  What Is Energy?

The simplest definition of energy is "the ability to do work". Energy is how things change and move. It's everywhere around us and takes all sorts of forms. It takes energy to cook food, to drive to school, and to jump in the air.

SIX FORM OF ENERGY

THE MOST USED SOURCES OF ENERGY

LINKS

Chemical - Chemical energy comes from atoms and molecules and how they interact. Electrical - Electrical energy is generated by the movement of electrons. Gravitational - Large objects such as the Earth and the Sun create gravity and gravitational energy. Heat - Heat energy is also called thermal energy. It comes from molecules of different temperatures interacting. Light - Light is called radiant energy. The Earth gets a lot of its energy from the light of the Sun. Motion - Anything that is moving has energy. This is also called kinetic energy. Nuclear - Huge amounts of nuclear energy can be generated by splitting atoms. Potential - Potential energy is energy that is stored. One example of this is a spring that is pressed all the way down. Another example is a book sitting high on a shelf.

Moving Electrons and Charges 

 Electricity is related to charges, and both electrons and protons carry a charge. The amount of the charge is the same for each particle, but opposite in sign. Electrons carry a negative charge while protons carry positive charge. The objects around us contain billions and billions of atoms, and each atom contains many protons and electrons. The protons are located in the center of the atom, concentrated in a small area called the nucleus. The electrons are in motion outside of the nucleus in orbitals. The protons are basically trapped inside the nucleus and can't escape the nucleus. As a result, it is moving electrons that are primarily responsible for electricity.
