10 Questions
Which law of thermodynamics would a perpetual motion machine violate?
Second law
What is the primary reason why perpetual motion machines are impossible?
They violate the conservation of energy
What processes slowly dissipate the kinetic energy of celestial bodies, making their motion not perpetual?
Solar wind and interstellar medium resistance
Why will machines that extract energy from finite sources not operate indefinitely?
They are driven by the energy stored in the source, which will eventually be exhausted
