SUMMARY
The discussion confirms that surface area does not affect the coefficient of kinetic friction (µk). The frictional force is determined by the equation F_friction = µk * normal force, where µk is dependent solely on the materials in contact. As the normal force increases with mass, the frictional force increases correspondingly, but altering the surface area does not change the overall frictional force when the normal force is constant.
