If the object were to have infinite energy stores in order to pay this friction toll and maintain its path of motion unaltered, it would violate both the First and Second Laws of Thermodynamics. Thus over time as the object travels it loses all of its kinetic energy attempting to overcome friction and eventually it becomes motionless. Overcoming this friction force requires giving up some kinetic energy. Whenever two objects are in contact, there is friction between them. ![]() One of the greatest obstacles facing any object in motion that wishes to remain in motion is friction. you cannot get more energy out of a closed system than you put in. An efficiency of 1 means that all of the energy put into the system is spat out as useful energy, with no loss through waste processes. Efficiency is, simply put, a ratio of the useful output energy to total input energy. The Laws of Thermodynamics thus place a limit on the efficiency of a heat engine. Any change in the internal energy of a closed system is equal to the amount of heat supplied to the system, minus the amount of work done by the system on its surroundings. Within an isolated system the total energy is constant. The First Law of Thermodynamics is that of "conservation of matter and energy," which states that matter and energy cannot be created or destroyed. So that on balance the entropy, or disorder, of the Universe actually increases. If one does this, one sees that the decrease in entropy that comes along with forming a human being is accompanied by an enormous increase in entropy from the radiation of energy from the sun (along with other increases and decreases). This means that the entropy change of every process that went into making life on Earth must be taken into account. ![]() However, the Second Law of Thermodynamics applies to closed systems. Evolution from tiny microbes (somewhat ordered) to complex human beings (very ordered) seems to be a clear example of order emerging from chaos. Life on Earth, for example, is an obvious and frequently stated one. There are many physical phenomena that are often misquoted as violating The Second Law of Thermodynamics, the idea that disorder must increase over time. That is to say, if we measure the entropy or disorder of a system at two distinct times, the time at which the system is in greater disorder is the later time. Since entropy must never decrease, the Second Law of Thermodynamics can be interpreted as an indicator of the direction of flow of time. And T is the temperature, so that the change in entropy is always greater than or equal to zero.
