Question

from time to time, people claim to have invented a machine that will run forever without energy input and develop more energy than it uses (perpetual motion). what is wrong with this claim? multiple choice this violates the law of conservation of energy. energy forms cannot be converted to new forms. if it makes more energy than it uses it would explode. nothing is wrong, it is a great invention.

Explanation:

The law of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another. A machine that runs forever without energy input and produces more energy than it uses would be creating energy, which violates this fundamental law. Energy forms can be converted (e.g., mechanical to electrical), and there's no reason it would explode just for having a supposed energy - gain. Such a machine is impossible according to known physics.

Answer:

This violates the law of conservation of energy.
