The Joule System – A Definition of Kinetic Energy

In physics, energy is that particular quantifiable property which has to be moved from a source to a closed system or physical system in order to do work on it or to warm it up. Energy is a unique conserved amount; the total law of energy states that energy cannot be created or destroyed, but can only be changed from a state to another state. The amount of energy in any given system can only be changed to a greater amount by means of energy. Since the sun burns up hydrogen and oxygen to produce energy, the earth’s surface receives heat from the sun and the ocean absorbs heat from the sun, the wind blows out wind and the rain water vaporizes. All of these processes occur without any energy being consumed.

Although the sun, wind, ocean and wind are constantly moving, we rarely think of them as working with energy. We notice their effects, such as heat blowing air and precipitation off mountains or into valleys, or as clouds floating over the skies, or as particles made up of molecules moving through space. Energy from stars, outer space and from vacuum cleaner exhausts are all different forms of energy. Each of these sources of energy has a unique way of converting matter to energy useful to humans.

Kinetic energy, which includes elastic potential, is equal to the product of the force of acceleration times the distance that the object is moved with time. Elastic potential is related to the Planck’s constant, which is also referred to as the speed at which anything moves. The value for a system is its potential energy, which is the product of its velocity with time. The speed of light, of course, is much greater than the average kinetic potential of a hammer head on a desk.

Thermal energy, on the other hand, is energy coming from objects that are warmed by physical contact with the surrounding air or heat. We can think of it in terms of the transfer of heat from one form to another. A piece of metal can absorb heat from an oven, for instance, but it cannot release that heat into the air until it becomes malleable. At first glance, the process looks like the conversion of kinetic energy to potential energy. However, there is another thing to consider.

Total energy, which includes all forms of energy, is what we use to describe the total amount of energy that an object can possibly displace in a state called “potential energy.” Potential energy is equal to the electric current flowing through an insulated wire; this can take the form of a battery, an electric motor, a microwave, etc. The amount of energy in the battery will decrease as the battery discharges, because it has been converted from chemical energy to electrical energy. This is why the battery is referred to as “solar” because it uses the sun to convert sunlight into electrical energy, and then stores that energy in a battery.

The way that you define “kinetic energy” will depend on your knowledge of how different objects move. You can use the joule system to figure out what happens to objects when they are moved by an accelerated current. This works because the more current that flows through a wire, the greater the amount of energy that is stored in the wire. It is this energy that is used to power tools, electric cars, and other electrical devices. Understanding how the joule system works, can help you understand how to store energy so that you can use it to do work (in the battery, for instance), or you can simply figure out how the electric car moves.
