Introduction to Energy

Energy is defined as the ability to produce change or do work. What is Energy? Energy is defined as the ability to produce change or do work.

How we recognize energy Energy produces light Energy produces heat Energy produces motion Energy produces sound Energy produces growth Energy powers technology

Two main kinds of energy Kinetic energy—energy of motion—the motion of waves, electrons, atoms, molecules, substances, and objects Potential—stored energy and the energy of position

Kinds of Potential Energy Chemical Energy Energy stored in bonds of atoms and molecules

Kinds of Potential Energy Stored Mechanical Energy Energy stored in objects by the application of force

Kinds of Potential Energy Nuclear Energy Energy stored in nucleus of an atom Can be released by fission (splitting the atom—used for nuclear power) or fusion (two small atoms come together to make one big atom—happens in stars)

Kinds of Potential Energy Gravitational Energy Energy of position or place

Kinds of Kinetic Energy Electrical Energy Energy of movement of electrons

Kinds of Kinetic Energy Radiant Energy Electromagnetic energy that travels in transverse waves

Kinds of Kinetic Energy Thermal Energy AKA heat, is the internal energy in substances-vibrations and movements of atoms in a substance.

Kinds of Kinetic Energy Motion (Mechanical) The movement of objects from one place to another.

Kinds of Kinetic Energy Sound The movement of energy through substances in longitudinal waves.
