The conversion between different states of energy (e.g.potential energy to kinetic energy):

Question

Quizplus · Accepted Answer

Energy conversions are not 100% efficient, meaning some energy is lost in the form of heat. This is known as the Second Law of Thermodynamics. Therefore, choice A is correct. As energy is converted between different states, such as potential energy to kinetic energy, some energy is typically lost as heat due to friction and other factors. This satisfies choice C as well. However, choice B is incorrect as energy conversions are not 100% efficient. Choice D is also incorrect as energy changing from one state to another is a fundamental principle of physics.
