In a machine, parts come into contact with surfaces and decreases the amount of energy that the machine uses to produce work. How does the law of conservation of energy explain this?
a: the parts dont always line up resulting in energy loss
b: the parts rub against surfaces generating friction and resulting in heat
c: only machines with multiple parts have this problem
d: 100% of energy put into the machine results in work
