may actually stick to each other very strongly.

Answer:
A friction is a force which was produced when two objects were physically in contact. There are 4 types of frictions-: 1 Static friction 2 Rolling friction 3 Sliding Friction 4 Fluid friction
