An object slides along the surface of the earth and slows down because of kinetic friction. if the object alone is considered as the system, the kinetic frictional force must be identified as an external force that decreases the momentum of the system.
a) if both the object and the earth are considered to be the system, is the force of kinetic friction still an external force?
b) can the friction force change the linear momentum of the two body system?
