Energy Forms and Transformations Objective: Examine the various forms of energy in order to identify and describe specific energy transformations.
Energy the “stuff” that makes “stuff do stuff” OR the ability to do work. (W=F x D) (F=force d=distance)
Types (kinds) of Energy KE (kinetic energy) PE (potential energy) There are 2 different TYPES of energy, but there are 6 FORMS of Energy. Let’s see how each of these forms are different!
Forms of energy Mechanical Heat/Thermal Chemical Electromagnetic Nuclear Electrical
Mechanical Energy Energy of motion or position Moving school bus, frog leaping, sound, wind, waterfall, compressed spring Can be KE or PE
Heat/Thermal Energy The internal motion of an objects atoms and molecules. Measured by temperature. The faster particles move, the more thermal energy they have. KE only When energy changes from one form to another, a small amount of thermal energy is always released!
Chemical Energy Energy stored by chemical bonds in an object. When bonds are broken energy is released. PE only Match, gasoline, food, coal, wood, cells in your body
Electromagnetic Energy energy that travels in waves; have electrical and magnetic properties Light, Magnetism, X-Rays, Radio waves, microwaves, ultraviolet and infrared radiation KE
Nuclear Energy Energy stored in center (nucleus) of an atom When an atom’s nucleus split apart (fission) this energy is released Fusion (forming) when several nuclei join The sun Most powerful PE only
Electrical Energy Moving electrical charges. Electricity from batteries, power lines, lightning, static shock KE
