Energy Forms and Transformations Objective Examine the various
Energy Forms and Transformations Objective: Examine the various forms of energy in order to identify and describe specific energy transformations.
DIRECTIONS: Use the information contained on the following slides to complete your “Energy Concept Web”. Advance to the next slide by clicking your mouse or by pressing the “down arrow” key one time.
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 Link
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, XRays, 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
