Energy Transformations
3
Energy comes in many forms that are interchangeable and is always conserved in a closed system.
4
Nuclear Energy Energy stored inside the atom Atom: all matter is made up of atoms, which we will study more later in the chemistry unit Energy stored inside the atom Atom: all matter is made up of atoms, which we will study more later in the chemistry unit
5
Kinetic Energy The energy of motion Also known as mechanical energy The energy of motion Also known as mechanical energy
6
Chemical Energy The energy stored in molecules
7
Sound Energy The energy carried by vibrations
8
Thermal Energy The energy an object has as a result of the motion of its molecules Also known as heat energy The energy an object has as a result of the motion of its molecules Also known as heat energy
9
Radiant Energy Energy that travels as electromagnetic waves Most common is light energy
10
Electrical Energy The energy associated with moving electric charges
11
Energy Transformation Equation Changes in energy can be summarized using an energy-transformation equation.
12
Energy Transformation Equation For example,a microwave oven transforms electrical energy into radiant energy (microwaves), which in turn is transformed into thermal energy which cooks the food. Therefore electrical energy light energy heat energy For example,a microwave oven transforms electrical energy into radiant energy (microwaves), which in turn is transformed into thermal energy which cooks the food. Therefore electrical energy light energy heat energy
13
Energy Transformation Technology The microwave is an example of an energy-transformation technology, which is a device used to transform energy for a specific purpose.

Generator System A generator system converts mechanical energy into electrical energy. The key parts of a generator are a turbine, shaft, and the generator itself. Any type of energy that can be used to turn a turbine can be used to generate electrical energy. The mechanical energy turns the turbine and rotates a magnet within a wire coil, causing the charged particles in the wire to move.
