ANSWER GETS MEDAL! How is efficiency affected by friction?

OpenStudy (anonymous):

When two objects rub together friction is formed which creates heat. When heat is created in a system, energy is lost due to the fact that it changes to form heat. The more friction there is in a system, the less efficient that the system is because efficiency is what percentage of energy that comes out of the system from what is put in to it.
