What is the difference between the law of conservation of energy and conserving energy help prevent energy shortages?
The Law of Conservation of Energy says that energy is never created or destroyed, or in other words, it always comes from someplace and goes someplace.For example: with a car, plants (scientists think algae) long ago stored solar energy by converting it to chemical energy in their carbon chains, which we pump out and make into gasoline. Then the engine converts the chemical energy into kinetic (motion) energy. Finally, the brakes convert the kinetic energy into heat. All of the original solar energy that fell on the original plants, long ago, is eventually converted into heat (except for what stays locked up as chemical energy).Energy Conservation is the practice of consuming energy as efficiently as possible (so no more than necessary is used). For example, using a car that goes a long way on a gallon of gasoline (or diesel, or a KWh of electricity or cubic foot of natural gas). Likewise, insulating your home and using a high-efficiency furnace and air conditioner.So, you may wonder, if according to the Law of Conservation, all energy just goes around and around, why is Energy Conservation important?The problem is that, sight now, most of the energy that we use causes a significant amount of pollution as a by-product of putting it into a usable form. The pollution is a big problem. Also, much of the energy that the U.S. uses comes from countries in the "Middle East" that the U.S. wants to have more independence from.
What happens to stored energy?
The energy stays stored as potential energy until it is discharged into another form of energy.
What law states that energy can change form but is never created or destroyed?
It is the Law of Conservation of Energy, aka the First Law of Thermodynamics.The concept of energy is one of the most fundamental concepts of science.This is the first law of thermodynamics and it is worth saying in several ways.(A) Energy is conserved.(That is short and accurate answer but non-scientists are not used to the word "conserved" being used in this way. But, scientists use it to mean "Stays the same" all the time.)(B) Energy can change from one form of energy to another, but energy can not be created or destroyed.(This is a fundamental law of Nature and the first law of thermodynamics, that energy of a closed system can never change. Sometimes it is said that "the total energy of the universe is always the same." )Discussion:Nature provides us with the Law of Conservation of Energy, whichever way you want to say it. It was about 400 years ago that science started to understand energy. At first it was only kinetic energy, the energy of motion, that was observed unchanged.Soon this was expanded to include gravitational potential energy. Later this expanded to other forms such as elastic potential energy, heat energy, chemical energy, nuclear energy, electrical and many other forms, including the famous "mass energy," E=mc2.How grand to know that the first law of thermodynamics says that we will never run out of energy. Alas, the second law says that Entropy is the problem and energy cannot always be used to do work.Aside: There is a big discussion in cosmology now about "dark energy." This should not be confused with the possibility that maybe energy is not conserved. The truth is that cosmologists have no idea what this "dark energy" is and it is not even a sure thing that it is energy.)
What will a car's kinetic energy be if the car's speed triples?
The Kinetic Energy Stays The Same
Explain the role of friction has in the energy transformation of a person skiing downhill?
Friction and air resistance cause some of the mechanical energy of an object to change to thermal energy so the mechanical energy of the object is not destroyed. Rather, it is transformed into thermal energy. the total amount of energy always stays the same. ur welcome. you have to give me 5 bucks.
What states that during any change the amount of energy stays the same?
Law of Conservation of Energy.
How does converting energy from one form to another relate to the Law of Conservation of Energy?
The law of conservation of energy might apply to an energy conversion that you observe in your daily life for example if you have something on the table and you push it or move it with your arm
How does the idea of atoms explain the priciple of conservation of matter?
The idea of atoms explains the conservation of matter. In chemical reactions, the number of atoms stays the same no matter how they are arranged. So, their total mass stays the same.

What is is kinetic energy?
Energy stays Kinetic.
The law of conservation o mass states that the mass of all substance before physical change equals the mass of all substances after the change?
It very nearly stays the same. If you add a proton and an electron to hydrogen you get helium, which is just under double the weight of hydrogen. The missing mass was given off as energy.
What does it mean to say that in any system the total energy score stays the same?
It means that the energy demand stays the same no matter what energy source it is coming from!
What statement stays the mass of the reactants must equal the products?
This is the well-known law of mass conservation.
What happens to the mass when the state changes?
what happens is the mass stays the same because of the law of conservation of mass
Where does the energy in your body go?
enegry does not go any where it always stays in your body.(remember when u have the enery it can pass on to other objects u touch).
In a energy conversion what happens to the total amount of energy?
It stays constant
What stays the same but always changes?
nothing, atoms are always moving.
