### A moving pendulum illustrates the change from potential energy to what?

A moving pendulum illustrates the change from potential energy to kinetic energy. In the process of its motion from its mean position to either of its extreme positions, the total energy remains constant, thus following the Law Of Conservation Of Energy.

### What law of the scientific rule states that energy cannot be created or destroyed?

The law of Conversation of Energy

### What law says in chemical change energy is neither created or destroyed?

Scientists call this law the law of conservation of matter

### Law that states that energy cannot be created or destroyed?

The law of Conservation of Energy. Actually, that law has been superceded now by a slightly different one. Recently (maybe 100 years ago) it was learned that energy can become mass and mass can become energy. So the law had to be modified to say that the total combination of mass and energy can't be created or destroyed.

### Will law of energy conservation apply to simple pendulum?

Yes, The total amount of energy will always be constant. That is that GPE + KE = Total Energy - external forces(friction, sound, heat, etc.)

### Balanced chemical equations demonstrate?

the law of conservation of mass.

### Of thermodynamics is a restatement of the law of conservation?

The 1st Law of thermodynamics is a restatement of the law of conservation of energy.

### What states have energy laws that state that energy can not be created or destroyed?

Law of conservation of energy. Energy can't be created or destroyed is the basic statement of the law of conservation of energy.

### Why the law of conservation of energy can mean that you do not have unlimited sources of energy?

That is because the law of conservation of energy states that you can not create new energy.

heat

### According to the law of conservation of mechanical energy if the only force acting on this pendulum is gravity the total energy of the system is .?

Conservation of mechanical energy means that the total mechanical energy doesn't increase or decrease over time.Note that in real systems, some mechanical will always be lost due to friction.
