Burning matter produces what kind of energy

It takes energy to get an object moving, and energy is released when an object slows down. Wind is an example of motion energy. A dramatic example of motion energy is a car crash—a car comes to a total stop and releases all of its motion energy at once in an uncontrolled instant.

Sound is produced when a force causes an object or substance to vibrate. The energy is transferred through the substance in a wave. Typically, the energy in sound is smaller than in other forms of energy. Electrical energy is delivered by tiny charged particles called electrons, typically moving through a wire.

Lightning is an example of electrical energy in nature. What is energy? Forms of energy. Units and calculators. Use of energy. Energy and the environment. Also in What is energy?

Nonrenewable sources. Oil and petroleum products. Diesel fuel. Heating oil. Nuclear potential energy, or nuclear energy, is the energy found in the nuclei of atoms. The protons in a nucleus exert very strong repulsive forces on each other due to their positive charge.

In turn, the neutrons that make up a nucleus exert very strong forces on the protons to keep them from flying apart.

Splitting a large nucleus nuclear fission or combining small nuclei into a larger nucleus nuclear fusion overcomes these strong forces and releases energy as a result. The energy released by an individual nucleus is very small, but huge numbers of nuclei can release huge amounts of energy as evidenced by the energy produced by nuclear reactors fission and by the sun nuclear fusion.

Thermal energy is due to the movement, and the kinetic energy associated with this movement, of molecules that make up an object or substance. All objects possess thermal energy even cold ones since they have a temperature above absolute zero. Evidence of thermal energy can be detected by measuring the temperature of an object. Although technically incorrect, the word heat is often used to mean thermal energy. In strict scientific terms, there is a distinct difference between the two.

Thermal energy pertains to the kinetic energy of the molecules within an object. Heat is the transfer of energy between two objects. Wherever possible, we have tried to remain true to these distinctions.

However, since heat is the more familiar term we often use that to facilitate understanding. Sound, mechanical motion, heat, and light are not easily classified as kinetic and potential energy. They are evidence of energy. Movement , sound , heat , and light provide evidence that energy is present and being used. Sound is produced when we strike something. But does sound do work? Yes, sound can move things.

Sound waves move the tiny bones in your ear and shake windows when a loud truck passes by. Sound waves are also evident in the vibrations from playing a radio. Our body is working even when it appears to be still. Breathing, blinking, and digesting food all require energy.

For us to do these activities, our bodies burn the energy in food. Burning Plasma. The Sun is an enormous ball of burning plasma involving a fusion reaction known as the proton-proton chain. In the core of the Sun, self-heating of hydrogen ions protons sustains the temperature of the ions above the level required for fusion to occur. The Sun has been burning hydrogen for 4. To reach fusion-relevant temperatures, the ITER tokamak will heat plasmas using three methods.

Ohmic heating involves heat generated by resistance to the plasma current, much like how the coils in a toaster heat up. Neutral particle beam injection involves heating the plasma by injecting high-energy particles into the tokamak.
