The law of conservation of energy states that...?

-the total is constant. One common phrasing of this is that energy cannot be created or destroyed.

The second law of thermodynamics is a general principle which places constraints upon the direction of heat transfer and the attainable efficiencies of heat engines. In so doing, it goes beyond the limitations imposed by the first law of thermodynamics. It's implications may be visualized in terms of the waterfall analogy. It's fundamental principle is entropy: In any cyclic process the entropy will either increase or remain the same.\n\nBasically, creationists believe in that the 2nd Law defines intention. An ordered process. But it has been disproven 100 years ago.

the second law of thermodynamics. it states that a body cannot extract energy from a lower energy body to a higher energy body, in a simplistic sense. the body cannot extract energy from a depleted energy reserve to do work, the physical effects of which are usually of higher energy levels.

The second law of thermodynamics states that "the entropy of an isolated system not at thermal equilibrium will tend to increase over time, approaching a maximum value."\n\nThe Second Law is a statistical law and thus applicable only to macroscopic systems. When one part of an isolated system interacts with another part, energy tends to distribute equally among the accessible energy states of the system. As a result, the system tends to approach thermal equilibrium, at which point the entropy is at a maximum and the free energy is zero.

Not always. If the object is in motion, then no. The total energy, aka total mechanical energy is always constant due to the Law of Conservation and Energy. It depends on the problem. Certainly,if you know the total mechanical energy in the system than you can find a variable for the kinetic energy or gravitational potential energy,assuming you given other variables.

If someone does then they haven't told me.  As for self sustaining energy, the second law of thermodynamics forbids any such thing from existing.

it *is* Bernoullis principle.  Think of pressure as a form of potential energy and velocity as kinetic energy.  The total energy must remain constant so, if one increases, the other must decrease.\n\n\nDoug

The field of thermodynamics has defined that you can never get more energy out of a motor than it takes to run it.  It's called the law of the conservation of energy, and the efficiencies possible by engines have been identified by what is called the Carnot cycle.  You will always lose energy, due to the constant increase in "entropy" (a measure of useful work possible in a system) in all spontaneous processes.\n\nWhat you describe is a perpetual motion machine.  Due to the inefficiency of the motor, you will lose useable energy (ie there will be an increase in entropy) such that the motor wil slow down continually until it eventually comes to a stop.\n\nI had this same idea when I was a kid until my dad set me straight.  Then I was very sad.

First Law of Thermodynamics: Energy can be changed from one form to another, but it cannot be created or destroyed. \n\n"You can't win."  Because you can never get more energy than you start with.\n\nThe Second Law of Thermodynamics states that "in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state." \n\n"You can't break even."  Because you lose potential energy.  It changes to heat.

The total amount of energy in a closed system remains constant.\nThis, however, was found to be untrue. It was later substituted for the conservation of Mass-Energy.\nThis was also disproven. In fact, if a tiny bit of energy is "borrowed" from nothing for a really short amount of time, it can create mass according to the equation:\nE*t = h/(2*pi) = 1.06*10^-34 Js\nOf course, for our pruposes, the conservation of energy works.

The potential energy stays the same.

Sounds like its something related to 'entropy' otherwise known as the 2nd Law of Thermodynamics. "What can go wrong, must go wrong" as Murphy would say.

Energy can go from place A to place B (think about sound and light)\nEnergy can go from object A to object B (think about a collision)\n\nTh

Scientifically speaking - Energy is conserved - it can't be made and it can't be destroyed - so technically energy is exchanged.  Like when you put you're cold hands on a hot cup of hot chocolate - the Heat from the cup is transferred to your hands - in a roundabout way.\n\nHowever - Religiously speaking - that last bit of energy conserved within the body could be also known as ur Soul - and that is the last thing that is present before the outer aspect of the body is discarded.

The first answer is correct.  Energy.  Energy is defined as force applied through a distance.  This specific type of energy is known as kinetic energy (energy of motion).  Energy is measured in joules, or J.  E = F x D, so if you applied 50 Newtons and the object moved 1 metre, you would have expended 50 joules.

true... this is a written law.. the faraday's law..in electromagnetics..

law of conservation of energy\nany gas that is compressed will 'lose' its heat energy to the ambient temperature in the process (ie a refrigerator). in the specific example the gas (1 cm3 at 70F )is at room temperature until its expanded to lets say 1000 cm3, now 70F is spread out 1000x the area,(as is the gas in the can) the more the 70F is expanded the 'colder' it gets (much like the universe or a car tire, but its all relative)
