Question

Describe an activity to understand the nature of friction.​

Answer 1

Answer:

An expirement of natures of frictions

and concepetes of statices frictions :

The nature of the frictinol is force

primarialy when it depends on the compositions of the surfaces . so, we can illustarte this is a simple experiment in the cass of glass . Ordinary

glass tubeing , even its lookes clear and it will usually caryy on an invisible film of dirt . The air also have sooked into the surfaces of the glass. The absorvations of gases by thr solides in this way which is called occlusion or adsorptions.

Am experimental study is conduceted to mesure the static friction which is the coeffictions under constant normal load and and diffrent interfaces coditions .

i hope its help please mark as brinleaste

Answer 2

Suppose a person tries to drag a table full of things on the floor it is difficult to push the table due to the rough surface. If we oil the surface between table and floor, oil covers up the depression between the surfaces; then it gets easier to push the table.

Due to this purpose, greasing of cycle, doors etc. is done. The friction is decreased by greasing & then the motion is smooth
