Question

does the normal force of an object effect the fricitional force
​

Answer 1

Explanation:

The frictional force, \begin{align*}f_k\end{align*}, is directly proportional to the normal force the two objects press against each other with, \begin{align*}F_N\end{align*}, and also directly proportional to the roughness or stickiness of the surface, called its coefficient of friction
