 * Mechanical Energy **

__Mechanical Energy__- the ability to do work.

The more mechanical energy you have the more work you are able to do. When the mechanical energy of an object is applied to another object, it causes the other object to be displaced.This energy is associated with the position and motion of the object. Potential energy has to do with position. It is stored whenever something moves in the opposite direction to a force acting on it (Potential14). Kinetic energy has to do with motion. The faster an object moves, the more mass it has, making it have more kinetic energy (Movement 16). So the more potential energy and kinetic energy you have the more mechanical energy you have. To find mechanical energy, the equation is:

Mechanical=Potential+Kinetic

Mechanical energy is like throwing a football. The higher the football the greater the potential energy. The faster the football moves, the greater your kinetic energy. You add the potential and kinetic energy to find the mechanical energy of the football (Jones 154). .


 * Other forms of Energy **

__Electrical Energy__ - the energy of electrical charges (Jones 157)

Electrical energy can be either potential or kinetic energy depending on whether the charges are moving or stored. Electrical Energy is the result from electric forces between charged particles (Berger 29). An example of electrical energy is lightning. Lightning is just electrical charges. The electrical charges in the lightning carry electrical energy in them.You also use electrical energy when you use batteries.

__Nuclear Energy__- the energy stored in the nucleus of an atom (Jones 158)

Nuclear energy is a type of potential energy that is released in a nuclear reaction.This kind of energy produces electricity during a nuclear reaction. Nuclear energy can be made naturally or man-made. The sun makes light because of nuclear reactions. That is natural nuclear energy. Man-made nuclear energy is made in nuclear powerplants to provide electricity for many towns and cities (ThinkQuest).

__Thermal Energy__-the total potential and kinetic energy of the particles in an object.

Heat is simply the kinetic energy of atoms and molecules that make up the object. The hotter the object is, the faster it's particles are moving (Heat 20).The faster the particles move, the more kinetic energy it has making it have more thermal energy too. Thermal Energy flows because of the shaking of the particles back and forth ( Berger 43). An example of thermal energy is lava. Lava has a great amount of thermal energy because the particles are moving fast making it have more kenetic energy. This makes it have more thermal energy also.Ice cream is another example. The warm air speeds up the particles in the ice cream. Like lava, there is more kentic energy making it have more thermal energy too(Jones 156).

__Electromagnetic Energy__-the energy of light and other radiation.

Electromagnetic energy travels in waves.These waves have electrical and magnetic properties. Electromagnetic waves are waves of electrical and magnetic force that are created by vibration of electrons. The waves travel at the speed of light (Waves). Some examples of this form of energy is the microwave and x-rays that are are used by doctors (Jones 158).The suns waves are electromagnetic waves. Without the energy from the waves that reach the Earth threw space, the Earth would have no plant or animals on the planet (Sun 48).

__Chemical Energy__- the potential energy stored in the chemical bonds that hold chemical compounds together

Chemical compounds are made up of atoms and molecules.Bonds between these atoms and molecules have chemical energy.When bonds of chemical compounds break ,new chemical compounds are formed (Jones 157). When atoms combine to form molecules energy may be released ( Berger 18).Things, such as plants, get energy from the sunlight and store it as chemical potential energy (Food 52). Chemical energy is stored in all foods. When food is burned, chemical energy is released (Food 52). It is also in matches and cells in your body (Jones 157).
