Best ResponseYou've already chosen the best response.0yes 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..

Best ResponseYou've already chosen the best response.0Normal reaction..the reaction which is acting on a body having weight..

Best ResponseYou've already chosen the best response.0The 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.

Best ResponseYou've already chosen the best response.0does it not increase because the coefficient of friction is a ratio? that's the definition i have for coefficient of friction

Best ResponseYou've already chosen the best response.0The ratio is derived from the observed frictional force and normal force. For normal dry friction this ratio remains constant.

Best ResponseYou've already chosen the best response.0so since its constant it does not change
