What is perpetual motion?
Q: What is perpetual motion?
A: Perpetual motion refers to a movement that continues forever once started without additional energy added.
Q: Can perpetual motion machines exist?
A: No, perpetual motion machines cannot exist because they would violate the law of conservation of energy.
Q: What does the law of conservation of energy state?
A: The law of conservation of energy states that energy cannot be created or destroyed but can only be transformed from one form to another.
Q: What is the interest in perpetual motion machines?
A: Perpetual motion machines have interested inventors for a long time, even though it has been shown that such a machine cannot exist.
Q: How have perpetual motion machines been classified?
A: Perpetual motion machines have been classified into different types, each of which breaks a different law of thermodynamics.
Q: Why do people still try to build perpetual motion machines?
A: People still try to build perpetual motion machines because they are fascinated by the idea of an endless source of energy.
Q: What is the problem with perpetual motion machines?
A: The problem with perpetual motion machines is that they violate the law of conservation of energy, which is a fundamental principle of physics.
