Question

how does the law of conservation of energy apply to machines

Answer 1

Explanation:

When the source of energy is removed,machine will stop however, the machine will eventually stop. Thisprinciple is referred to as

the law of energy conservation.

Answer 2

According,to the law of conservation of energy,the amount of energy in a closed system always stay constant. So,the amount of work output and other transformed energy is equal to the amount of energy inputs. In this way,the conservation of energy is fulfilled by the machines.
