Question

what is Frictional Force for class 8 NCERT ​

Answer 1

Answer:

Frictional Force refers to the force generated by two surfaces that contacts and slide against each other. These forces are mainly affected by the surface texture and quantity of force requiring them together. The angle and position of the object affect the volume of frictional force.The main reason behind friction between objects appears is due to the forces of attraction, known as adhesion, between the points of contact regions of the surfaces, which are always minutely irregular. Friction arises from shearing these “fused” junctions and from the action of the irregularities of the harder surface tilling across the softer surface.
