Drill Why is a pendulum a good example of an energy conversion of PE to KE?
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(d) (F=force d=distance)
Engage What enables the match to burn?
Types of Energy KE PE
Forms of energy Mechanical Heat/Thermal Chemical Electrical Electromagnetic Nuclear
Mechanical Energy Energy of motion or position Sound Anything moving KE or PE Not 100% efficient much lost to heat
Heat/Thermal Energy The internal motion of an objects atoms and molecules. Measured by temperature. The faster particles move, the more energy they have. KE only
Chemical Energy Energy stored by chemical bonds in an object. When bonds are broken energy is released. When new bonds are formed energy is absorbed PE only
Electrical Energy Moving electrical charges. Electricity
Electromagnetic Energy Travel in waves. Light energy is a form. Magnetism is product. X-Rays Radio waves Gamma Waves
Nuclear Energy Energy stored in center(nucleus) of an atom Released in fission (breaking apart) Released In fusion (putting together) The sun is powered by this Most powerful PE only
