Every single thing that is in the universe is made up from two things; matter and energy. The three disciplines (rather than agencies) that research these are biology, chemistry and physics.
Atoms are particles of elements, which are things that cannot be broken down any further. Currently, there are 109 known elements but they can combine in numerous different ways and form what are known as compounds. Molecules are the single units that make up compounds.
There are four fundamental types of matter; liquid; solid; gas and plasma.
Potential energy is energy that is stored and kinetic energy is energy that is in use. For example, if you were to drop a stone from the top of the Empire State Building, the stone would possess kinetic energy, which comes from the weight of the stone.
Typical forms of energy that we all familiar with are light, electrical energy, heat and movement.
There is a lot of concern globally about the types of energy that we use because of the effects that it is having on global warming. Because of this there has been, and still is, a lot research in alternative forms of energy that are 'cleaner' and renewable.
