Question

list out the materials required and explain an activity to show that there is no effect of area of contact of the object on frictional force​

Answer 1

Answer:

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.[2] There are several types of friction:

Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into static friction ("stiction") between non-moving surfaces, and kinetic friction between moving surfaces. With the exception of atomic or molecular friction, dry friction generally arises from the interaction of surface features, known as asperities

Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other.[3][4]
