This Question is Closed

yes it does..as by adding weight the amount of normal reaction acting increases and hence frictional force also increases..as \[F =\mu N\] and N is Directly proportional to weight..

Normal reaction..the reaction which is acting on a body having weight..

The increase of weight only results in the increase of the frictional force not the coef. of friction for this case. Note that the u is a constant.

does it not increase because the coefficient of friction is a ratio? that's the definition i have for coefficient of friction

The ratio is derived from the observed frictional force and normal force. For normal dry friction this ratio remains constant.

so since its constant it does not change

and what do you mean by normal dry friction?

This is between to surfaces with no lubricant in between them.
