Differentiate between types and forms of energy​

Types of energy refer to different types of potential (chemical, nuclear, etc.) and kinetic (heat, sound, etc.) energy. Energy can change from one form to another. A good example is a Roller Coaster. When it is on its way up, it is using kinetic energy since the energy is in motion. When it reaches the top it has potential (or stored) energy. Potential energy comes in forms that are stored, including Chemical, Gravitational and Nuclear. Kinetic energy forms are doing work - Like electrical, heat, light, motion and sound. Difference between them both are, Potential energy can be stored and Kinetic energy is already doing work and can't be stored.

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
