There are a number of different types of energy that include potential energy (or stored energy), kinetic energy (the motion of objects), thermal energy (caused when there is a sharp change in temperature), chemical energy (caused when a substance is transformed through a chemical reaction), nuclear energy (is energy associated with an atomic reaction), mechanical energy (is the sum of potential energy and kinetic energy) and electrical or electromagnetic energy (changes that are caused by the flow of charged ions or electrons through a current).

There are a number of different types of energy that include potential energy (or stored energy), kinetic energy (the motion of objects), thermal energy (caused when there is a sharp change in temperature), chemical energy (caused when a substance is transformed through a chemical reaction), nuclear energy (is energy associated with an atomic reaction), mechanical energy (is the sum of potential energy and kinetic energy) and electrical or electromagnetic energy (changes that are caused by the flow of charged ions or electrons through a current).

The energy in matter can cause the matter to change. For example, if you (the mass) stand still at the street corner waiting for the traffic light to turn red, you have potential energy. The potential energy is the ability to move forward across the street but by standing still, that potential energy is being stored.

Law of Conservation of Energy:

According to the Law of Conservation of Energy, energy is neither created nor destroyed. Rather, energy can only be converted from one form of energy to another form of energy.
